Code P0114: Intake Air Temperature Sensor 1 Circuit Intermittent Bank 1
Diagnostic & Technical Explanation
Code P0114 (Intake Air Temperature Sensor 1 Circuit Intermittent Bank 1) sets when the ECM sees an open, shorted, or implausible resistance from an intake air temperature sensor (any position/bank), or a correlation mismatch against a related ambient or fuel temperature signal. Causes are a corroded connector, a failed thermistor element, or chafed harness wiring near the intake tract.
