Description and operation
Camshaft Position Sensor (CMPS) is a hall sensor, which 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 cannot be detected by the CKPS.
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 in the sensor changes. The sensor
then sends off a signal which creates a square wave which is used for precisely
detecting the location of each cylinder to control the independent sequential injection
of each cylinder.

Repair procedures
| 1. |
Check the signal waveform of the CMPS and CKPS using the KDS.

Specification: Refer to “Wave Form”
|
|
| • |
DON’T remove the camshaft position sensor while the engine is
running or right after engine is turned off. The part and engine
oil is hot and can cause burns.
|
|
| 1. |
Switch "OFF" the ignition and disconnect the negative (-) battery terminal.
|
| 2. |
Disconnect the camshaft position sensor connector (A).
|
| 3. |
Remove the camshaft position sensor after loosening the mounting bolt
(B).
