- If the rear speed sensor rotor needs to be replaced, replace it together with the rear axle hub and bearing assembly with rear
speed sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed Sensor/Service and
Repair/Rear Speed Sensor/Removal for 2WD).
- If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related
Diagnostic Procedures/Problem Symptoms Table.
C -- CHECK FOR INTERMITTENT PROBLEMS See: Accessories and Optional Equipment/Antitheft and Alarm
Systems/Diagrams/Diagnostic Aids/How To Troubleshoot ECU Controlled Systems/How To Proceed With Troubleshooting
B -- REPLACE REAR SPEED SENSOR AND REAR SPEED SENSOR ROTOR
A -- Continue to next step.
5. REPLACE REAR SPEED SENSOR
(a) Turn the engine switch off.
(b) Replace the rear speed sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed
Sensor/Service and Repair/Rear Speed Sensor/Removal.
NOTICE:
Check the speed sensor signal after replacement See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Test Mode Procedure.
NEXT -- Continue to next step.
6. RECONFIRM DTC
(a) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes.
(b) Start the engine.
(c) Drive the vehicle at a speed of 40 km/h (25 mph) or more for at least 60 seconds.
(d) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes.

Sensor RH Malfunction
DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for ABS control.
Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change when the rotors turn.
Each speed sensor detects that magnetic change and sends a pulse signal to the skid control ECU.
