      O2 sensor for 2000 Camry

      I have a 2000 Camry. I had this sensor replaced once by the Dealer at about 40,000 miles. I am replacing it again at 64,000 miles. OBD Codes P1150 and P1155 were the reason for the change. After pulling it out I noticed it was carbon-ed up a bit. This is supposed to be the OEM part for the Camry.
      Check engine light is now out after the replacement.
      Hopefully it will last longer this time.

      Comments about Denso Air Fuel Sensor - Direct Fit:

      Check Engine light was on and I needed to pass Emissions inspection in State of MD. The code for this O2 sensor registered on computer so we replaced and passed inspection. The Check Engine Light was back on after 2 weeks with the same code.
