P0697-SENSOR SUPPLY 3 VOLTAGE TOO LOW





For a complete wiring diagram Refer to Section 8W


  • When Monitored:

    With the ignition on.

  • Set Condition:

    The ECM detects low voltage for 0.1 second on the Sensor Supply #3 circuit which supplies 5-volts to the Inlet Pressure Sensor and the APP Sensor #2.


Possible Causes
 
WIRING INSPECTION
 
INTERMITTENT CONDITION
 
5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
 
ACCELERATOR PEDAL POSITION SENSOR
 
INLET PRESSURE SENSOR
 
ENGINE CONTROL MODULE
 




Diagnostic Test

1.CHECK FOR ACTIVE DTC

NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.


NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.
