POST UPDATED IN June, 2023
C0215 Code failures by brands
Description of DTC code C0215
The Speed Sensor detects the speed of the wheels. This data is transmitted to the corresponding ECU, which uses it to control the ABS system. Each sensor has splined rotors, so as the rotor rotates, the magnetic field produced by the sensor’s magnet varies. The frequency of this AC voltage changes as a direct function of rotor speed. This frequency is used by the ECU to detect the speed of each wheel.
Storing DTC C0215 OBD2 occurs when a fault is discovered by the Left Rear Wheel Speed Sensor.
