Sometimes you get the “OC” on your head up display. That means a failed or missing Temp Sensor. If you are upgrading to a 5 button DIC then you will need to add this sensor.

How did you clean your sensor?
I've changed this sensor because it would say my temperature is only in the 30s or 40s. Sometimes it will say 88 when I start the car up then drop back down to the 30s or 40s within a minute. Is there a different sensor that will correct this?
does this sensor have any effect on the driver side fan?
how did you clean it
Does that stop the a/c from coming on
I been trying to find this for so long. thanks
