P0114 Code: Intake Air Temperature Sensor 1 Intermittent / Erratic (Bank 1)
P0114 Code: Intake Air Temperature Sensor 1 Intermittent / Erratic (Bank 1)The intake air temperature sensor measures the air temperature entering the intake manifold. The PCM uses the input signal from the intake air temperature sensor to calculate the ignition timing strategy, fuel delivery, and many components of the emissions control system.  As such, the P0114 code should be addressed immediately
P0111 Code: Intake Air Temperature Sensor 1 Circuit Range / Performance (Bank 1)
P0111 Code: Intake Air Temperature Sensor 1 Circuit Range / Performance (Bank 1)The sensor 1 portion of the code applies to vehicles that have multiple IAT sensors. Bank 1 points to the side of the engine opposite the #1 cylinder.
P0127 Code: Intake Air Temperature Too High
P0127 Code: Intake Air Temperature Too HighDiagnostic trouble code (DTC) P0127 stands for “Intake Air Temperature Too High.” This code indicates higher than expected air temperature based on the sensor input, which can be skewed due to a bad thermistor or a partially shorted circuit.
