CRANKSHAFT POSITION (CKP) SENSOR INSPECTION

NOTE: Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart.

Resistance Inspection
1. Disconnect the CKP sensor connector.
2. Measure the resistance between CKP sensor connector terminals A and B.
- 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", and repair or replace the malfunctioning part.

Resistance
400 - 550 Ohms

Circuit Open/Short Inspection




1. Disconnect the PCM connector.
2. Inspect the following wiring harnesses for an open or short circuit. (Continuity inspection)

Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
- CKP sensor terminal A and PCM terminal 2Y
- CKP sensor terminal B and PCM terminal 2Z

Short circuit
- If there is continuity, there is a short circuit. Repair or replace the wiring harness.
- CKP sensor terminal A and power supply
- CKP sensor terminal A and body GND
- CKP sensor terminal B and power supply
- CKP sensor terminal B and body GND
