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. If resistance is not 800-1200 ohms, 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 WHEEL SPEED SENSOR TERMINAL IDENTIFICATION and WHEEL SPEED SENSOR RESISTANCE SPECIFICATIONS tables. If resistance is not within specification, repair harness between ECU and wheel speed sensor.
