Crankshaft Position Sensor: Testing and Inspection
CRANKSHAFT POSITION SENSORINSPECTION
1. CRANKSHAFT POSITION SENSOR (METHOD WITH CIRCUIT TESTER)
Measure the resistance between crankshaft position sensor terminals.
2. CRANKSHAFT POSITION SENSOR (METHOD WITH OSCILLOSCOPE)
1. Prepare an oscilloscope.
2. Disconnect the ground cable from battery.
3. Remove the front pillar lower trim and console side panel lower RH of passenger's side.
4. Detach the floor mat of passenger's seat.
5. Remove the protect cover.
6. Remove the ECM from vehicle.
7. Connect the probe to ECM connector.
8. Start the engine and let it idle.
9. Check the pattern is the same as the waveform and voltage shown below.
10. After inspection, install the related parts in the reverse order of removal.
Tightening torque: 7.5 N.m (0.8 kgf.m, 5.5 ft.lb)
3. OTHER INSPECTIONS
Check that the crankshaft position sensor has no deformation, cracks or other damages
