CHECK HARNESS BETWEEN TUMBLE GENERATOR VALVE POSITION SENSOR CONNECTOR AND ECM CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from tumble generator valve position sensor.

3) Measure the resistance of harness between tumble generator valve position sensor connector and engine ground.

Connector & terminal

(E54) No. 2 — Engine ground:

QUESTION

Yes No

Repair the harness and connector.

NOTE:

In this case, repair the following item:

Open circuit of harness between tumble generator valve position sensor and ECM connector

Poor contact of coupling connector
