Thank you for this quick reply.
Is it really for AIR temp?
because the value is very similar to the one at 20C for the coolant temperature.
Is it a PTC or a NTC?

G'afternoon all,

I have the sensor as well and wondering what does it affect?

Also how can we clean it ? As it seems to be black with soot...

Thanks in advance. My harness for this sensor is broken and I have proceed to use splicing tape to cover it back.

Enjoy!
