Code 11, Shorted Wheel Speed Sensor
- Turn ignition off. Disconnect speed sensor connector and measure resistance across sensor terminals. If resistance is less than 1000 ohms, replace speed sensor.
- If resistance is 1000-2000 ohms, disconnect RWAL ECM connector. Leave speed sensor disconnected. Measure resistance between ECM terminal No. 16 and ground. See Figure . Repair short to ground in Orange wire if resistance is less than 20 k/ohms.
- If resistance is more than 20 k/ohms, measure resistance between RWAL ECM terminals No. 16 and 17. If resistance is more than 20 k/ohms, replace RWAL ECM. Repair short between Orange and White wires in speed sensor harness if resistance is less than 20 k/ohms.
