Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wheel Speed Sensor
Check wheel speed sensor resistance. Front wheel speed sensor resistance should be 700-1100 ohms. Rear wheel speed sensor resistance should be 600-900 ohms. Check for open, short to ground or short between wheel speed sensor wires. Ensure installation gap between wheel speed sensor and wheel pulser is .016-.039" (0.4-1.0 mm). Check wheel pulser for chips or other damage.
