I just changed my sister's 96 2dr accord ex timing belts. After driving for a couple of days she tells me her check engine light is on. I reset the ecu by the battery method and she drives it off again and 15 mins later the light comes back on. What do you guys think is the problem? Any help or suggestions is appreciated.

 

What code does it have stored?

 

I don't want to sound honda-illiterate or anything, but how do you know what codes pop up?

 

Try typing the trim (ie.. LX-i, EX) and check engine into the search engine. That's how I found out how/where to read my code.

 

try a tune up.

 

You need to pull the code and go from there. The CEL is coming on for a reason and the reason needs to be addressed.

 

Sometimes the engine light just comes on for no reason it happens to a lot of cars. But get it checked out at the garage to make sure.

The CEL doesn't come on for no reason. (unless the ECU is defective) It comes on because the ECU sees a problem.

 

Try checking the O2 sensors. That was happening to me I changed them and it went off

 

well a lot of cars i see has no problem with it and the lights still show and most of them are new cars too. how does that happen?

 

it may seem like there is nothing wrong but there is def something wrong. sometimes cars run rough because of the problem, sometimes cars run fine, but it still doesnt mean something isnt wrong. hell it could even mean that the gas cap isnt on tight enough! but in order to know whats wrong you have to pull the code. if you dont know how then go to autozone or somewhere and have them pull it for you. they will more than likely do it for you for free (thats what ive heard at least. good luck

The ECU sees a problem, turns on the CEL, and stores a code. If the CEL is on there is/was a problem. It does not come on for no reason. Check the stored code and diagnose accordingly.

 

ok i get it well i learned something new today
