I'm working on a CAI so I pulled the plug on the intake air temperature sensor, I think... it's the one on the air canister. After the car warmed up, the check engine soon light popped on so I pulled over and plugged it back in and it ran fine... What do I do with this sensor when I setup the CAI? Does this sensor need to be grounded or anything? Should I just thread a whole in the new pipe I’m using and stick it in? Can I leave it outside the pipe and just attach it to the frame or something?

Thanks,
Steve
