DTC 9: Open Wheel Speed Sensor Circuit
- Turn ignition off. Disconnect wheel speed sensor connector. Measure resistance across wheel speed sensor terminals. See Figure. If resistance is more than 2000 ohms, replace wheel speed sensor.
- If resistance is 1000-2000 ohms, disconnect RWAL ECM connector. Reconnect speed sensor connector. Measure resistance between RWAL ECM terminals No. 9 and 10. If resistance is more than 2000 ohms, repair open in speed sensor wiring. If resistance is 1000-2000 ohms, replace RWAL ECM.
