92 prelude with a edm f20b dohc vtec. I'm getting a code 22 which is the vtec pressure sensor. I tried the trick of bypassing the sensor but I just gave me a vtec solenoid code 21. Is this engine supposed to have a single wire vtec solenoid? Also this is on a usdm p13 ecu.

Look at the solenoid, most likely you have junk in the gasket/filter. 

As for the rest not completely sure.

Cool ill check that out tomorrow and report back. This is my first problem with vtec engaging and also my first gaylude, so all I can go by is the retarded prelude forums which all the thread end up people just asking about how much swaps cost

[Joseph Davis]

If you can define exactly when the code pops I can help.  But, agreed, check solenoid screen first.

How much did your swap cost?

I bought it from a guy in the fluffy crew for 41 cheese burgers. On a side not vtec seems to be engaging even with the code 22
