Common Symptoms
- Engine no-start condition
- No camshaft position signal to other modules
- Check engine light on
- Fuel injection timing lost
Probable Causes (Ranked by Likelihood)
- ECM camshaft signal output driver failure Very High
- Open wiring in cam signal output circuit High
- Failed camshaft position sensor Moderate
- Damaged connector in signal distribution circuit Low
Step-by-Step Diagnostic Procedure
-
Verify camshaft position sensor signal at ECM
-
Check output circuit wiring for continuity
-
Test ECM cam signal output to other modules
-
Inspect all connectors in cam signal circuit
Frequently Asked Questions
What is the cam signal output circuit?
The ECM receives the cam position signal and redistributes it to other modules that need it for timing calculations, fuel injection, and ignition.
Can a bad cam sensor cause P2614?
It can contribute, but P2614 specifically refers to the output circuit from the ECM, not the input from the sensor. Check the sensor separately.
Why won't my engine start with P2614?
Without a camshaft position reference, the ECM cannot determine which cylinders need fuel and spark, preventing sequential fuel injection.
