You're talking about the sensor for the dashboard gauge or the one for the ECU? The one for the dashboard gauge is easy. as soon as you take off the plastic engine cover, you will see it sticking out vertically near the coolant pipe 90 degree bend that feeds into the engine block.

I'm trying to change my idler pulley that goes to my alternator belt but it keeps rubbing against the metal part between the pulley and the tensioner, so I tried adding washers but that didn't help because the tensioner keeps tilting forward and that is what's cause the pulley to rub. Is there anyway to fix this issue?
