DTC P0365: Camshaft Position Sensor "B" Circuit (Bank 1); DTC P0367: Camshaft Position Sensor "B" Circuit Low Input (Bank 1); DTC P0368: Camshaft Position Sensor "B" Circuit High Input (Bank 1) [10/2017 - 12/2021]: Description
The camshaft position sensor for the exhaust camshaft (EV1 signal) consists of a magnet and MRE (Magneto-Resistive Element).
The exhaust camshaft has a timing rotor for the camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, which affects the magnetic field. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM. Then the ECM uses this data to control fuel injection duration, injection timing and the VVT (Variable Valve Timing) system.
