Component Tests and General Diagnostics
CRANKSHAFT POSITION (CKP) SENSOR INSPECTIONNOTE: Perform the following inspection only when directed.
Resistance Inspection
1. Disconnect the CKP sensor connector.
2. Measure the resistance between CKP sensor terminals A and B using an ohmmeter.
- If not as specified, replace the CKP sensor.
- If CKP sensor resistance is normal, but RPM PID value is out of specification, perform the "Circuit Open/Short Inspection".
Specification
400 - 550 ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Inspect the following wiring harnesses for open or short circuit. (Continuity check)
Open circuit
- If there is no continuity, there is an open circuit. Repairer replace the wiring harness.
- CKP sensor terminal A and PCM terminal 27*1, 2D*2
- CKP sensor terminal B and PCM terminal 1*1, 2G*2
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
