So recently I've had the Check Engine Light come on while driving, when I turn the car off and turn it back on the CEL goes away. Now when I short the connector and check to see what code it is I have a # 40 come up...but what in the hell is CEL # 40?

Even if I reset the ECU, the code comes back within a day. I've noticed that this code only comes on when I drive the car after it's been sitting for a while. If I drive the car for a while, then turn it off, then start it again and drive the car the CEL doens't come back on. I have a '01 Type-R running an S200 with a Hondata modified P06(P28) ecu.

Anyone have a clue to this?

do you have laptop hooked up to pull the code? i thought thats the only way to pull the code on our cars.

 

Maybe check the sequence of lights again.

And use this for reference:

You are wrong.

 

explain please.. i'd liek to know how to retrieve cel codes with hondata without laptop..

 

Short the connector and see how many times the CEL blinks.

 

maybe i have this mixed up.. i thought you can't pull the codes with hondata with connector alone..

 

you can pull codes with the hondata. i have done it many times. but a code 40, never heard of it.

Thanks BPR...I've pulled this same code 5 different times, I even went back to check the code when I found that #40 didn't exist.

Austin, are you sure your reading the blinks right? How many blinks total?

You sure it's not code #4? If you are really pulling a code #40 (4 long blinks), there is a problem within the ECU or the Hondata. If you have datalogging, you could run with the datalogging going, and then replay the event when the code trips. Just examine all of the sensors, and look for anything unusual.

Yep...quite sure that it was a #40, pulled it 8+ times. After speaking with Hondata they think that right after start something is going on with the short/long term fuel trim. If I start the car, run it for a minute, turn it off then drive away the CEL doesn't come on.

also pulling a code 40 on my fresh s300 ecu is a p05 converted to p28. any thoughts?
