CAMSHAFT POSITION (CMP) SENSOR INSPECTIONResistance Inspection
1. Disconnect the CMP sensor connector.
2. Measure the resistance between CMP sensor terminals A and B using an ohmmeter.
Specification: 308-376 ohms
- If not as specified, replace the CMP sensor.
- If CMP sensor resistance is okay, but PID value or PCM terminals 85 and 86 voltages are out of specification, perform the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
1. Disconnect the PCM connector.(See PCM REMOVAL/INSTALLATION.)
2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.
Tightening torque: 3.0-5.4 Nm {30-56 kgf.cm, 27-48 in.lbf}
4. Inspect the following wiring harness for open or short circuit (Continuity check)
Open circuit
- If there is no continuity, the circuit is open Repair or replace the harness
- CMP sensor terminal A (harness-side) and 104 pin breakout box terminal 85
- CMP sensor terminal B (harness-side) and 104 Pin breakout box terminal 86
Short circuit
- If there is continuity, the circuit is shorted Repair or replace the harness
- CMP sensor terminal A (harness-side) and power supply
- CMP sensor terminal A (harness-side) and body ground
- CMP sensor terminal B (harness-side) and power supply
- CMP sensor terminal B (harness-side) and body ground
