Component Tests and General Diagnostics
Air Gap InspectionNOTE: Perform the following test only when directed.
1. Verify that the CKP sensor is installed properly.
2. Measure the air gap between the plate teeth and the CKP sensor using a feeler gauge.
- If not as specified, adjust the CKP sensor or inspect the plate teeth for being twisted and/or chipped.
- If any of the plate teeth is twisted and/or chipped, replace the plate.
Specification: 0.6 - 1.5 mm {0.020 - 0.059 in}
Resistance Inspection
1. Disconnect the CKP sensor connector.
2. Measure the resistance between CKP sensor terminals A and B using an ohmmeter.
- If not as specified, replace the CKP sensor.
- If CKP sensor resistance is okay, but PID value or PCM terminal 21 and 22 voltage are out of specification, carry out the "Circuit Open/Short Inspection".
Specification: Approx. 550 Ohms
Circuit Open/Short Inspection
1. Remove the PCM.
2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.
Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}
4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST (104 Pin Breakout Box) terminals with ohmmeter leads.
- If there is an open or short circuit, repair or replace wiring harnesses.
- If there is no open or short circuit, replace the CKP sensor.
Open circuit
- CKP signal (+) circuit (CKP sensor connector terminal A and PCM connector terminal 21)
- CKP signal (-) circuit (CKP sensor connector terminal B and PCM connector terminal 22)
Short circuit
- CKP signal (+) circuit (CKP sensor connector terminal A and PCM connector 21 to GND)
- CKP signal (-) circuit (CKP sensor connector terminal B and PCM connector terminal 22)
5. Reconnect the CKP sensor connector.
