Crankshaft Position Sensor: Testing and Inspection

CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [MZI-3.7]

NOTE: Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See HOW TO USE THIS MANUAL.)

Visual Inspection
1. Remove the CKP sensor.
2. Verify that there are no metal shavings on the CKP sensor.
3. Install the CKP sensor.

Resistance Inspection
1. Remove the CKP sensor connector.
2. Measure the resistance between the CKP sensor terminals.
- If not within the specification, replace the CKP sensor.
- If the monitor item status/specification (reference) is not within the specification, even though the resistance is within the specification, perform the "Circuit Open/Short Inspection".

CKP sensor resistance
250 - 1,000 ohms

Circuit Open/Short Inspection






1. Disconnect the PCM connector.
2. Inspect the following harness for open or short circuit. (Continuity check)

Open circuit
- CKP sensor terminal A and PCM terminal 2P
- CKP sensor terminal B and PCM terminal 2T

Short circuit
- CKP sensor terminal A and power supply
- CKP sensor terminal A and body ground
- CKP sensor terminal B and power supply
- CKP sensor terminal B and body ground
