#1668 of 1688 got a code reader?
by steve_ HOST

A reporter is looking to hear from consumers who own a "code reader" - either an app or an appliance that allows the user to tap into his/her car's diagnostic system to understand why the Check Engine light etc is on, and perhaps shut it off. If you have used one of these apps or systems and are willing to share your story with a reporter, please email PRedmunds.com no later than Monday, March 5, 2012 with your daytime contact information.

Check engine light and gas cap. I have repeatedly had the problem. After an expensive diagnostic test I bought the recommended new gas cap. The problem continued! My discovery is that the filler spout to the gas tank is out of round and will not seal properly. To determine if yours is not round it should be checked with a dial indicator as it is not detectable by the naked eye. I have contacted American Honda and have a case #, but they need more evidence to determine if this should constitute a recall item.

#1673 of 1688 check engine light blinking - 96 GrandAm
Oct 02, 2012 (4:20 am)
Car drove well this morning until I had to stop for a light. The check engine light comes on once in a while - after gas fillup, but this morning it started to blink and the car started to shake when I applied the brakes - like it wanted to stall. Once I started driving again, the light stopped blinking, but stayed on.
Any ideas? Got me to work, but it's a 20 mile drive back home.

A loose or leaking gas cap would cause the CEL to come on, and that would fit with the fact it comes on sometimes after filling up. But, I don't think that would cause a driveability problem.

A blinking light is more serious than a steady one. Sounds like some kind of misfire is overheating the catalytic converter. Just keep an eye on that light and you should be okay for 20 miles. Keep your speed down and if there's a way home without hills, do that.

Check engine light came on 42k miles, code was bank one sensor 1 heater circuit. Replaced o2 sensor, same code. replaced o2 sensor again same code. mechanic said bad wire was the culprit and replaced a wire and fuse box. same light and same code remained. Took to dealer and they said I needed a new engine wiring harness and the cost was $1050.00 They reset the computer but the same code remains. I am not sure what to do next.

Well the first thing would be to get to a good mechanic. Obviously these guys don't know what they're doing.
Are you by any chance in the San Francisco area? I could send you somewhere.
Do you remember the number of the code you read? Just because the code refers to the 02 sensor that doesn't mean the 02 sensor is bad--it only means the 02 sensor is reacting to some irregularity--you could for instance have a catalytic converter problem or a wiring problem.
