Signal too high. Permanent fault

Checking the wiring




- Ignition off
- Check the resistance of the camshaft reset valve between terminals #1 and #2. The resistance must be approximately 7 ohms at 25°C
- Check the signal cable between engine control module (ECM) terminal #62 and camshaft reset valve terminal #2. Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Remedy as necessary.
