P1A0C on 2020-2022 Lincoln Aviator — Hybrid Powertrain Control Module - Engine Disabled
1 vehicles · 1 makes
Most Reported On
P1A0C is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2020-2022 Lincoln Aviator.
