C059CBrake Pressure Sensor C Missing Calibration
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- For pressure sensor C the module finds no confirmed calibration record. Such a record usually holds the zero offset and a status flag written on the assembly line or by the scan tool. No maker documents C059C publicly. Related checks are published: GM's 2019 EBCM reads only that status flag for its master cylinder sensor (C0560) 500 ms after wake-up, Type A with MIL, and Ford hybrids compare checksum and sensor ID between sensor and module (150 or 70 ms). GM's 2016 hybrid controller uses C0571–C0574 for a master cylinder sensor but files its calibration fault under C0560, so letters in calibration codes need not match circuit codes. Saab names module and modulator replacement as reasons to recalibrate with the brake released and the car secured.
