OBD Diagnostic Codes

what car??

find your car on this site and i am sure you will find the code. http://www.troublecodes.net

It means you have an Evap purge control leak in the EVAP system.

Basically when you have gasoline in a car there are a lot of excess fumes, these fumes are routed through the EVAP system of the car, through a charcoal canister, and returned back to your gas tank as liquid fuel.

A leaking charcoal canister, Evap Purge solenoid, PCV lines or PCV elbows can cause this. Also a leaking gas cap can cause this.

I would recommend replacing the gas cap first. if that does not do it, check all the connections to the EVAP canister *located in the engine by the firewall*. If there are any leaks, change the elbows or lines.

IF the problem still exists you most likely need a new charcoal canister or Canister purge valve solenoid.

This is a Vehical Dependant Code. FOr many Diesels it means Glow PLug Sense fault.

On other cars it means other things.

Engine control system operating in failure mode

I had the same problem trying to locate the port for the OBD II on the Mitsubishi 2003 Galant.. It turns out that it is on the drivers side, under the dash where the steering wheel is located. I had to get on my back with a flashlight to get to it, but it is pretty easy to spot when you are down there.. Mine was White. I hope this helps you out..

you have to Call Honda and give them the Serial No. which is located on top of the device and they will give you the code.
