So Why Do Cars Turn Off Because Of Air Intake Temp Sensors

Defective air intake temp sensors can element idling problems in blasting weather.

Boiling air is not as arduous as algid air and in consequence requires less fuel to balance an engine's air/fuel ratio. The intake air temperature sensor keeps track of the temperature of the air going into an engine. This important facts is then used by an engine's machine (PCM), which allows it to deposit air/fuel brew in balance.


An intake air temperature sensor is usually positioned in the intake manifold so that its gratuity can expedient the air going into the engine. The PCM sends all over 5 volts to the sensor and waits for a voltage word response.There are several reasons why an air intake temperature sensor can fail, such as bad electrical connections, which lead to incorrect sensor output. Oil from the intake manifold can also coat and contaminate the sensor, limiting its ability to properly monitor air temperature.

This in turn leads to idling problems, which can cause a car to shut off, especially in cold weather. Other driving problems include trouble accelerating as well as engine surging.


Air intake sensors hog firm resistence reactions to contradistinct air temperatures, and this resistence Testament conclude the voltage reading that's sent back to the PCM.


Defective air intake temperature sensors can accommodate incorrect readings to a vehicle's PCM. This can cause the PCM to mistake warm air for cold air, which will result in incorrect air/fuel mixture.
