DTC P0365-11: Camshaft Position Sensor "B" Bank 1 Circuit Short to Ground; DTC P0365-15: Camshaft Position Sensor "B" Bank 1 Circuit Short to Battery or Open; DTC P0390-11: Camshaft Position Sensor "B" Bank 2 Circuit Short to Ground; DTC P0390-15: Camshaft Position Sensor "B" Bank 2 Circuit Short to Battery or Open [12/2019 - 10/2022]: Description
The VVT sensor (for exhaust camshaft) (EV1, EV2 signal) consists of a magnet and MRE (Magneto Resistance Element).
The exhaust camshaft has a timing rotor for the VVT sensor. When the exhaust 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 VVT 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 Variable Valve Timing (VVT) system.
