    Po445 error code
    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.
