Checking The Component, Wiring And Connector

Check camshaft reset valve connector for intermittent contact resistance, oxidation according to Contact resistance and oxidation and intermittent loose connections according to Contact resistance and oxidation .

Check the signal cable between engine control module (ECM) #A13 and camshaft reset valve #5 for an intermittent open-circuit according to Open-circuit, intermittent faults .

Check power supply cable #5 and camshaft reset valve #1 for an intermittent open-circuit according to Open-circuit, intermittent faults .

Remedy as necessary.

Other information 

• To connect the breakout box, see Connecting the breakout box .
• To access and replace the camshaft reset valve, see Variable Valve Timing Solenoid, Replacing 
• With the ignition on and the camshaft reset valve connector disconnected the voltage at connector #1 should be approximately Ubatt and at connector #2 it should be a pulse modulated signal with a peak voltage of approximately Ubatt and with a frequency of approximately 250 Hz.
