Lincoln Aviator · 2020–2022
Certain 2020-2022 Aviator PHEVs are included in Ford Customer Satisfaction Program 22P16. Ford states that if remote start is requested while the vehicle is connected to a charging cable, the cable is disconnected, and the vehicle is then driven, the engine may not start when needed. The vehicle remains limited to high-voltage battery power; when that battery is depleted, DTC P1A0C and Stop Safely Now can occur. Other loss-of-power or Stop Safely Now events require separate diagnosis.
Common Symptoms
- Engine does not start after remote start while plugged in and subsequent cord disconnection
- Vehicle operates only on high-voltage battery until depletion
- Stop Safely Now message
- DTC P1A0C
How to Fix
Have a Lincoln dealer check the VIN in OASIS for CSP 22P16. For an included vehicle, the dealer updates the PCM, ABS module, secondary on-board diagnostic modules, and battery energy control module to the latest levels at no charge within the program terms. If P1A0C or Stop Safely Now occurs after a different sequence, retain a full vehicle scan and diagnose that event independently rather than assuming 22P16. The program document states coverage through 8 years/100,000 miles from warranty start for affected VINs.
Owner tips & cautions
- TipPreserve the full scan and the exact remote-start, charging-cable, and drive sequence; P1A0C after the CSP-defined sequence is much more specific than Stop Safely Now by itself.
- WarningDo not treat every PHEV loss-of-power event as CSP 22P16; other high-voltage, charging, or powertrain faults need their own diagnosis.

Frequently asked questions
What does P1A0C mean?
P1A0C stands for "Hybrid Powertrain Control Module - Engine Disabled." Manufacturer-specific code used by Ford (and Lincoln) hybrid vehicles. The hybrid powertrain control system has commanded the gasoline engine to be disabled, meaning the hybrid controller detected a condition it considers unsafe or out of range and shut the engine down rather than let it run. This is usually a secondary or consequence code - it reports the shutdown, not the underlying reason - so the other stored codes and the hybrid system's own fault records are what actually point to the cause. Symptoms include a stop-safely-now or wrench warning, no engine start, stalling, or the vehicle refusing to move.
What are the most common causes of P1A0C?
The most common causes of P1A0C are: Another stored powertrain or hybrid fault that the hybrid controller responds to by disabling the engine, High-voltage battery fault or a weak/failed cell module reported by the battery energy control module, Wiring, connector, or high-voltage interlock loop fault in the hybrid system, High-voltage battery cooling problem causing an over-temperature shutdown, Hybrid powertrain control module fault or software calibration needing an update. The specific cause varies by vehicle.
How much does it cost to fix P1A0C?
Repair costs vary widely depending on the root cause and vehicle.
