P2DB3Drive Motor A Temperature Sensor C Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2DB3 sets when the sensor C voltage drops below its valid floor. For an NTC probe this would stand for a temperature far beyond any real winding heat, so a short is much more likely than a genuine hot spot: signal lead to ground or motor housing, insulation damaged inside the stator, or a thermistor shorted internally. Mitsubishi, which reads its W-phase coil probe as sensor 3 on the 2023 Outlander PHEV, uses its own code P3056 and the same floor as on the other phases: no more than 0.1 V over half a second. Thinking Electronic rates its stator probes for −40 to 200 °C and tests them at up to 2000 V AC, a reminder that the probe sits in the high-voltage winding. No manufacturer documents P2DB3. P2DB4 is the high side, P2DAE the same fault on sensor B.
- What you may notice
- Hybrid system warning and check engine light
- Sensor C reads extremely hot while the other sensors look normal
- Electric drive power reduced
- Likely causes
- LikelySensor C signal lead shorted to ground or motor housing
- PossibleProbe insulation damaged inside the stator
- PossibleThermistor shorted internally
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
