Checking the component, wiring and connector
Check camshaft reset valve connector for intermittent contact resistance, oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults and intermittent loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the signal cable between engine control module (ECM) #A13 and camshaft reset valve #5 for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check power supply cable #5 and camshaft reset valve #1 for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

Other information
- To connect the breakout box, see Connecting the breakout box, B5244T5, B5254T2 Connecting the Breakout Box.
- To access/replace the camshaft reset valve, see Variable valve timing solenoid, replacing Removal and Replacement.
- 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.
- For information about signals, see Signal specification Signal Specification, ECM.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
