Hyundai i-30: Engine Control System / Camshaft Position Sensor (CMPS)
Description and operation
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.

Repair procedures
|
1. |
Check the signal waveform of the CMPS and CKPS using the diagnostic
tool.
|
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.
|
|
[Bank 1 / Intake]
|
1. |
Turn the ignition switch OFF and disconnect the battery negative (-)
terminal.
|
|
2. |
Disconnect the camshaft position sensor connector (A).
|
|
3. |
Remove the sensor after loosening the mounting bolt (B).
|
Tightening Torque :

[Bank 1 / Exhaust]
|
1. |
Turn the ignition switch OFF and disconnect the battery negative (-)
cable.
|
|
2. |
Disconnect the camshaft position sensor connector (A).
|
|
3. |
Remove the sensor after loosening the mounting bolt (B).
|
Tightening Torque :

|
Be careful not to damage the O-ring.
|
|
|
1. |
Install in the reverse order of removal.

The Parking Distance Warning
(Reverse/Forward) system assists
the driver during movement of the
vehicle by chiming if any object is
sensed within the distance of 100 cm
(39 inches) in front and 120 cm (47
inches) behind the vehicle.
This system is a supplemental system
that senses objects within the
range and location of the sensors, it
cannot detect objects in other areas
where sensors are not installed...
