P0A43Drive Motor A Position Sensor Circuit Intermittent
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0A43 is set when the motor A resolver signal drops out or jumps only briefly, so that neither a steady low, high nor a lasting loss is confirmed. Stellantis uses it on the Pacifica Hybrid: NHTSA files show P0A43-00 stored in the hybrid control processor next to P0A3F and P0A45, and a 2026 parts review tells dealers to check active bulletins and flash the hybrid control processor before ordering a new power inverter module. No public set threshold exists. GM's Bolt bulletin shows how a slightly spread connector terminal causes such short dropouts. P0A3F, P0A41 and P0A42 cover permanent faults. Expect a warning that may vanish after a restart, sometimes with a short loss of drive.
