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. |

Description
Knocking is a phenomenon characterized by undesirable vibration and noise and
can cause engine damage...
Other information:
Schematic Diagram
•
The ISG system is strongly networked with the power management.
•
In the event of battery replacement, disconnection of the battery
terminal or after changing the engine management system, the
reference data regarding the battery charge state and battery
condition can be lost...
Inspection
1.
Disconnect the key warning switch connector (A) and ignition switch
connector (B) from the steering column.
2.
Check for continuity between the terminals...
