Quick answer

Some 2024-2026 Explorer/Aviator/Police Interceptor Utility vehicles may exhibit an illuminated malfunction indicator (MIL) lamp with engine over-temperature warning in the message center and poor air conditioning (A/C) performance from the engine cooling fan not running. Diagnostic trouble codes (DTC) B3A1B, P0113, P0217, and/or P0480 may be stored in the powertrain control module (PCM). This may be due to poor engine compartment ground connections at G105, G107, G111 and/or G122. Refer to the Wiring Diagram (WD) > Grounds Cell 010 > Pages 2, 3, 7 and 8. Prior to any Workshop Manual (WSM) diagnostics, verify all listed grounds are tightened to 62 lb-in (7 Nm) to resolve this condition. If symptoms or DTCs return after all grounds are tightened, follow normal WSM diagnostics.

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
