Component Tests and General Diagnostics
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 2 and 28 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 Breakout BOX) with the PCM disconnected.
3. Tighten the connector attaching bolt.
Tightening torque: 3.0 - 5.4 N.m {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 28
- CMP sensor terminal B (harness-side) and 104 Pin breakout box terminal 2
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
