Title: Mystery sensor advice please
Post by: Arnie_O on November 15, 2012, 11:35:23 PM
Hi guys.
Come across this plug today while working on an FD... not seen it before. Have compared it to another car but the sensor is not connected to the plug on the other car.

I cant seem to find where it goes.

advice as to what it is and where it lives would be good.

And would it effect starting?

Is it safe to unplug this sensor even if I am on standard ECU?
