Wastegate Position Sensor Calibration Error
2010-2021 Fiat Uno 1.0L I4 Flex Fire Evo
Description
The electronic wastegate position sensor has lost its calibration reference. The PCM cannot accurately determine wastegate valve position.
Symptoms
- Check Engine Light
- Boost control reverts to safe mode
- Conservative boost levels applied
- Turbo response feels inconsistent
- May experience occasional overboost or underboost
Common Causes
- Sensor zero-point drift
- Sensor exposed to extreme heat
- Calibration data lost after battery disconnect
- Sensor magnet weakened
- Actuator mechanical play affecting position
Diagnostic Steps
- Read wastegate position sensor raw values
- Perform sensor calibration procedure per manufacturer
- Compare commanded vs actual wastegate position
- Check sensor mounting for play
- Inspect sensor for heat damage
Repair Notes
Perform wastegate position sensor calibration with manufacturer scan tool. Replace sensor if calibration procedure fails.
