Test 3: Front Wheel Speed Sensor Circuit Problem
- Turn ignition off. Raise and support vehicle. Disconnect ABS control unit harness connector. Set DVOM to AC scale. Rotate front wheel and measure voltage between ABS control unit connector. If DTC 5 is present, measure voltage between terminals No. 4 and No. 22 (No. 5 on FWD). If DTC 6 is present, measure voltage between terminals No. 11 and 21. See Figure . Voltage should be .20-.30 volt (AC). If voltage is as specified, replace ABS control unit. If voltage is not specified, go to next step.
- Ensure ABS control unit connector is disconnected. If DTC 5 is present, measure resistance between ground and terminal No. 22 (No. 5 on FWD). If DTC 6 is present, measure resistance between ground and terminal No. 21. Resistance should be infinite. If resistance is as specified, repair wiring. If resistance is not as specified, go to next step.
- Disconnect front wheel sensor harness connector. Using ohmmeter, check resistance between front sensor connector terminals. If resistance is not 800-1300 ohms, replace wheel sensor. Check resistance between front sensor connector terminal No. 1 and ground. If resistance is less than 1 megohm, replace wheel sensor.
- Inspect wheel speed sensor air gap. See WHEEL SPEED SENSOR AIR GAP under ADJUSTMENTS. Adjust as necessary. Ensure sensor(s) and tone wheel(s) are not damaged. If sensor adjustment is within specifications and no damage is present, repair wiring.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
