This is a quick video on how to replace or clean the Idle Air Control sensor on a 2002 Dodge Ram 1500 with 4.7 liter V8. Before Starting, disconnect the negative battery cable. 1) You first have to remove the big air box and air intake pipe which comes off in about 2 minutes. The square box is only held down by two bolts ( one on the right and one on the left) and a hose on the rear side ( just pull it and it'll slide off). Also, you have to loosen the screw that clamps the intake hose onto the throttle body. Then slide the full box and hose off... You will then see the black IAC sensor held in place with star headed screws. I used an allen wrench and it worked out ok. There are 2 screws. Un-plug the connector for more room to reach the screw in the back... Then clean or replace the IAC with a new one.
Just an FYI, I think the IAC sensor is different on '02s and '03+ models... I dont know why, I thought they were basically the same truck. Rock auto has the part for $56.99 or you can get it at Autozone.
