P0017 is a generic powertrain code that stands for “Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor B).”
This code indicates that the crankshaft and camshaft position sensor for the Bank 1 exhaust camshaft don’t correlate signals with each other.
The camshaft opens and closes valves, letting an air-fuel mixture into the cylinders. This is followed by a spark causing this mixture to combust — which drives the cylinders. The crankshaft translates the cylinders’ force into a circular motion, used to rotate the wheels.
The crankshaft position sensor (CKP sensor) and the cam position sensor (CMP sensor) must work harmoniously to control the spark, fuel delivery, and timing. When they don’t, the engine doesn’t function properly, triggering the P0017 error code.
Some car manufacturers, such as GM or Chevrolet, have their own definition of P0017. P0017 on Chevy cars, for example, translates to “Crankshaft Position – Exhaust Camshaft Position Not Plausible.”
Irrespective of the different names coined by manufacturers, the P0017 code simply means that the PCM thinks the difference between the crankshaft position and the camshaft position surpasses specification.
P0017 is a common problem among the following makes: Chevrolet (especially a Chevy Colorado), GMC, Cadillac, Buick, and Mercedes Benz.
Here are some of the most common telltale signs of the code P0017:
It’s possible to continue driving your car with a fault code P0017. However, it’s best not to do so because it can cause drivability issues like stalling, poor acceleration, low engine power, and no starts.
Since this code can occur due to several issues, including a mistimed engine, it can cause destructive engine damage and leave you with expensive repairs.
Moreover, if you don’t fix the DTC P0017 on time, it can cause carbon deposits to form on the valves and pistons, damaging your car’s spark plugs. It can also lead to engine misfiring.
Here are some of the many problems that may trigger a code P0017:
Timing chain or timing belt issues:
Sensor and actuator issues:
Engine oil issues:
Other issues:
