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.
Speed Sensor Test: Front
Remove front fender lining. Disconnect speed sensor connector. Measure resistance between speed sensor terminals. If resistance is not 600-1800 ohms, replace speed sensor. If resistance is 600-1800 ohms, measure resistance between chassis ground and each speed sensor terminal. If resistance is infinite (no continuity), speed sensor is okay. If resistance is not infinite (continuity), replace speed sensor.
