OK, I´d like to install my newly-purchased K&N filter on my 1.9L engine, but there´s still one little thing standing in my way. It´s that darn IAT Sensor (intake air temp) which plugs into the cover of my airbox. The filter I plan to install requires removal of the airbox, so just what DO I do with this sensor?
According to my Chilton manual, that thing ´senses the intake air temperature and sends that information to the Powertrain Control Module (PCM)´, which ´calculates the correct amount of fuel injection.´ Doesn´t seem like I could just unplug and forget about it, without it affecting how my engine runs.
Hey, if you´ve removed the airbox on your 1.9L engine to upgrade the intake, I´d like to know what you did with that IAT sensor. Thanx!
