2011 Chevrolet Traverse P0014 Code: Diagnosis and Fix After Engine Overhaul

Model: 2011 Chevy Traverse Fault Code: P0014 Posted: 2017-01-04 16:13

I own a 2011 Chevrolet Traverse. The engine was recently removed due to a failing bearing and underwent a full overhaul, including new bearings, piston rings, and a timing chain replacement. After reinstallation, the vehicle will crank but won't start — it only starts the first time when the positive battery cable is disconnected and then reconnected. Once started, it dies immediately. The engine is now throwing diagnostic code P0014. I'm seeking advice on how to resolve this issue. Any insights would be greatly appreciated.

Only seeing P0014? Security light not illuminated? Start with fundamentals: fuel pressure, injector pulse, and spark at the plugs. For P0014, first verify that there's a 12V signal on the pink/black wire to the VCT solenoid — this is critical. The control circuit must be grounded properly. If no voltage or grounding is present, use an OBD2 scanner to check the exhaust bank 1 camshaft offset; likely issue: mistimed cam position.

Thanks for the response — security light is not on. However, the vehicle also shows a mass airflow (MAF) sensor fault and issues with both camshaft sensors A and B. Both were replaced on the radiator side (bank 1), but the problem persists, especially related to exhaust system diagnostics.

You mentioned MAF and camshaft sensor faults — could you please post all diagnostic trouble codes (DTCs) being triggered? This helps identify root causes more accurately.

The vehicle currently shows only P0014 and a MAF-related code. My mechanic has already replaced both camshaft sensors.

Is there a MAF fault code? P0014 — The ECM detects that the actual camshaft position angle differs from the desired angle by more than 7–8 degrees, or shows a slow response with deviation over 1.5 degrees lasting longer than 2 seconds during testing. Use an OBD2 scanner to command the cam actuator and monitor 'Camshaft Position Variance' — it should be under 2 degrees. A possible root cause: faulty cam position solenoid.

Yes, there is a MAF code. My mechanic has already replaced the camshaft position actuator solenoid.

I apologize — I mistakenly wrote 'MAFIA' earlier. The correct code is MAF (Mass Airflow), and only MAF and ECM codes are showing.

Do you have a MAF code? Do you have an ECM-related code? Has the mechanic replaced sensors or solenoids? If solenoids were replaced, check camshaft position using a scanner. The ECM should detect no deviation greater than 7–8 degrees or slow response over 2 seconds during testing.

We have replaced both the camshaft position sensors and the camshaft position actuator solenoid. We also replaced the manifold. The vehicle still shows MAF and ECM codes.

What are the exact codes? An ECM code is concerning — it may indicate a deeper issue. What does your scanner show for camshaft position? Is it within acceptable range (±2 degrees)?

The scanner shows P1014: Exhaust Camshaft B timing — over-advanced on Bank 1.

Two posts above you said 'we get MAF & ECM codes' — what are the full list of all DTCs? What does the scanner show for camshaft position (positive or negative degrees)?

DTCs: P0014 (Exhaust Bank 1 Camshaft Position Timing — Over-Advanced), P0102 (Mass or Volume Air Flow Sensor A Circuit — Low Input)
