Kia Sportage: Crankshaft Position Sensor (CKPS)

Description and Operation

 Description

Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the engine control system. If there is no CKPS signal input, the engine may stop because of CKPS signal missing. This sensor is installed on the cylinder block or the transaxle housing and generates alternating current by magnetic flux field which is made by the sensor and the target wheel when engine runs.

The target wheel consists of 58 slots and 2 missing slots on 360 degrees CA (Crank Angle).

Repair procedures

Inspection

1. Check the signal waveform of the CMPS and CKPS using the GDS.

Specification: Refer to "Wave Form"

Removal

1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.

2. Disconnect the crankshaft position sensor connector (A).

3. Remove the protector (A).

4. Remove the installation bolt (A), and then remove the crankshaft position sensor.

Installation

CAUTION

• Install the component with the specified torques.
• Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

CAUTION

• Apply the engine oil to the O-ring.

CAUTION

• Insert the sensor in the installation hole and be careful not to damage.

1. Installation is reverse of removal.

Crankshaft position sensor installation bolt: 9.8 ~ 11.8 N.m (1.0 ~1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

Crankshaft position sensor protector installation bolt (M6): 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

Crankshaft position sensor protector installation bolt (M8): 18.6 ~ 23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)

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 GDS.

Specification: Refer to "Wave Form"

Removal

WARNING

• 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 bums.

[Bank 1 / Intake]

1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.

2. Disconnect the camshaft position sensor connector (A).

З. Remove the installation bolt (B), and then remove the sensor.

[Bank 1 / Exhaust]

1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.

2. Remove the heater protect cover (Refer to "Intake And Exhaust System" in EM group).

3. Disconnect the camshaft position sensor connector (A).

4. Remove the hanger and the protector.

5. Remove the installation bolt, and then remove the sensor.

Installation

CAUTION

• Install the component with the specified torques.
• Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

CAUTION

• Apply the engine oil to the O-ring.

CAUTION

• Insert the sensor in the installation hole and be careful not to damage.

CAUTION

• Be careful not to damage the sensor housing and the connector.
• Be careful not to damage the O-ring.

1. Installation is reverse of removal.
