ive had my b16 in my 88 si crx for about 2 weeks. A couple days ago, i was revving it and it wouldnt go past 7300. I checked the ecu code and it said 22, which is the oil pressure i believe. i drained and changed the oil, but its still doing it. The akward thing is, after the car warms up, and i restart the engine, it revs fine. Any suggestions?

 

Maybe the oil pressure sensor is bad?? Just a thought. I have yet to run into this problem on my swap.

 

22 is the vtec oil pressure switch. Any clue why it would go off after the engine warms up?

 

try replacing the swtich with another one......and reset the ecu

 

if you can swap it out try that first also check the spool valve (vtec soleniod) filter/gasket sometimes you get crap stuck in there and it won't get any prss
