Product Questions & Answers

Q:What is the purpose of this sensor?
Jennifer H.
A:BEST ANSWERHi Jennifer, thanks for initiating contact. The AT Sensor, also known as an Intake Air Temperature (IAT) sensor, serves a critical function in automotive engines. Its primary purpose is to measure the temperature of the air entering the engine. This information is essential for the engine control unit (ECU) to optimize the air-fuel mixture for combustion.

P2199 Code: Intake Air Temperature Sensor 1/2 CorrelationThe diagnostic trouble code (DTC) P2199 indicates “Intake Air Temperature Sensor 1/2 Correlation.” The PCM will log a P2199 code if it detects a large discrepancy between the voltage signals sent by different IAT sensors.
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.
P0097 Code: Intake Air Temperature Sensor (IAT) Sensor 2 Circuit Low (Bank 1)
P0097 Code: Intake Air Temperature Sensor (IAT) Sensor 2 Circuit Low (Bank 1)Diagnostic Trouble Code (DTC) P0097 stands for “IAT Sensor 2 Circuit Low (Bank 1).” It is triggered when your vehicle’s powertrain control module (PCM) perceives an irregularity in the intake air temperature #2 readings.
