C1276/76 - Abnormal Change in Output Signal of Front Speed Sensor LH (Test Mode DTC)
DESCRIPTION
The speed sensor detects wheel speed and transmits the appropriate signals to the skid control ECU. These signals are used for control of the ABS
system. Each of the front and rear rotors has 48 serrations.
When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces 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 skid control ECU to detect the speed of each wheel.
DTCs C1271/71, C1272/72, C1275/75 and C1276/76 are output only in the Test Mode.
HINT
DTC No.C0200/31 and C1235/35 are for the front speed sensor RH.
DTC No.C0205/32 and C1236/36 are for the front speed sensor LH.
