I have searched and cant find a defined answer so i am asking will the vtec solenoid stop my car from reving past 5k rpm

car info
94 ej1
1st gen b16a from crx
obd1 p72 ecu
usdm vtec solenoid with oil pressure switch
any other info needed dont hesitate to ask

 

Is this a recent swap? has it worked before?

 

I'm going to say doubtful since I have yet to have a problem with any aspects of VTEC. Any CELs?

 

the swap was done over a year ago and at one point it did run fine but i purchased the car with intent to pull the engine to put it in my ej1 and i just wanted to make sure everything was running correctly before i pulled it and there is no cel coming up so i am stumped about to try another vtec solenoid to see if thats it but im clueless right now

 

So if there is no CEL how do you suppose it's the solenoid? Just trying to follow the thinking in case I ever have the issue..

 

My car came with the CEL pulled out, so it didnt appear to be on... CEL should pop up when the keys are in accy position... If the light was removed for some reason, and there really is a light, it should point you in the right direction.

 

the light does work but i have read that if you have a jdm solenoid with a usdm ecu then you will have a cel but i checked all of that earlier and i have the usdm solenoid with the oil pressure switch and a usdm obd1 p72 from a 94-95 gsr so im stumped why it wont go over 5k rpm

 

i cant think of anything else it could be that would stop it from reving over 5k rpm

 

well changed the vtec solenoid and it ran great for a few min but then threw code 23 (knock sensor) so now trying to fix that thanks for the imput
