P0113 on a Ford: Causes, Fixes & Repair Cost
🟢 Low severity · drivable
Safe to drive — the engine just reads intake air temperature wrong, which may cause slightly rich running.
What P0113 means on a Ford
On a Ford, P0113 means the intake air temperature (IAT) sensor is sending a high-voltage, open-circuit signal. Depending on the model, the IAT sensor is either separate in the intake duct or built into the mass air flow sensor. The engine may run slightly rich until it is fixed.
Is P0113 common on Fords?
P0113 is fairly common on Fords, where the IAT sensor or its wiring wears with age. Wiring chafing and connector problems show up on trucks and SUVs that see heavy use, and dirty sensor elements are a factor on higher-mileage engines. It is a sensor fault, not an engine failure.
Commonly reported on: F-150, Escape, Focus, Explorer.
