P2DADDrive Motor A Temperature Sensor B Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2DAD covers a sensor B signal that stays inside the electrical window yet does not fit the situation. CARB asks for rationality checks on hybrid input components where feasible, logged under a code of their own apart from circuit and range faults. The obvious reference is a neighbouring probe: on the 2023 Outlander PHEV Mitsubishi compares its V-phase coil sensor (sensor 2, own code P3054) with the U-phase value after more than 90 minutes off and with the inverter switched off, and rejects it when the gap exceeds 26 °C for longer than 0.8 s. A UAES patent adds a running check: when winding current should heat the stator but the reading does not rise, the sensor is flagged as reading low. No manufacturer publishes P2DAD. Thermistor drift and extra contact resistance are the usual causes.
- What you may notice
- Hybrid system warning or check engine light
- Sensor B differs clearly from sensor A after the car has stood overnight
- Electric drive power limited in some situations
- Likely causes
- LikelySensor B thermistor drifted from its resistance curve
- PossibleAdded resistance at a worn or corroded terminal
- RareProbe no longer seated firmly against the winding
- RareFault in the reference value, e.g. sensor A or coolant temperature
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
