P0113 — Intake Air Temperature High Input

P0113 is set when the ECM sees the intake air temperature sensor signal voltage above the calibrated maximum — typically a reading that would represent an unrealistically cold air temperature (often below −40 °F / −40 °C). This is the textbook fingerprint of an open circuit at the IAT sensor: a disconnected sensor, a broken signal wire, or a failed sensor element.
