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. Remove the glove box lower cover.
3. Remove the lower inner trim of passenger's side.
4. Turn over the floor mat of passenger's seat.
5. Remove the protect cover.
6. Remove the nuts and bolts which hold the ECM to the bracket.
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.
