Last year, my check engine light came on during a raining day and the car starting shifting higher than usual. After taking to a mechanic to read the code, I was given the code and told it was an error with the TPS sensor. When they put a multimeter up to it, they found the voltage on the potentiometer was all over the place. I got two estimates for $420 and $500 to fix the problem. The problem was intermittent and could be corrected by shutting off and restarting the car. Before I had a chance to take it in, it stopped happening after 2 days. It's my belief the TPS sensor got really wet and eventually dried off. The problem hasn't come back in over 6 months and the car drives perfectly fine.

The two shops I got quotes from, are shops that I normally go to. As much as I do like these shops, I get the feeling that if that code is still stored in memory they're gonna try and get me for that ****... and my inspection is up next month. Can I clear this code or do I need a specific device to do it? The car in question is an '04 Honda Civic. I do not want to get screwed by either shop, and be forced to replace something that is obviously functioning perfectly fine now. I know a Check Engine Light is an automatic "Fail" in PA but I don't know if old error codes stored in memory would "Fail" it too.

Really need some advice on this. Thanks guys!

Pull fuse #6 (15 amp) out of the fuse box under the hood. Wait 30 seconds before reinstalling it. That will reset the ECU.


It is recommended that you do the Idle Relearn after resetting the ECU.

- Turn all electrical items OFF. (radio, wipers, heater, defogger, etc etc)

- Start the car and hold it at 3,000 RPM until the radiator fan comes on, or until the coolant reaches the operating temperature of 194 °F

- Take your foot off of the accelerator and let the car idle for at least five minutes.

- Done.
