DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.

Conditions for Clearing the DTC

DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.

Diagnostic Aids

P0641

The 5 V reference 1 circuit provides 5 V to the following sensors:

* B150 fuel tank pressure (FTP) sensor

* B17 barometric pressure (BARO) sensor, throttle inlet absolute pressure sensor

* B47B fuel rail pressure (FRP) sensor

* B1 A/C refrigerant pressure sensor

* All four B23 camshaft position sensors

P0651

The 5 V reference 2 circuit provides 5 V to the B26 crankshaft position sensor.

P0697

The 5 V reference 3 circuit provides 5 V to the following sensors:

* B74 manifold absolute pressure (MAP) sensor

* B107 accelerator pedal position sensor 2

P06A3

The 5 V reference 4 circuit provides 5 V to the following sensors:

* B106 throttle position sensor

* B107 accelerator pedal position sensor 1

瀚慖f the condition is intermittent, move the related harnesses and connectors with the engine operating. Monitor the scan tool 5 V Reference

Circuit Test Status parameters for the affected components. The Circuit Test Status parameter will change from OK or Not Run to Fault if

there is a condition with the circuit or a connection.
