C1032-RIGHT REAR WHEEL SPEED SENSOR SIGNAL ERRATIC PERFORMANCE





For a complete wiring diagram, refer to the Wiring Information.

NOTE: The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.

- When Monitored:
With the ignition on and no system under voltage or over voltage condition present.

- Set Condition:
If the measured wheel speed sensor feedback voltage is less than.304 of a volt, the sensor is considered open.

If the measured wheel speed sensor feedback voltage is greater than 1.39 volts, or if a sensor over current condition is detected, the sensor is considered shorted.

If a shorted or open condition is present for more than 100 msec, the DTC will set.
