I had my PCM fault code pulled today (CEL went on over the weekend) and got re-flashed. The code printed on my service report (P2402) isn't one I've seen on the forum or any of the TSB's... has anyone come across this one yet? I'm going to buy the workshop manual and wiring diagram soon- I don't suppose the fault codes are listed in there, are they?

hmm something i was working on and forgot about. sorry i'll work on a list soon. pm to me the code. btw i think i saw that code before in one of the post by rosenthal mazda. it might be the cat code for cat core temp being to hot.

P2402:EVAP system leak detection pump control circuit high.

Possible causes: EVAP system leak detection pump malfunction
: Connector or terminal malfunction
: Short to power supply in wiring harness
between EVAP system leak detection pump
terminal D and PCM terminal 4D
: PCM malfunction

hah i knew i had seen that one. its the one i had. they fixed mine with a flash that got rid of a software glitch. the glitch caused false failures under certain conditions. have never had it happen again.

Thanks much! Is this related to emissions under the hood, or something with the fuel system (loose gas cap, etc)?
