Signal Too Low - Intermittent Fault

Signal too low. Intermittent fault

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 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 short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

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 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.
- 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).
