What does code P087D mean?

Q: What does code P087D mean?

Clutch Position Sensor B Circuit High. P087D indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the signal circuit for clutch position sensor B, which is typically a secondary or redundant clutch pedal position sensor used on manual or automated manual transmissions. The PCM expects the sensor's output to stay within a calibrated voltage range as the clutch pedal moves, and a sustained high reading tells the module that the circuit is open, shorted to voltage, or that the sensor has failed.
