P2DB2Drive Motor A Temperature Sensor C 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
- P2DB2 flags a sensor C reading that is electrically valid but disagrees with what the motor should show. With three probes a cold-soak comparison is the natural test: Mitsubishi checks its W-phase sensor (sensor 3, own code P3057) on the 2023 Outlander PHEV once per driving cycle after more than 90 minutes off, inverter switched off, and rejects it when it lies over 26 °C away from the U-phase reading for 0.8 s or longer; the V-phase check runs continuously instead. CARB asks for two-sided rationality checks where feasible. A UAES patent also compares a stator probe with coolant and power-switch temperatures after a long stop. No manufacturer documents P2DB2. Thermistor drift, a poor contact or a probe that has lost touch with its winding are typical causes.
- What you may notice
- Hybrid system warning or check engine light
- Sensor C stands well apart from the other motor sensors after a cold start
- No noticeable driving change in many cases
- Likely causes
- LikelySensor C thermistor drifted from its resistance curve
- PossibleExtra resistance at a corroded or worn terminal
- RareProbe loose on its phase winding
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
