Model Years Affected: 1995, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2007, 2008

Average Mileage: 120,416 mi (105 mi - 255,000 mi)

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

Check engine light came on. Temporarily disconnected battery to clear the error and turn off the light. Light came back on quickly and motor wasn't running right. Repair shop replaced the oxygen (O2) sensor and it fixed the problem. Cost about $300 for parts and labor. Seemed too expensive to me. When the top O2 sensor takes about 3 min to replace.

A couple of days after I bought the car the engine light came on. Auto Zone checked it and it is the oxygen sensor. Can't afford to get it fixed. The dealer refused to give me a history of the car. Sunday the car stalled on me. Temps at 0 here in Michigan but it started ok, I warmed it up and drove about 3 miles and all of a sudden the brakes didn't work and the engine stalled. Wouldn't start again immediately. I parked for a few minutes to get help. When we got back it started fine and I got home. Did the same thing again Monday. Could the oxygen sensor cause this?

Replaced O2 something. Had to pull fuel tank to get to it. Took care of problem and gas mileage resumed normal.

Check engine light stays on. Keep resetting it but it comes back within 20 miles.

I had codes P0125 &P1155 that required replacing both the front&rear air fuel ratio sensors to correct the check engine light problem.

Check engine light is ALWAYS on! I can't pass a 10.00 emissions test due to this stupid light. Replaced EGR valve (thanks for nothing AUTOZONE!) Have tried "guaranteed to pass" additives, still no luck. Tags have been expired now for 7 months! Ready to bribe the tech at emissions testing! arghhhhhhhhh

total of 4 sensors replaced by Toyota at a cost of approx. $3000. I am disgusted. This is my 4th Toyota, but now my LAST.

Engine light repeatedly comes on due to the same Emissions code and the warranty for federal emissions codes expires at 8 years or 80000 miles, which ever comes first....I am obviously just past the requirements with 90000 miles and 9 years. But, it is deeply disturbing that they obviously know this is a problem and even have a "deadline." You see, they added this extended warranty because of the same issue that they had with previous Camry's (I think '96-'98) had caused quite an uproar & ended in a class action lawsuit. I wish they would have another class action suit OR make the part(s) more durable OR my favorite solution, FIX IT NO MATTER WHEN IT HAPPENS!

I have a 1997 Toyota Camry V6. I got the Engine Check Light with a code of P0420. I replaced both forward sensors (see video at http://youtu.be/1zAFcw_YtTs) and the ECL did not come back on. I thought it was interesting that the light went away immediately and I didn't have to have it reset.

O2 sensor failed and because I had a picture of my wife on the dash never saw the engine light was lit. Saw it was on when I let my grand daughter use the car and was standing out side and saw the glow of the light. dont know how long the sensor was bad, but the car ran ok. Took it to a shop and paid what I think is alot for a small item.

I recently bought this car, and the owner replaced two of the three oxygen sensors, but not at the same time and not with the same brand. I get the check engine light that tells me that the oxygen sensors AND catalytic converter are bad. I've had two mechanics look at my car--both said the oxygen sensors are fine, one said the cat was fine, and the other said the cat was in ok shape but not great. I don't have any symptoms of a bad cat (rotten egg smell, hot floors, glowing cat) or any other problems, so I haven't done anything about it. My best guess, as a novice, is that the two oxygen sensors don't agree (which causes the computer to blame the misread on the cat) because they're different brands/qualities. Just hope I can figure out a solution before my emissions test in August (which it passed with flying colors last August just days after the oxygen sensors were replaced).

Check engine light came up. On taking to local dealership, the O2 sensor needs replacement. The initial estimate is $ 667/-. I decided to hold off and investigate where else can I get this replaced.

Engine light illuminated due to oxygen sensor needing replacement. Once it was replaced, the engine light was no longer lit.
