There are 2 ways you can attack the ICP sensor. I prefer to remove them from underneath if only the sensor needs replacing, but in most cases the sensor will have leaked and damaged the wiring. In that case, drain out a few liters of coolant and remove the degas bottle and FICM. With those removed, the sensor can be reached with a 1 1/16" crows foot, an extension and ratchet. Wear gloves that will keep you from bashing your knuckles when it breaks free because they are REALLY tight. It is in a really tight spot, but be patient and you can get it. To reinstall the sensor, I put a piece of hose over it to try to manuever it into place because there is really not that much room for getting you hands in there. And don't forget, if the sensor has leaked oil into the wiring, the pigtail will need to be replaced.
