Checking The Wiring

Check the resistance of the camshaft reset valve between terminals #1 and #2.

The resistance must be approximately 3.7 Ω.

Check the signal cable between engine control module (ECM) terminal #A13 (#A13) and camshaft reset valve terminal #2. Check for a short-circuit to supply voltage.

Remedy as necessary.
