CHECK HARNESS BETWEEN ECM AND ACCELERATOR PEDAL POSITION SENSOR CONNECTOR.

Measure the resistance of harness between the accelerator pedal position sensor connector and chassis ground.

Connector & terminal

(B315) No. 5 — Chassis ground:

(B315) No. 2 — Chassis ground:

QUESTION

Is the resistance less than 5 Ω?

Yes No

Repair the poor contact of the ECM connector.

Repair the harness and connector.

NOTE:

In this case, repair the following item:

Open circuit of harness between the ECM and accelerator pedal position sensor connector.

Open circuit of harness between ECM and engine ground
