1) Turn the ignition switch to OFF.

2) Disconnect the connectors from ECM and oil flow control solenoid valve.

3) Measure the voltage between ECM and chassis ground.

Connector & terminal

(B137) No. 15 (+) — Chassis ground (−):

(B137) No. 14 (+) — Chassis ground (−):

QUESTION

Is the voltage less than 1 V?
