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.

The Volvo Dealer quoted me $2250 to replace the clutch on my 2000 Volvo C70 (based on an hourly labor cost of $165 per hour!). Even after spending $160 to tow my car from the Volvo dealer to a location where YourMechanic could work on the car, I saved about $600! -The service was fast and professional. -The mechanic (Grzegorz) was friendly, knowledgeable, and even showed me the specific damaged parts that were replaced and explained the problem. - The mechanic (Grzegorz) worked part of the weekend so I could pick up my car on Sunday when it was more convenient. - I can't imagine why I would ever pay a massive premium at the Volvo dealer ever again - I've wasted so much money at that place over the 13 years I owned my car! - Initially I was a little cautious about using this service I found searching online, but I'm so glad that I took the chance and gave it a try. - I will definitely use yourmechanic.com again and have already recommended it to some of my colleagues at work.

Robert

Robert showed up for the 4 p.m. appointment today to look at my 2004 Volvo XC90. He was courteous, and tried his best to evaluate the problem. A foreign vehicle is very hard to disagnose, and I believe that after my experience with both Robert and another car mechanic at a different shop (who looked at the Volvo as well and did not charge us for diagnoses, since he could not figure out the problem) that it takes a Volvo specialist to evalute and to accurately diagnize the problem with this vehicle. Robert made a couple of guesses, however, he did not know exactly what the problem was. He told me that the car needed to be placed on a jack high in the air to completely diagnose the problem. He said I needed to take the car to a Kaufman tire to get a complete diagnoses while the car was on a jack high up in the air. He told me it would take 2 people to diagnose the problem. Robert tried his best, however your company did not have the resouses & equipment to accurately diagnose the problem (jack lift) according to Robert. Also Robert said it would take two people to diagnose the problem as well. I am going to take the Volvo to someone who works with Volvo's to accuratley diagnose the problem. I am confident that you will refund the $70 charge that you charged my credit card since Robert told me he was not able to accuretly diagnose the problem. Thank you. Rich Whitmer 404-379-1625
