P0697-SENSOR SUPPLY 3 VOLTAGE TOO HIGH

For a complete wiring diagram Refer to Section 8W

• When Monitored:

  With the ignition on.

• Set Condition:

  The ECM detects a short to 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.

Diagnostic Test

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.
