Oxygen Sensor Replacement Service & Cost

What is the Oxygen Sensor all about?

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor.

Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor.

If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.

Oxygen Sensor-MATROX-1

Keep in mind:

  • Many oxygen sensors are damaged by leaking oil or coolant. If that is the case, the cause of that leak needs to be identified and repaired, or else the replacement oxygen sensor will be damaged as well.
  • New vehicles require specific oxygen sensors, and not the universal sensors that were common prior to 1996.

How it's done:

  • Scan the computer in the car for codes.
  • Inspect for vacuum leaks and holes in the exhaust system.
  • Remove and replace the oxygen sensor if it is bad.
  • Check electrical connections.
  • Check for proper operation of oxygen sensors.
  • Clear diagnostic codes.
  • Test drive car.

Our recommendation:

Keep up with the tune-ups. If check engine light is on, don't drive the car too long without getting it inspected. If check engine light is flashing, pull over and get the car towed to avoid costly repairs. Ask the mechanic to inspect the vacuum hoses and leaks in the exhaust system. If the vacuum hose or exhaust system is leaking, it will display an oxygen sensor fault code. Replacing an oxygen sensor may not fix the problem.

What common symptoms indicate you may need to replace the Oxygen Sensor?

  • Check Engine light is on.
  • Car is getting poor gas mileage.
  • Emission test fails.

How important is this service?

Your vehicle has multiple oxygen sensors, and they all help the car run optimally. The front sensors measure how much oxygen is in the exhaust stream to measure how rich or lean the gases leaving the gas chamber are. The rear sensors measure the oxygen content of the gases as they leave the catalytic converter. The oxygen sensors then relay this information to your vehicle’s electronic control unit, so that it can adjust as necessary. Because cars depend on an ideal fuel-to-air ratio to function optimally, the oxygen sensors are leaned on for engine performance. When your oxygen sensors fail your car will run less smoothly, get worse mileage, and have worse emissions.

15 June 2015 Review: YourMechanic.com Recently, I had the opportunity to check out a service that I had, for quite awhile, wondered about and would it fit with the ever-changing consumer worldview. Okay, at least, here in the United States. YourMechanic.com offers to come to you and service your vehicle's needs. While you continue your work day; they continue theirs. When all is done, that's exactly that. They're done with their day, you're done with your day and the day-off your car unexpectedly took is also done. Now, you're back on the road or at least able to head out if there's someplace you have to be. Although this may not be a new service; it is for me. I'm glad I found it, used it and now I can recommend it. The mechanic I met, Peter, came with 35 years of experience, licensed, prepared and engaged. I haven't found that at decades old, established companies anywhere, ever. Perhaps, that old model, along with its particular brand of hassles and drawbacks is becoming obsolete. One thing for sure, it won't be missed by me. In as much as the auto/mechanic industry is not my primary area of expertise, allow the following illustration which draws on my personal background to drive home the point: If YourMechanic.com were to announce an Initial Public Offering (IPO) tomorrow, you bet you'd find me among those first in line positioned to grab up as many shares as possible for a long term "hold." Regards, David Duke, Phoenix, Arizona *Note: Please strike this note from the official review as it is intended for inter-office use only. Please feel free to correct any glaring typos I may have overlooked. I am submitting this with a deadline in mind.

Jeffrey worked on my neice's car twice and she was so pleased with the service and tech that there's no way I wanted to call anyone else! Right on time, got right to business, and clearly knew what he was doing! Would highly recommend Jeffrey to friends and family, and he will be the first person I call the next time I need a mechanic! Thank you very much!

Had a coolant leak. Needed an engine gasket and thermostat replaced. Also needed a flush of the coolant system and oil change. It was a very long job and Danny was dedicated to getting it done. He also gave me other automotive advice and answered all of my questions thoroughly. The car is no longer overheating or leaking. He did a great job. I would definitely use this service again.
