DTC Code DTC Name
C0210/33 Rear Speed Sensor RH Circuit
C0215/34 Rear Speed Sensor LH Circuit
C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC)
C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC)
C1332/38 Right Rear Speed Sensor Circuit
C1333/39 Left Rear Speed Sensor Circuit

DESCRIPTION

The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system.

Speed sensor rotors have rows of alternating N and S magnetic poles (for 2WD) or 48 serrations (for AWD). The hall IC type speed sensor use the frequency of output pulses to detect the vehicle speed. Because the sensor outputs digital pulses, it can detect vehicle speeds even when the vehicle is nearly stationary.

DTCs C1273/73 and C1274/74 will be cleared when the speed sensor sends a vehicle speed signal or when Test Mode ends. DTCs C1273/73 and C1274/74 are output only in Test Mode.

INSPECTION PROCEDURE

PROCEDURE


  1. READ VALUE USING GTS (REAR SPEED SENSOR)


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Select the Data List on the GTS Click here.

      ABS/VSC/TRC
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      RR Wheel Speed Rear wheel speed sensor RH reading / Min.: 0 km/h (0 mph), Max.: 326 km/h (202 mph) Vehicle stopped: 0 km/h (0 mph) When driving at constant speed: No large fluctuations
      RL Wheel Speed Rear wheel speed sensor LH reading / Min.: 0 km/h (0 mph), Max.: 326 km/h (202 mph) Vehicle stopped: 0 km/h (0 mph) When driving at constant speed: No large fluctuations

    4. Check that the speed value output from the speed sensor displayed on the GTS.

      Tech Tips

      Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart Click here.

      OK
      The speed value output from the speed sensor displayed on the GTS is the similar speed as indicated on the speedometer.
