C0215 LEXUS, SCION, TOYOTA: LEFT REAR WHEEL SPEED SENSOR SIGNAL MALFUNCTION

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.
