Inspection of Resistance

1. Disconnect the CKP sensor connector.




2. Measure the resistance between the CKP sensor terminals A and B using an ohmmeter.

Specification: Approx. 550 ohms

- 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".

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 terminal 21 to GND)
- CKP signal circuit (CKP sensor connector terminal B and PCM connector terminal 22 to GND)

5. Reconnect the CKP sensor connector.
