allright I have been running my b16a for some time without any problems with vtec kicking over. But I recently had some problems with the fuse that goes to the ignition, but it was just a bad fuse so my car would not start. but I changed the fuse and now I am pulling ecu code 22, and my vtec will not kick over. any suggestions would be greatly appreciated. I would like to get this fixed fast
thanks

 

change your oil, check your wiring, see if you have good continuity from the oil pressure plug to the ecu.

check for resistance on the oil sensor plug see if its any good

do a search on all that, should be good

are you running a v-afc? there is a wire called a VTM wire, that needs to be hooked up

 

what does this vtm wire do???

 

It's an oil pressure switch, to make sure you have oil pressure or else you can't go into VTEC. I think only the USDM engines/ECUs use this switch. If you have a JDM engine, and a USDM ECU, you will have to ground that pin on the ECU, preferably with a 10 ohm resistor. That's what I did on my ZC anyway.

 

it's a jdm engine with a usdm p28, I am sure that all the wiring is good however, I took the pan off to tap for turbo and I think that something is clogging the oil pick up so that I don't have pressure. is there any way to test for oil pressure without haveing to buy a oil pressure gauge.
