Wheel Speed Sensor Circuits

1. Ensure ignition switched off
2. Disconnect ECU multi-plug
3. Connect ohmmeter between harness multi-plug terminals listed below:
o LHF: 7 and 25
o RHF: 5 and 23
o LHR: 4 and 22
o RHR: 6 and 24
4. Resistance should be 900 to 1400 ohms
5. If resistance not as specified:
o Disconnect the appropriate wheel sensor from the car loom.
o Measure resistance across wheel sensor at plug on end of sensor.
o If outside above range, replace wheel sensor.
o If OK, check wiring between sensor connection and ECU.
