Fuel Pump Control Module Internal Electronic Failure (P064A49)
MONITOR DESCRIPTION The fuel pump control ECU has a self-diagnosis function. If there is an internal malfunction, the fuel pump control ECU sends a malfunction signal to the ECM via the FPC drive circuit.
Based on the signal, the ECM judges that there is a malfunction in the fuel pump control ECU
Intermediate Shaft Speed Sensor "B" Circuit Short to Battery (P274512,P274514,P274531)
DESCRIPTION
The transmission revolution sensor (NC1) detects the intermediate shaft (C1 clutch)
speed and sends it to the TCM.
The TCM determines if gear mode should be entered by comparing the transmission
revolution sensor (NT) and (NC1) signals.
