Answer 1

Everything about the IMRC is correct, there is only one difference, when it comes to this code , the PCM needs to be reprogrammed, this was a issue at one time when P2004 was occurring without any drivability, and according to the PID data the IMRC was not near any volts reading when closed, The solution was reprogram the PCM.
