P0D9CBattery Charger Coupler Temperature Sensor A Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D9C is stored when the signal of coupler temperature sensor A climbs above its valid window, the typical result of an open sensor loop, an unplugged connector or a short to a supply voltage. Read as temperature, a high signal means cold for an NTC but hot for the resistive PTC and Pt 1000 elements found in CCS inlets from Phoenix Contact, which is why an interrupted Pt 1000 wire can look like a contact far above the +90 °C shutdown limit and stop charging at once. Bentley's TPI 2075291/1 for the 2024 Bentayga Hybrid confirms that P0D9C is the high fault, although the on-board charger (address 00C6) shows the text of the low fault; the diagnostic path must follow the code number. Bentley gives no thresholds. Unlike true overtemperature (P0E5F), nothing is actually hot here; the circuit is at fault. Its low counterpart is P0D9B.
- What you may notice
- Charging stops immediately or does not start
- Charging system fault message
- Fault stored as intermittent or static in the charger
- Likely causes
- LikelyOpen sensor wire or connector at the inlet or charger
- PossibleSensor signal wire shorted to a supply voltage
- PossibleTemperature element open inside the inlet
- RareDiagnosis misled by swapped fault texts in the charger (Bentley)
