Error Code P0017
Moderate Issue
DTC Code P0017 indicates a discrepancy between the Crankshaft Position and Exhaust Camshaft Position, suggesting a synchronization issue detected by the Engine Control Module (ECM) when comparing sensor signals.
What symptoms indicate Error Code P0017?
- Engine Light ON: The check engine light or service engine soon warning light illuminates, indicating a potential issue with the crankshaft and exhaust camshaft position correlation.
- Engine Hard to Start: Difficulty in starting the engine may occur due to improper timing between the crankshaft and exhaust camshaft, affecting engine performance.
- Engine Stall While Driving: The engine may stall unexpectedly while driving, which can be linked to the misalignment or incorrect timing between the crankshaft and exhaust camshaft.
What causes OBD code Error Code P0017?
- Low oil level can lead to insufficient lubrication, affecting the timing chain and camshaft operation.
- A mechanical timing fault, such as a stretched timing chain or damaged tensioner, can cause misalignment between the crankshaft and camshaft.
- Blocked oil passages can restrict oil flow, impacting the timing chain tension and camshaft positioning.
- A faulty Exhaust ('B') Camshaft Position (CMP) Sensor can provide incorrect data to the engine control module, leading to timing discrepancies.
- A faulty Crankshaft Position (CKP) Sensor can result in inaccurate crankshaft position readings, affecting engine timing.
How to fix OBD code Error Code P0017?
- Initial Inspection: Check for any additional DTCs related to camshaft or crankshaft position sensors. Inspect the wiring and connectors for damage or corrosion.
- Verify Engine Oil Level and Condition: Ensure the engine oil is at the correct level and in good condition, as low or dirty oil can affect camshaft timing.
- Camshaft Position Sensor Test: Test the camshaft position sensor for proper operation using a multimeter. Check for correct voltage and resistance values as per the manufacturer's specifications.
- Crankshaft Position Sensor Test: Test the crankshaft position sensor similarly to the camshaft sensor. Ensure it is functioning correctly and providing accurate readings.
- Timing Chain/Belt Inspection: Inspect the timing chain or belt for wear or misalignment. A stretched or misaligned timing chain/belt can cause timing discrepancies.
- Camshaft Actuator Inspection: Check the camshaft actuator for proper operation. Ensure it is not stuck or malfunctioning, which could affect camshaft timing.
- ECM/PCM Software Update: Check for any available software updates for the ECM/PCM that may address known issues with camshaft/crankshaft correlation.
