How Much Does An Oxygen Sensor Replacement Cost?

How Much Does An Oxygen Sensor Replacement Cost?

On average, an oxygen sensor replacement costs about $340 for the US, oxygen sensor replacement costs can range from $277 to $402 according to, and other sources.

Cost Estimates for Oxygen Sensor Replacement

Labor price estimates range between $54 and $69, while parts prices range between $223 and $333. Estimates don’t include taxes and fees.

What is an Oxygen Sensor?

An oxygen sensor, commonly called an O2 sensor, is an instrument mounted in the vehicles exhaust system that continually oversees the oxygen content in the gases that leave the engine.

Before and after a catalytic converter are where the oxygen sensors are located. A vehicle can have up to 2 to 5 oxygen sensors, and occasionally, even more, depending on the vehicle.

How Does it Work?

The data from the oxygen sensor is used by the computer in the engine to assist in determining how much fuel is required so the engine will run as efficiently as possible. The sensor transmits this data by generating voltage once the sensor is heated. As the oxygen levels in the exhaust rise and fall the voltage will also rise and fall.

What are the Signs Related to a Faulty Oxygen Sensor?

A faulty oxygen sensor is one of the more typical causes for a check engine light to come on. Signs can include misfiring or hesitation from the engine, decreased fuel mileage, idling roughly or possibly stalling. A vehicle that fails an emissions test could be caused by a faulty oxygen sensor.

Is it Safe to Drive With a Problematic Oxygen Sensor?

A vehicle that has a faulty oxygen sensor may be driven safely until replacing the sensor. However, the vehicle won’t run as efficiently until the sensor is replaced.

Oxygen sensors will fail if they’re polluted with coolant, oil, silicone or other substances. When fluid pollution has caused an oxygen sensor to fail, the leak has to be fixed or the new sensor could also be damaged.

How Often are Oxygen Sensors Required to be Replaced?

On vehicles made since 1996, their oxygen sensors can go up to 100,000 miles or more prior to needing it to be replaced. That mileage will decrease on vehicles that are older.

Oxygen Sensor Vehicle Estimates

Chevrolet Silverado 1500 – $398-$424

Ford F-150 – $239-$286

Toyota Camry – $375-$591

Honda Accord – $191-$397

Honda Civic – $126-$366

Nissan Altima – $94-$285

Honda CRV – $301-$1113

Toyota Corolla – $266-$457

Chevrolet Sonic – $128-$138

Can I Replace the Oxygen Sensor Myself?

There is a pretty considerable disparity in cost between a professional mechanic replacing the vehicle’s Oxygen Sensor and replacing it yourself. If you feel you’re comfortable replacing it, you should try to replace the oxygen sensor yourself, because it’s a pretty simple job, it can save you 100’s of dollars.

How Can I Save Money on an Oxygen Sensor?

Don’t make the error of purchasing a replacement oxygen sensor from a mechanic or auto parts retailer. Find out the precise manufacturer part number for your vehicle, and then do a search online to find a much better price.

One other way to save money is not waiting for the sensor to fail. Check its function on regularly and have it replaced it if fuel efficiency decreases. This will reduce your overall average fuel costs each year. More vital, disregarding a faulty or failing oxygen sensor will ultimately cause the catalytic convertor to be damaged which is very costly to get replaced.

High catalytic converter prices are just the beginning though. Besides the repair itself, you have to take into consideration diagnostic costs and potential issues that arise because of the converter’s failure. For example, you might need to change one or more oxygen sensors, the muffler, or the exhaust at the same time. Before you start the repair, you’ll want a complete cost breakdown. To fix it could be worth more than the car itself.

How Much Does A Catalytic Converter Cost?

For cars made after 1981, the three-way catalytic converter is going to be a lot more expensive to replace than an older one. The costs for parts are going to be around $350-$1500, while parts and labor will be between $615-$2,200. Because the costs differ so much, you may want make sure you ask for a quote before you allow a professional mechanic to replace your catalytic converter.

The converter system is exposed to the elements, and may have studs that have become rusted, or bolts that hold it to the car’s engine. If the mechanic working on replacing your catalytic converter runs into any problems, they could take a while to work through them and finish the job.

How Is A Catalytic Converter Replaced?

A lot of catalytic converters are bolted in place in the exhaust system, although some are welded or clamped down. Whatever the case, the converter has to be loosened and then removed.

Several catalytic converters are built directly into the exhaust manifold, because they work more efficiently when they are hot. Not at any time touch a catalytic converter when the engine is running or any time shortly after it’s been shut off.

Signs Your Catalytic Converter Need Replacement

  • Your Check Engine light is illuminated.
  • Your vehicle refuses to turnover.

How Much Does A Mass Airflow Sensor Replacement Cost?

How Much Does A Mass Airflow Sensor Replacement Cost?

The average cost for a mass airflow sensor replacement is $328. Prices range from $269 to $387 for a mass airflow sensor replacement for the US in 2019 according to RepairPal.

What is a mass airflow sensor?

A mass airflow (MAF) sensor continually measures the volume of air going into an engine and sends that information to the vehicle’s computer.

How does the mass airflow sensor work?

The engine’s computer receives input from a lot of sensors and ensures they all agree with each other. An extremely important sensor that is used in reference to almost all engine operations is the mass airflow (MAF) sensor. The MAF sensor records how much air is entering the engine’s intake tube and reports the information it gathers to the computer. This allows the computer to calculate, or confirm, the amount of air entering the engine, amount of exhaust gas expected, how much fuel to send into the engine and a lot of other important factors. In addition, this sensor works closely with the manifold absolute pressure (MAP) sensor to allow significantly accurate response to ever changing conditions.

What are the symptoms associated with a bad mass airflow sensor?

If the MAF sensor sends an inaccurate signal, a couple of things happen. The engine’s computer will activate the check engine light, and the on-board diagnostic (OBD) trouble codes will reflect the airflow deviation noted by the MAF sensor. Depending on the reported volume of air, the engine may try to compensate for these conditions, making the engine burn excessive amounts of fuel and discharges black smoke from the exhaust. In this situation, the OBD trouble codes would also reference faults identified by the exhaust oxygen sensors. The engine can also have issues with idling roughly, not starting, hesitation, stalling, loss of power, misfires and fuel intake.

Can I drive with a mass airflow sensor problem?

When the MAF sensor fails driving can be hazardous. Because engine power will surge on and off, the vehicle may careen forward. Overall engine performance may start to be unpredictable and hard to control. It is preferable to tow the vehicle if any of the mentioned indicators are present. If the vehicle operates s, or near normally, driving the vehicle should not cause any issues.

How often do mass airflow sensors need to be replaced?

MAF sensors do tend to fail sometimes in a lot of vehicles. Failure rates are usually highest between 100,000 and 125,000 miles. The sensor can also get damaged during air filter changes, or anytime the engine intake gets serviced. Furthermore, a collision can cause a physical or electrical fault in the sensor.

How are mass airflow sensor problems diagnosed?

When the check engine light is on, and OBD trouble codes are referring to the MAF sensor, the servicing tech will begin by checking the vehicle for any signs of physical damage before starting to test. A scanner will be connected to the vehicle, and current conditions will be compared to the current readings from the vehicle’s different sensors. After these conditions are analyzed and compared, the tech relies on their training to understand which component needs to be tested. Once one or more components are showing evidence of possible failure, the servicing tech will begin testing with the most likely component, until the issue has been confirmed.

How is a mass airflow sensor replaced?

Replacing the MAF sensor is typically fast and easy. The sensor will usually be on or adjacent to the intake air tube, and the fastener can be a screw or a clip. After the sensor is replaced, the tech will examine sensor data, and confirm that the issue has been fixed.

OBD codes related to Mass Airflow Sensor Replacement

·         P0100: Mass or Volume Air Flow “A” Circuit

·         P0103: Mass or Volume Air Flow “A” Circuit High

·         P0104: Mass or Volume Air Flow “A” Circuit Intermittent

What to look for when dealing with mass airflow sensor issues

There is a genuine misconception that when an OBD trouble code is read, the component listed in the code should just be replaced. This isn’t always the case and can lead to costly and unnecessary repairs. The codes in fact refer to engine conditions being indicated by sensors. Most generic code readers are limited by their programming and are usually not advanced enough to test vehicle specific systems. A “MAF Sensor” title in a code doesn’t mean the sensor has failed, but rather gives the tech a code on where to begin their testing.

Can I replace the mass airflow sensor myself?

Just about anyone can replace a mass airflow sensor. They are usually removed with a clamp, or a screw, and have 1 electrical connector that sometimes can be a little tricky on some vehicles. Protecting the sensor while working is all there is to it, and some vehicles will reset associated codes when driving.

How To Pass Emissions An Test

To give your vehicle the best chance at passing the emissions test follow these tips.  By doing a little preparation you can save yourself the headache of getting your vehicle retested.  If you’ve got more serious problems with your vehicle you will likely need to have professional automotive repair to get your vehicle to pass emissions.

Change Engine Oil

Old dirty oil in your engine can release extra pollutants which can cause you to fail your emissions test.  It’s a good practice to have your oil changed before an emissions test.

Check Gas Cap Seal

One of the most common reasons people fail an emissions test is the gas cap.  Gas cap seals are exposed to heat, cold, rain, snow and the seals break down.  If air is passing by your gas cap it can cause your vehicle to throw a check engine light and fail your vehicle in an emissions test.

Have A Tune Up

Having your vehicle tuned up about 2 weeks before you need to get the test is a great precaution also.  Your vehicle benefits from regular maintenance and it will increase the chances of passing you emissions test.  Filters will be changed and your vehicle will be running at peak performance.

Check Tire Pressures

In some states your vehicle will be ran on rollers to test emissions as if  you were moving.  This is called a dynomometer.  If your tires have low pressure it could cause your motor to release higher levels of pollutants at speed.

Add A Fuel Additive

Fuel additives help clean carbons deposits out of your vehicle’s exhaust and intake system. If you’ve got extra carbon deposits around fuel injectors, cylinders, or in the exhaust it can cause your vehicle to fail an emissions test.

Use The Vehicle

If it is a vehicle you don’t normally drive, but want to get the registration done, you will need to make sure you drive it regularly for 2 weeks leading up to your testing.  This helps clear out the exhaust system and catalytic converter from carbon and other harmful pollutants.

Drive On Highway 20 Min Before Testing

On the day of testing you’ll need to drive the vehicle on the highway for about 20 min to warm up the motor.  This makes it so when you arrive at the emissions testing center you’ll be ready to pass with flying colors.

Reasons To Fail Emissions Test

There are 6 main reasons vehicles fail emissions testing.  A check engine light is a red flag that will cause you to fail along with bad O2sensors, too rich fuel to air mixture, bad EVAP systems, leaky, or incorrect fuel metering.

Check Engine Light

The check engine light in your vehicle comes on for numerous reasons.  If it is on you should stop by our shop and let us read the code to figure out what is happening with your vehicle.  Sometimes it can be as simple as needing a new gas cap to something more serious that if ignored can result in costly repairs.

Bad 02 Sensors

Vehicles today rely on O2 sensors to monitor exhaust fumes.  When they are not working properly the vehicle will likely have a rough idle or decrease in engine power.  You will also lose mountains of MPG efficiency if your O2sensors are not working properly.  If your vehicle is burning too much fuel it will not pass emissions testing as the toxicity of the exhaust will be too high.

Rich Fuel to Air Mixture

When gasoline is injected into your engine it is mixed with a proportion of air.  This is called the “air to fuel mixture”.  How much fuel is used to in each cycle of the pistons affects your fuel mileage, power, an carbon monoxide content in your exhaust.  If you are burning too much fuel you will not pass emissions tests.

Bad EVAP System

Your Evaporative Emissions Control System, or EVAP, stops gas fumes from being released into the atmosphere by your vehicle.  When vacuum hoses are cracked, loose, or broken it will cause the check engine light to come on.  Even a loose or broken gas cap will cause the EVAP system to throw a check engine light and prevent you from passing your emissions test.

Leaky Exhaust

Exhaust leaks will wreak havoc on a vehicle’s ability to pass an emissions test.  If your exhaust system is leaking it will make the O2 sensor read incorrectly.  If the exhaust from your engine isn’t being passed through the catalytic converter it is being released into the atmosphere in categorically illegal levels.  If your exhaust system is leaking, we can repair it so you will pass the emissions test in Arizona.

Incorrect Fuel Metering

How much fuel your vehicle uses is also part of emissions testing.  If your vehicle uses too much fuel compared to it’s make and model you will likely not pass your emissions test.  The right amount of fuel is sent to the engine to make it run smoothly.  If a fuel injector or engine control unit is malfunctioning it will use too much fuel and make it hard to pass an emissions test.

How Much Does Emissions Repair Cost?

The cost to repair your vehicle so it will past emissions testing will depend on what is preventing it from passing.  If it is simply a gas cap, it will cost around $30. In contrasts it costs about $200 dollars to fix an O2 sensor in most of today’s vehicles.  If the catalytic converter needs to be replaced it will cost over $1,000 dollars.  You will save money the sooner you bring your vehicle in when the check engine light turns on.  Small issues like O2 sensors can lead to the bigger more expensive problems such as replacing your catalytic converter.
