C1236

DTC C1236/36 Foreign Object is Attached on Tip of Front Speed Sensor LH

DESCRIPTION

DTC Detection Condition:

The speed sensor detects wheel speed and transmits the appropriate signals to the ECU. These signals are used for control of the ABS.

Each of the front and rear rotors have 48 serrations. When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor produces 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.

HINT:
- DTCs C0200/31 and C1235/35 are for the front speed sensor RH.
- DTCs C0205/32 and C1236/36 are for the front speed sensor LH.
