DTC P0365: Camshaft Position Sensor "B" Circuit (Bank 1) [01/2019 - 03/2019]: Description
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
The cam 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 cam position 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 cam 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 and fuel injection timing.
