I have an 01 4cyl and wanted to know if the screws on the map sensor are phillips head or require some special bit? If so which is it?

 

Use a good phillips screwdriver and put it on the screw, then tap it pretty hard with a hammer. Then push down while turning counter clockwise.

 

I believe they're screws; unlike, the TPS where they're riveted to the TB cause Honda doesn't want us to be messing with it.

 

I've always found the easiest way to remove those screws is to use an electric drill/driver and set the torque setting really low, then moving it up as needed. After a few seconds they usually back right out without damaging the heads. Just like using an impact on those stubborn nuts/bolts.

 

I took it out twice, second time the head just became a nice little circle... the crappiest head i ve ever seen... becarefull take in it out
