Description and operation
The
Camshaft Position Sensor (CMPS) is used for detecting the camshaft
position by using a hall element, and is also called the hall sensor.
Installed on engine head cover, the CMPS uses a target wheel installed
on the camshaft to determine the position of each piston that cannot be
detected by CKPS. It is equipped with a hall-effect IC whose output
voltage changes when magnetic field is applied to the IC with current
flow. Hence, the sequential injection of each cylinder is possible with
CMPS signal.

Repair procedures
| 1. | Check the signal waveform of the CMPS and CKPS using the KDS.
Specification: Refer to “Wave Form” |
|
DO
NOT remove the camshaft position sensor while the engine is running or
immediately after turning off the engine as the part and engine oil are
hot and can cause burns. |
| 1. | Turn the ignition switch OFF and disconnect the battery negative (-) terminal. |
| 2. | Remove the air cleaner.
(Refer to Engine Mechanical System - “Air Cleaner”)
|
| 3. | Disconnect the camshaft position sensor connector (A). |
| 4. | Remove the sensor (B) by loosening the mounting bolt.
