Sensor Resistance Test
- Before testing sensor resistance, ensure no foreign material has adhered to pole piece at wheel speed sensor tip. Sensor pole can become magnetized and pick up foreign material. Check wheel sensor pole piece for damage. If damaged, replace sensor.
- Disconnect sensor connector. Inspect sensor wiring harness for broken and pinched wires. Repair or replace as necessary. Using an ohmmeter, measure sensor resistance at wiring connector. Refer to the WHEEL SPEED SENSOR RESISTANCE SPECIFICATIONS
table. If resistance is not within specification, replace sensor. If resistance is within specification, go to next step.

- Connect speed sensor wiring connector. Disconnect ECU harness connector. Measure resistance between appropriate wheel speed sensor terminals. See the WHEEL SPEED SENSOR TERMINAL ID
table and the WHEEL SPEED SENSOR RESISTANCE SPECIFICATIONS
tables. If resistance is not within specification, repair harness between ECU and wheel speed sensor.
