Hyundai Santa Fe (TM): Engine Control System / Camshaft Position Sensor (CMPS). Description and operation

Hyundai Santa Fe (TM) 2019-2023 Service and Repair Manual / Engine Control/Fuel System / Engine Control System / Camshaft Position Sensor (CMPS). Description and operation

Description
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element.
It is related with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which the CKPS can't detect.
The CMPS is installed on engine head cover and uses a target wheel installed on the camshaft. The Cam Position sensor is a hall-effect type sensor. As the target wheel passes the Hall sensor, the magnetic field changes in the sensor. The sensor then switches a signal which creates a square wave.

    Inspection 1. Check the signal waveform of the CMPS and CKPS using the diagnostic tool. Specification : Refer to "DTC Diagnostic Guide" Removal    • Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.
