What P0A43 means
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.
P0A43 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0A43
- Hybrid system warning or MIL that comes and goes
- Brief loss of propulsion, normal again after restart
- Code stored as history without current symptoms
Common causes of P0A43
- Most likelyLoose or spread terminal in the resolver connector, losing contact under vibration
- PossibleHybrid control or inverter software needing an update (Stellantis)
- PossibleChafed resolver wiring making intermittent contact
- Less likelyIntermittent fault in the power inverter module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A43 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| 43 | The exact fault in that area. |
What to do next
- Note P0A43 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 P0A43
What does P0A43 mean?
P0A43 means "Drive Motor A Position Sensor Circuit Intermittent". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A43?
Drive gently and only to a workshop. With P0A43 the car can go into limp mode (reduced power) to protect itself.
Will P0A43 fail an emissions test?
Yes, it can. P0A43 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 P0A43 to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0A43 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
