C0230Brake Pedal Position Sensor Circuit
- Generic OBD-II code · Chassis
- How the car detects it
- C0230 is in none of the accessible J2012 tables and in no NHTSA bulletin or manufacturer index, so it cannot be traced to a vehicle. The title points to the electrical side of a brake pedal position sensor: a supply, signal or ground line that is open or shorted, so the reading falls outside the band the module accepts. GM's patent for a two-output resistive sensor names these out-of-range low and high conditions as the standard on-board check before it adds a test for faults within the range. Bosch's Hall-type PWG sensor delivers two independent PWM outputs; if one disappears or both disagree, the controller can tell a wiring fault from a real pedal movement. Expected effects are stop lamp or cruise control trouble, a lit warning lamp and, on hybrids, limited brake blending.
