P1901 Ax acceleration sensor plausibility
Functional diagnosis:
•
Faulty sensor/Signal not valid
Troubleshooting:
With faulty sensor, the component inside the control unit is damaged and replacement of the control
unit is recommended. With signal not valid, the sensor has generated a signal out of range that is still
sent to the injection control unit together with the relevant error.
NOTE: The instrument panel does not indicate the presence of this error even in the ATT status.
NOTE
THIS ERROR DISABLES THE TRACTION CONTROL.
