The air cleaner temperature sensor is not very common on newer vehicles. This is because in order to ensure that a car engine operates the way it should, several electronic sensors may actually be required. However, if you drive an older model vehicle, your vehicle almost certainly has an air cleaner temperature sensor. It is found inside the breather housing, and works mainly as a vacuum sensor, although it does also contain some electronic parts.
The air cleaner temperature sensor has only one duty – it gives information to your car’s computer so that it can ensure that the air/fuel mix is accurate, regardless of the speed at which you are riding. This means that as soon as you start up your car, the air cleaner temperature sensor starts to work.
The air cleaner temperature sensor is not a component that is replaced after a certain number of miles, or after so many years. It has no specific lifespan, and could last the lifespan of your vehicle. However, as is the case with all parts that contain electronic components, the air cleaner temperature sensor can be vulnerable to corrosion, and it can also be damaged easily because of its location inside the breather unit and just changing an air filter places the sensor at risk of impact.
Signs that your air cleaner temperature sensor needs replacement include:
- Check Engine Light coming on
- Car idles rough or stalls when cold
You can still drive the vehicle if your air cleaner temperature sensor is failing, but performance will suffer. If you think that it feel it needs replacement, consult a qualified Auto mechanic. A mechanic can find out why your vehicle is idling rough or stalling, and if need br replace it.
