P0114 — Intake Air Temperature Sensor Intermittent
The IAT signal shows intermittent dropouts or jumps that fall outside slope expectations but do not stay above or below threshold long enough to trigger P0112/P0113. Usually a wiring or connector issue.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
