Crankshaft Position Sensor: Testing and Inspection
Inspection of Air GapNOTE: Perform the following test only when directed.
Measure the air gap between each four projections of the plate behind the crankshaft pulley and the crankshaft position sensor using a feeler gauge.
- If not as specified, adjust the crankshaft position sensor air gap and inspect as follows:
Is any of the four projections of the plate behind the crankshaft pulley twisted or bent.
If not adjusted, replace the plate behind the crankshaft pulley crankshaft position sensor.
If crankshaft position sensor PID value is out of specification, perform the "Circuit Open/Short Inspection".
Specification: 0.5 - 1.5 mm {0.020 - 0.059 in.}
2. Reconnect the crankshaft position sensor connector.
Circuit Open/Short Inspection
Open circuit
If there is no continuity, the circuit is open. Repair or replace the harness.
- Crankshaft position circuit (Crankshaft position sensor connector terminal B and PCM connector terminal 2J.)
- Power circuit (Crankshaft position sensor connector terminal A and main relay terminal D through common connector.)
- Ground circuit (Crankshaft position sensor connector terminal C and PCM connector terminal 3C through common connector.)
Short circuit
If there is continuity, the circuit is shorted. Repair or replace the harness.
- Crankshaft position sensor connector terminal B and PCM connector terminal 2J circuit through common connector to ground.
- Crankshaft position sensor connector terminal A and main relay terminal D through common connector to ground.
