Code 9, Open Wheel Speed Sensor Circuit

  1. Turn ignition off. Disconnect speed sensor connector. Measure resistance across speed sensor terminals. If resistance is greater than 2000 ohms, replace speed sensor.
  2. If resistance is 1000-2000 ohms, disconnect RWAL EBCM connector. Reconnect speed sensor connector. Measure resistance between EBCM terminals No. 16 (Orange wire) and 17 (White wire). If resistance is greater than 2000 ohms, repair open in speed sensor wiring. If resistance is 1000-2000 ohms, replace RWAL EBCM. See RWAL ELECTRONIC CONTROL MODULE  under REMOVAL & INSTALLATION.
