P0699-ACCELERATOR PEDAL POSITION SENSOR (APPS) SUPPLY VOLTAGE TOO HIGH





For complete wiring diagrams refer to Diagrams/Electrical.


- When Monitored:

While engine is running.

- Set Condition:

High voltage detected at the APPS supply circuit.







Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.


1. (F855) 5-VOLT SUPPLY OPEN





Turn the ignition off.

Disconnect the APPS harness connector.


NOTE: Check connectors - Clean/repair as necessary.

Ignition on, engine not running.

Measure the voltage between the (F855) APPS #1 5-volt supply circuit at the sensor connector and battery negative.

Is the voltage between 4.5 and 5.5 volts?

Yes

- Replace the APPS.
- Perform POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

No

- Go To 2

2. (F855) 5-VOLT SUPPLY SHORT TO VOLTAGE





Turn the ignition off.

Disconnect the ECM harness connector(s).


NOTE: Check connectors - Clean/repair as necessary.

Ignition on, engine not running.

Measure the voltage between the (F855) APPS #1 5-volt supply circuit in the sensor harness connector and battery negative.

Is the voltage less than 1 volt?

Yes

- Go To 3

No

- Repair or replace the wiring harness.
- Perform POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

3. ECM





Turn the ignition off.

Reconnect the ECM harness connector(s).

Ignition on, engine not running.

Measure the voltage between the (F855) APPS #1 5-volt supply circuit at the sensor harness connector and battery negative.

Is the voltage greater than 6 volts?

Yes

- Replace and program the ECM.
- Perform POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

No

- Refer to the INTERMITTENT CONDITION Diagnostic Procedure. Intermittent Condition
