P0A44Drive Motor A Position Sensor Circuit Overspeed
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0A44 reports that the speed derived from the motor A resolver is above the highest speed the motor may run. Mitsubishi uses it on the 2023 Outlander PHEV front motor: set at 15,500 rpm or more for 0.5 s with module supply above 8 V, judged only when the position sensor itself is fault-free; the guided fix after other codes are ruled out is a new front motor. GM covers the same check under its own code P1B0D (above 11,500 rpm, Type A) instead of P0A44. A true overspeed can come from a slipping drivetrain or a mechanical fault; a false one from a corrupted speed signal. P0A3F to P0A43 cover the sensor circuit. The system cuts motor torque to protect the rotor.
- What you may notice
- Electric drive torque cut during acceleration or high speed
- Hybrid/EV system warning and MIL
- Reduced top speed in limp mode
- Likely causes
- PossibleMechanical fault in the front motor or its drivetrain (Mitsubishi replaces the motor)
- PossibleReal overspeed from wheel spin or a slipping coupling
- PossibleDisturbed resolver signal producing a false speed value
- RareMotor control module calculating speed incorrectly
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
