What P2DAE means
P2DAE means the sensor B voltage has fallen below the lowest value a healthy sensor can deliver. Winding probes are mostly NTC thermistors whose resistance collapses as they heat – Thinking Electronic quotes roughly 0.46 kOhm at 180 °C for its stator probes – so with the usual pull-up circuit a near-zero voltage would read as an impossibly hot winding. In practice it points to a short: signal lead to ground or to the motor housing, a shorted thermistor, or a lead pinched during assembly. On the 2023 Outlander PHEV, Mitsubishi's own code P3053 catches its V-phase probe when the signal stays at or under 0.1 V for half a second, provided the power drive unit has at least 8 V. No manufacturer documents P2DAE publicly. P2DAF is the opposite fault; real overheating would be P0A2F.
P2DAE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 12 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2DAE
- Hybrid system warning or check engine light
- Sensor B shows an extremely high fixed temperature in live data
- Electric drive power reduced
Common causes of P2DAE
- Most likelySensor B signal lead shorted to ground or motor housing
- PossibleThermistor shorted internally (often replaceable only with the motor)
- Less likelyLead pinched or chafed after work on the drive unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2DAE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| AE | The exact fault in that area. |
What to do next
- Note P2DAE and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2DAE
What does P2DAE mean?
P2DAE means "Drive Motor A Temperature Sensor B Circuit Low". P2DAE means the sensor B voltage has fallen below the lowest value a healthy sensor can deliver. It is a generic code, so it means the same on every make.
Is it safe to drive with P2DAE?
Drive gently and only to a workshop. With P2DAE the car can go into limp mode (reduced power) to protect itself.
Will P2DAE fail an emissions test?
Yes, it can. P2DAE is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2DAE to fix?
Difficulty: workshop only. A typical repair takes 1 to 12 hours of work. This is a job for a workshop.
Will P2DAE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
