3360363 - Z63 SPEED SENSORS ERROR PLAUSIBILITY ERROR

The diagnostic equipment signals one or more of the following errors: C1201 ADX speed sensor, plausibility error, C1206 ASX speed sensor, plausibility error, C1211 PDX speed sensor, plausibility error and/or C1216 PSX speed sensor, plausibility error
This error is signalled if the control unit does not detect problems of an electrical nature, but the speed of one of the wheels (transmitted by the sensor) is not plausible
Results of the tests
1SENSOR CHECKAll OKProblems metOperation
Visually inspect the state of the sensors involved in the error (front and/or rear, right and/or left).

In particular, check:

  • that there are not metal shavings in the magnetic tracks for the flywheels.
  • that the sensor has been correctly fitted
  • that the sensor does not show signs of abrasion or distortion
