Hey TR,

i got a b16a in my eg hatch that throws a vtec pressure switch code when im in high RPM's

its only doing it when i hit about 6800 - 7000 rpms in 4th, so im going about 80 mph.
if i stop nd shut the car off and start it again it goes away and doesn't come back until i get
back into high rpms. I don't lose power (except that im out of vtec when i need it).

Any ideas? besides checking wires and connections i havn't tried anything. Let me know TR!
