Camshaft Position Sensor: Testing and Inspection
CAMSHAFT POSITION (CMP) SENSOR INSPECTION
NOTE: 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.
Specification: 467 - 571 ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
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
-
