i was getting a cel for my intake air temp., so i went looking for it only to find there isn't one plugged in. there is absolutely no place to plug it into the intake i have, which doesn't look to be after market, but i don't know for sure. is there any honda manifold that doesn't have a iat sensor? by the way i pluged an extra sensor into the wire for the iat and the code went off. so i guess my real question is what all does that sensor do and can i go without one. i could just plug in the sensor to the wire to get rid of the cel, but i have no idea what problems that might cause. someone said on another thread that if you are throwing any cel's then your car will go into limp mode, it this is true i have other cel questions because mine is throwing the automatic lock up selinoid(or however you spell that word) code also, and my car has been converted to manual. so i my p28 for an automatic? any way i'm lost please help.
