Component Tests and General Diagnostics
CAMSHAFT POSITION (CMP) SENSOR INSPECTIONNOTE: Perform the following inspection only when directed.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the CMP sensor connector.
3. Measure the resistance between the CMP sensor terminals A and B using an ohmmeter.
- If the CMP sensor is okay, but the PID value is out of specification, perform the "Circuit Open/Short Inspection".
- If not as specified, replace the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION.)
Specification: 467 - 571 ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
2. Inspect the following harness for open or short circuit. (Continuity check).
Open circuit
- CMP sensor (RH) terminal A (harness-side) and PCM terminal 85 (harness-side)
- CMP sensor (RH) terminal B (harness-side) and PCM terminal 86 (harness-side)
- CMP sensor (LH) terminal A (harness-side) and PCM terminal 58 (harness-side)
- CMP sensor (LH) terminal B (harness-side) and PCM terminal 59 (harness-side)
Short circuit
- CMP sensor (RH) terminal A (harness-side) and power supply
- CMP sensor (RH) terminal A (harness-side) and body GND
- CMP sensor (RH) terminal B (harness-side) and power supply
- CMP sensor (RH) terminal B (harness-side) and body GND
- CMP sensor (LH) terminal A (harness-side) and power supply
- CMP sensor (LH) terminal A (harness-side) and body GND
- CMP sensor (LH) terminal B (harness-side) and power supply
- CMP sensor (LH) terminal B (harness-side) and body GND
