Diagnostic Trouble Code Description:
5 Volt Reference 1 Circuit
Possible Sensor Faults
ECM
Possible Related Diagnostic Trouble Codes
DTCP0641
Circuit / System Description
The engine control module (ECM) provides 5?volts to the following sensors:
The manifold absolute pressure (MAP) sensor
The engine oil pressure (EOP) sensor
The fuel tank pressure (FTP) sensor
The air conditioning (A/C) refrigerant pressure sensor
The accelerator pedal position (APP) sensor?2
The camshaft position (CMP) sensor (2006 Corvette and Cadillac CTSv 6.0 only)
These 5-volt reference circuits are independent of each other outside the ECM, but are bussed together inside the ECM. Therefore a circuit condition on one sensor 5-volt reference circuit may affect the other sensor 5-volt reference circuits. The ECM monitors the voltage on the 5-volt reference circuit. If the ECM detects that the voltage is out of tolerance, DTC?P0641 sets.
