P0114 - Intake Air Temperature Circuit Intermittent
Intake air temperature signal cuts in and out or drops out.
Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.
Code Overview
Intake air temperature signal cuts in and out or drops out.
Common Causes
- Loose IAT connector
- Broken/chafed wiring
- Failing IAT sensor
Diagnostic Steps
- Wiggle-test the connector while watching scan data
- Inspect harness near the intake tube
- Compare IAT reading to ambient when cold
Likely Repairs & Cost Guides
Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.
Next Steps
Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
