P2199 Code: Intake Air Temperature Sensor 1/2 Correlation
P2199 Code: Intake Air Temperature Sensor 1/2 CorrelationVehicles have more than one intake air temperature sensor, and their location may vary depending on the vehicle’s manufacturer. Most IAT sensors can be found in the air intake pipe or air filter housing. A different design is built into the housing of the mass air flow sensor.
P0110 Code: Intake Air Temperature Sensor 1 Circuit (Bank 1)
P0110 Code: Intake Air Temperature Sensor 1 Circuit (Bank 1)The IAT sensor is a negative temperature coefficient (NTC) thermistor that decreases in resistance as the temperature of the sensor increases. Its purpose is to measure the temperature of the air entering the engine and provide this data to the PCM.
8 of the Most Important Car Sensors You Should Know About
8 of the Most Important Car Sensors You Should Know AboutAs a driver, you must know what these sensors are and how they contribute to your vehicle’s performance. Here are some of the most common car sensors you should know about. Oxygen Sensor The oxygen (O2) sensor measures the exhaust’s oxygen content.
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 IAT sensor is a thermistor. Its resistance decreases as its temperature increases. As the temperature rises, the sensor becomes more electrically conductive. It is usually a two-wire sensor that has one wire supplying voltage to the PCM, while the other is a ground.
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)To be specific, this code may be logged once the PCM detects that the air temperature reading in sensor #2 is unusually high (causing low voltage resistance) when the engine temperature is low. Bank 1 refers to the side of the engine that contains the #1 cylinder. Code P0097 may
P0098 Code: IAT Sensor 2 Circuit High (Bank 1)
P0098 Code: IAT Sensor 2 Circuit High (Bank 1)Read our technical discussion about the IAT sensor and how it can trigger codes like P0098 to get more information that can help you fix the issue.
