CHECK HARNESS BETWEEN ECM AND ACCELERATOR PEDAL POSITION SENSOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connectors from ECM.

3) Disconnect the connectors from accelerator pedal position sensor.

4) Measure the resistance between connector terminals of accelerator pedal position sensor.

Connector & terminal

(B315) No. 6 — (B315) No. 3:

QUESTION

Is the resistance more than 1 MΩ?

Yes No
