Checking wiring and connectors
Check signal cable between engine control module (ECM) #A13 and camshaft reset #2 for an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults .
Check power supply cable #5 and camshaft reset valve #1 for an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults .
Other information
- To connect the breakout box, see Connecting the breakout box .
- To access/replace the camshaft reset valve, see CAMSHAFT SEAL/VARIABLE VALVE TIMING (VVT) UNIT, REPLACING .
- With the ignition on and the camshaft reset valve connector disconnected the voltage on 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.
