(The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
| - Accelerator pedal position sensor
- Open or short in accelerator pedal position sensor circuit
- ECM
|
P0653
| Power voltage (5 V as standard) supplied from ECM to accelerator pedal position sensor is higher than threshold
(The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
|
- УКАЗАНИЕ:
- These DTCs are set when the ignition switch is in the ON position.

INSPECTION PROCEDURE
| 1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0652 AND/OR P0653) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position.
Turn the tester on.
Enter the following menu items: Powertrain / Engine and ECT / DTC.
Read the DTCs.
- Result:

| Proceed to
|
DTC P0652 and/or P0653 are output
| A
|
DTC P0652 and/or P0653 and other DTCs are output
| B
|
- УКАЗАНИЕ:
- If any DTCs other than P0652 and/or P0653 are output, troubleshoot those DTCs first.
| 2.CHECK HARNESS AND CONNECTOR (ACCELERATOR PEDAL POSITION SENSOR - ECM) |
Disconnect the accelerator pedal position sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
