What does code P25C6 mean?

Q: What does code P25C6 mean?

Brake Booster Temperature Sensor A Circuit Low. P25C6 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the signal circuit of the brake booster temperature sensor, which is used to monitor the temperature of the brake booster for safety and performance. The sensor typically produces a voltage that rises with temperature, so a low reading tells the PCM that the sensor circuit is shorted to ground, the sensor has failed, or the wiring is damaged.
