Does anyone know how to trouble shoot this code? Just had the PCM replaced and then got this error.

Thanks

Looks like it could be a gas cap leak or a leak associated with the evap. System cannisters/hoses.

You're lucky I took the time to fill out the registration, I just got this code today, don't feel like fixing it yet but I figure I'd help you out.

Error code P0445
"The PCM has determined that a short circuit condition exists in the electrical circuit for the purge control valve in the evaporative emmission control system"

So it's a evap/emissions code saying you have a short that is going to your ecu/pcm or your sensor is shorting out.
