What does P0018 mean?
What does P0018 mean?
Crankshaft Position – Camshaft Position Correlation
OBD-II Code P0018 is defined as a Crankshaft Position – Camshaft Position Correlation. The engine control module (PCM) uses a signal from the camshaft position sensor to determine the the proper time to fire the fuel injectors and ignite the spark plugs.
How do I fix error code P0018?
What repairs can fix the P0018 code?
- Repair or replace the wiring to the camshaft sensor on bank 2.
- Repair the wiring or connection to the camshaft OCV.
- Replace the camshaft OCV or the camshaft sensor for bank 2 camshaft.
What can cause a P0018 code?
What are the Possible Causes of the P0018 Code?
- Camshaft variable timing solenoid failure.
- Low engine oil level.
- Incorrect engine timing.
- Engine oil doesn’t meet the manufacturer’s requirements.
- Variable valve timing actuator failure.
- Worn timing chain.
- Failed timing chain tensioner or guides.
Do you have to disconnect battery to change camshaft position sensor?
Disconnect your negative battery cable. This should be done any time you work with sensors or electrical components. It may be easiest to remove and replace the camshaft sensor from under your vehicle, but it can also be done from the top by removing the air filter housing.
Will a car run with a bad camshaft position sensor?
If you ignore the symptoms listed here and your camshaft position sensor fails, your vehicle will not start. As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
What is the camshaft position sensor bank 2?
The CMP sensor measures the exact rotational position and speed and position of the camshaft. The data that the CMP gathers is important because it’s used by the ECM to control the ignition spark and the fuel injector timing.
