P0018 P0018 OBD-II: Crankshaft and Camshaft Position Correlation Error
What P0018 means for you
This code indicates a timing issue between the camshaft and crankshaft, which can affect engine performance.
Symptoms
- Reduced engine efficiency
- Higher fuel consumption
Common causes
- The engine control module (PCM) relies on data from the camshaft position sensor to accurately time the firing of fuel injectors and spark plugs. It compares this data with the crankshaft position signal to ensure proper engine timing. In modern vehicles, a variable timing system is employed to optimize the camshaft timing in relation to the crankshaft, enhancing fuel efficiency and overall performance. If the camshaft is misaligned with the crankshaft, the PCM triggers code P0018.
