P0017 - Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor B)
The ECM monitors both Crankshaft and Camshaft speed and position using sensors, this information is then used to calculate Fuel Injection, Ignition and Variable Valve Timing Control.
Fault Code Explained
This fault codes indicates that the ECM is receiving conflicting engine position information from the Camshaft Position Sensor and Crankshaft Position Sensor. This fault code can be due to one of the sensors or the sensor wiring being faulty, it can also be due to the valve timing being incorrect.
It is recommended to check the following systems and components.
- Crankshaft Position Sensor Circuit
- Camshaft Position Sensor Circuit
- Timing belt / Chain
Checks should include sensor outputs, wiring, physical checks of Valve Timing and teeth / rotors on Camshaft and Crankshaft pulleys.
