Wastegate Position Sensor Calibration Error

on 2015 Jeep Cherokee 3.2L V6 · AWD

What this code means

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

  1. Read wastegate position sensor raw values
  2. Perform sensor calibration procedure per manufacturer
  3. Compare commanded vs actual wastegate position
  4. Check sensor mounting for play
  5. Inspect sensor for heat damage

Repair notes

Perform wastegate position sensor calibration with manufacturer scan tool. Replace sensor if calibration procedure fails.
