Speed Sensor Test: Rear

Remove seat cushion and side seatback. Disconnect speed sensor connector. Measure resistance between speed sensor terminals. If resistance is not 800-2050 ohms, replace speed sensor. If resistance is 800-2050 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.
