P0364 code meaning
DC/AC Converter Control Module Control Circuit Range/Performance
What P0364 means
P0364 reports that the control circuit between the engine module and the control module of a DC/AC converter (inverter) behaves implausibly – the command or enable line is present but its signal does not fit what the engine module expects. The code is a late assignment in the P03xx block; the other DC/AC converter codes sit in the P2DAx range (P2DA8–P2DAB). Ford uses it on the 2021 F-150. On the 3.5 L PowerBoost hybrid, whose DC/AC converter module A feeds the Pro Power Onboard sockets, bulletin 21-2229 links P0364 in the PCM to a disabled Pro Power Onboard and a 'Pro Power Onboard Service Required' message; the cause was software parameters in the inverter and the PCM, fixed by reprogramming both. Bulletin 21-2087 lists P0364 among the codes that 3.5 L EcoBoost trucks built up to 2 March 2021 stored with the MIL on, cured by a PCM update alone. Without such a bulletin, check the enable and command wiring between PCM and inverter and the software levels of both modules.
P0364 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0364
- Warning lamp depending on the manufacturer
- Converter function restricted (for example power socket or hybrid drive)
Common causes of P0364
- PossibleControl or enable line to the converter module disturbed (connector, wiring)
- PossibleConverter control module faulty internally
- Less likelySoftware of the modules involved
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0364 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3 | Area: ignition system or misfire. |
| 64 | The exact fault in that area. |
What to do next
- Note P0364 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 P0364
What does P0364 mean?
P0364 means "DC/AC Converter Control Module Control Circuit Range/Performance". P0364 reports that the control circuit between the engine module and the control module of a DC/AC converter (inverter) behaves implausibly – the command or enable line is present but its signal does not fit what the engine module expects. It is a generic code, so it means the same on every make.
Is it safe to drive with P0364?
P0364 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0364 fail an emissions test?
P0364 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0364 to fix?
Difficulty: hard. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P0364 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
