My check engine light went on my 2000 Honda Accord 4 cyl EX ULEV. I then checked the Manual. It said to make sure the gas cap is tight and drive it for 3 trips. Which I did. Please note I flushed my transmission fluid and had my CPU replaced too b/c of a non starting car earlier this year. Autozone ran a check with their machine and the print out came out with one of these problems, please tell me what I should do:

Disconnect your battery for a few minutes, then reconnect it. Bet the light goes out.

 

Works for me everytime.

 

Resetting the computer is not going to solve the problem.

Normally, I would say to get the actual code, which would read something like P0171. In this case, however, it would not be very helpful since it's transmission-related. It sounds like your transmission is beginning to take a crap.

Have you noticed the car behaving differently while putting it into gear or during shifts?

It may be something as small as a sensor going bad, or it may be your transmission going south. Hard to say since we doing really know anything about your situation or how it drives...

 

How do I disconnect the battery safely without electrocuting myself or damaging the battery or car?

I had 2 error codes, I only copied down one, the guy at autozone made me write out the other causes and I forgot to write the code, b/c he said it was too many results to print: P0700 was the other code.

I don't notice any problems with the car. The light just happened to go on like a week ago when I was on the highway.

 

I pulled out FUSE 13 (Clock) on the passenger side fuses and put it back in. The check engine light went off, if it stays off I'll know it was built-in the computer to come on in a certain time if it doesn't I will have to go to a mechanic.

 

I'm not sure if the 2000 Accords "NEED" Honda tranny fluid or not, but, when you had the fluid flushed, was it replaced with Honda Tranny Fluid?? How many miles on the tranny when flushed? Was it ever flushed before?

The TCC code would have me worried if it was flushed and filled with a generic fluid. Pull the dipstick and have a look and smell of the fluid-report back.

If the other code is fuel related- get a new Geniune Honda gas cap and replace yours (it's under $10). That cleared up my fuel related code.

I've had the same code in my 96 for the three years I've owned the car. It sucks, because I don't think my torque converter is locking up, but the tranny shifts fine otherwise. It's just a pain to clear the code and get the car inspected within the drive time that the light stays off (usually about 80 miles).

 

The guy showed me the bottle and it was Genuine Honda fluid.
