Right Rear Wheel Speed Sensor Circuit Frequency too High
Description:
Ignition ON.Ignition voltage is greater than 10 volts.The brake pedal is not pressed.Two or three other wheel speeds are greater than 0 km or h.
Cause:
C0035 04 - C0050 04, C0035 0E - C0050 0E, C1232 - C1235, or C1207 - C1210A short to voltage,short to ground or an open or high resistance is detected on a wheel speed sensor circuit.C0035 26 - C0050 26, C0035 27 - C0050 27, C0035 1F - C0050 1F,C1221 - C1224, C1225 - C1228, or C1221 - C1224A missing wheel speed sensor signal.An erratic signal output of the wheel speed sensor is detected.The EBCM detects a change in wheel speed that exceeds 20 km or h (12 mph) between two 10 millisecond wheel speed samples.Conditions for Setting the DTCA short to voltage,short to ground or an open or high resistance is detected on a wheel speed sensor circuit.A missing wheel speed sensor signalAn erratic signal output of the wheel speed sensor is detected.The EBCM detects a change in wheel speed that exceeds 20 km or h (12 mph) between two 10 millisecond wheel speed samples.
