C059DBrake Pressure Sensor D Missing Calibration

  • Generic OBD-II code · Chassis
  • Can trigger limp mode
How the car detects it
C059D flags missing calibration data for a fourth hydraulic pressure sensor. No manufacturer publishes this code. Where the letter D appears elsewhere, GM's 2016 hybrid brake controller uses it for the rear-left wheel pressure sensor (C0575–C0578), yet reports that sensor's calibration fault as C059B; the letters of the calibration codes therefore follow each maker's own list. Mitsubishi's 2023 Outlander PHEV has a comparable fault without SAE number, C105E-92 for an uncalibrated pressure sensor, detected within 1 s, and tells technicians to clear a merely stored code instead of replacing the unit. A Bosch patent describes resetting an offset fault only after a successful check while driving. Practically, the module limits ABS/ESC functions until the scan tool calibration has passed.
What you may notice
  • ABS and ESC warning lamps on
  • Brake pressure based functions such as hill hold or brake blending limited
Likely causes
  • LikelyCalibration of the sensor not done after hydraulic unit or module replacement
  • PossibleCode stored from an earlier event, sensor already calibrated
  • RareBrake module losing calibration data in its memory
