P0016: Crankshaft Position A – Camshaft Position Correlation (Bank 1)

Last Updated on May 30, 2020 by themechanic

Every vehicle has a crankshaft position sensor which monitors the crankshaft’s position and sends information about the position to the engine control module. As part of the ignition system, the crankshaft and the engine control unit work together to manage the spark timing.

The crankshaft position also works in harmony with the camshaft position sensor to manage both spark timing and fuel delivery to the engine. The camshaft position sensor lets the engine control unit know when fuel should be injected into the cylinders. It does this by monitoring the position of the camshaft. Both sensors must be functional for the engine to generate power properly.

If the engine control unit ever receives inadequate information from either the crankshaft position sensor or the camshaft position sensor, then it will trigger trouble code P0016. All you need to do is run a diagnostic scan and see if trouble code P0016 comes up. If it does, then your camshaft position sensor or crankshaft position sensor may be in trouble in Bank 1.

The most common symptoms of trouble code P0016 include a Check Engine warning light, rough running engine, weak acceleration, poor fuel economy, and/or an engine that does not start at all. Your first instinct will be to assume that you have a bad camshaft sensor or crankshaft sensor. However, don’t automatically assume this is the cause of the problem. Other possible causes include a bad engine control module, bad timing belt, and bad crank sensor wiring.

If you don’t get this problem addressed soon, then you’ll experience trouble starting your engine and/or engine hesitation. The longer you wait to resolve the issue, the more likely that the internal components of your engine will suffer damage. In the meantime, you’ll experience driving issues on the road which could put lives at risk. The drivability issue is not an immediate problem, but it will eventually happen the longer you continue to do nothing.
