What is this hole (maybe some kind of sensor?)

Asked by Oct 12, 2016 at 05:11 PM about the 2011 Ford Focus

Question type: General

What is this?

This is some kind of sensor, I think. But it makes a noise sometimes. So I put tape over it. Or sometimes, I put my finger into it to stop a motor in the sensor, so the noise stop temporally.

A noise really irritates me.

opps, maybe it is difficult to see by above photo. bellow is better one https://s11.postimg.org/tj42rlj9f/DSC_0kk033.jpg Do you see a hole between my shoe and key cylinder?


Looks like an in car temperature sensor for an automatic climate control system (just a guess based on what I've seen on other vehicles). HTH. -Jim

temp sensor? hun.. It has small motor inside which rotate all the time. it must be sucking air or putting out something


It is the in car temp sensor.. it will make noise when it's clogged try blowing it out with compressed air

thanks all!!


That is a dual purpose sensor. It can monitor the temperature in the car for cooling purposes and also allows the nsa to listen in on your conversations. The tape was a good idea
