Model Years Affected: 1990, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2007, 2008, 2009

Average Mileage: 122,298 mi (21,000 mi - 255,000 mi)

Verified

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.

    I have had error code 420 for several years I have change the oxigen sencor in front and behind the Catalic converter and I still have the code 420. the exhaust system looks ok there are no leaks and no loud exhaust sound. I can get rid of the code. What should I try next?

    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?

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

  • 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.

    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

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

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

    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!
