P0699

DTC P0699

Circuit Description
The engine control module (ECM) provides 5 volts reference voltage through the reference circuit 3 to the accelerator pedal position (APP) sensor 3. The ECM monitors the voltage on the 5 volts reference circuit 3. If the ECM detects the voltage is excessively high, this DTC will set.

Condition for Running the DTC
- The battery voltage is between 10-16 volts.
- The ignition switch is ON.

Condition for Setting the DTC
- The ECM detects that the 5 volts reference circuit 3 voltage is more than 5.5 volts.

Action Taken When the DTC Sets
- The ECM illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
- The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Failure Records.

Condition for Clearing the DTC
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- Clear the MIL and the DTC with a scan tool.

Diagnostic Aids
If an intermittent condition is suspected, the following may cause an intermittent:
- Misrouted harness.
- Rubbed through wire insulation.

Check for the following conditions:
- Damaged harness: Inspect the wiring harness for damage. If the harness appears to be OK, observe the "DTC P0699" display on the scan tool while moving connectors and wiring harness related to the sensor. A change in the display will indicate the location of the fault.
