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

* B150 fuel tank pressure (FTP) sensor

* B17 barometric pressure (BARO) sensor

* B37 engine oil pressure (EOP) sensor

* B47B fuel rail pressure (FRP) sensor

* B1 A/C refrigerant pressure sensor

* All four B23 camshaft position (CMP) sensors

DTC P0651

The 5 V reference 2 circuit provides 5 V to the following sensors:

* B25B clutch pedal position (CPP) sensor, if equipped

* B26 crankshaft position (CKP) sensor

DTC 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

DTC 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.

Circuit/System Verification

1. Ignition ON, observe the DTC information with a scan tool. DTC P0641, P0651, P0697, or P06A3 should not set.

2. Observe the appropriate scan tool 5 V Reference Circuit Test Status parameter. The parameter should display OK or Not Run.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Note: Additional DTCs will set when disconnecting the components.
