Code C0205 Description
When the rotors rotate, the magnetic field emitted by the permanent magnet in the speed sensor generates AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.
What are the Possible Causes of the DTC C0205?
- Faulty Left Front Speed Sensor
- Left Front Speed Sensor harness is open or shorted
- Left Front Speed Sensor circuit poor electrical connection
- Left Front Speed Sensor rotor
- Sensor installation
- Brake actuator (skid control ECU)
