P271DPark Pawl Position Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P271D is logged when the signal of park pawl position sensor B sits above its upper limit. Electrically this is the mirror image of P271C: an interrupted sensor ground, an open signal line pulled up inside the controller, or contact with a supply wire. No manufacturer documents P271D publicly, so neither thresholds nor debounce times are known; Ford's recall 26V688 for the park module of the HF55 hybrid transmission is the only published case in this sensor family and involves sensor A. Because the pawl decides whether the car can roll away, controllers treat any doubt about its position conservatively. Expect a shift system warning and checks of wiring and connector at the actuator before the module itself is replaced.
