Review Of 2003 Camry Check Engine Light Code Ideas. Unsure why it failed just had some transmission & engine work done at the dealership a couple of weeks ago unsure why it wasn't detected at that time when my vehicle was covered by the extended warranty coverage. I went to autozone to find out what the check enginge light was for and was given p0031.
Web i have a 2002 camry v6 with 149,000 miles. Is it ok to drive with a check engine light on? Typically the p0420 code triggers the check engine light if the readings of the two sensors are similar.
