STEPCHECKYESNO

1.CHECK HARNESS BETWEEN ECM AND ACCELERATOR PEDAL POSITION SENSOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

3) Disconnect the connector from the accelerator pedal position sensor.

4) Measure the resistance between ECM connector and chassis ground.

Connector & terminal

(B135) No. 22 — Chassis ground:

(B135) No. 31 — Chassis ground:

Is the resistance 1 M? or more?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2127 THROTTLE/PEDAL POSITION SENSOR/SWITCH "E" CIRCUIT LOW">Go to Step 2.

Repair the short circuit to ground in harness between ECM connector and accelerator pedal position sensor connector.

2.CHECK SHORT CIRCUIT INSIDE THE ECM.

1) Connect the connector to ECM.

2) Measure the resistance between accelerator pedal position sensor connector and chassis ground.

Connector & terminal

(B315) No. 3 — Chassis ground:

Is the resistance 1 M? or more?

Replace the accelerator pedal. Accelerator Pedal">

Repair the short circuit to ground in harness between ECM connector and accelerator pedal position sensor connector. Replace the ECM if defective. Engine Control Module (ECM)">
