Cheers,

We'll get that posted in Techinfo, also. Thanks a bunch!

Are we able to access these codes through the DIC ?

No, I believe you have to connect a scan tool (via the OBD II connector) to access these DTC'*.

You need a code reader at least. a scanner will do even more and is worth the purchase but a code reader can be had for $40.

Now if you had the troubleshooting guide for them it be great.

Any idea how many pages that might take :?: Maybe I'll take requests....

Cheers,

Got some links maybe? I got a P440 "gascap" but thats not it and I need some really good info.

The actual code would be;

DTC P0440 Evaporative Emission (EVAP) System

I'll see if I can did out the diagnostic proceedure for you. I think people have dubbed it the 'gas cap' because they've got this code after not tightening the gas cap.

Cheers,

i got a DTC P1404 Exhaust Gas Recirculation (EGR) Closed Position Performance , i had replaced teh egr valve when i got a p0404 , figured it couldnt hurt, and now that i have now the p1404 pops up, can anyone help me
