have a JDM 2nd gen. b16a with obd1 p30.
what would cause not to hear vtec?
everything runs strong but cant hear vtec?
NO CEL. OIL IS GOOD.
REASONS:

 

either somethings wrong and it isn't engaging, which you would notice, or your idea of vtec engaging is different than you think...

 

no CEL?

 

lack of oil, or cel's...

 

BUMP !!!!!

 

clean the silenoid filter too

 

do you FEEL vtec? that's the important part

and like everyone else said; no cel's?

 

i use to have a b16a2 in the car. vtec i can hear it roar. but this one i cant hear it scream or roar at all. idk i gotta check it. no CEL either

 

i'm not sure if the oil line to the vtec is connected i gotta double check tommorow.

 

i was sitting on the passenger. passenger do feel all the power instead of driver.
hrmm...i don't remember ahahah.

 

Is the silenoid wiring done right? Is it grounded?

 

Vtec fluid. You need it.

 

Grounded? i dont remember Vtec Solenoid needing to be grounded. but i didnt do the swap so i wouldn't know but i'll check on tat too.

 

Does the tach work?

 

the wires for your vtec pressure switch.. one goes back the the shock tower the other is a ground to the solenoid. if there isn't any CEL's then you need to clean the vtec solenoid out and make sure you have your oil topped off.

 

yeah i see the RPM flying but hear no vtec.

 

he meant the mph not the rpms. if the vss is bad your mph tach wont work not letting vtec engage.

 

Yeah, theres three wires on the silenoid, 2 to the ecu and 1 is grounded... Yea, Ur MPH tach also has something to do with vtec cracking...

 

You dont always hear vtec. It depends on the exhaust, the intake, and where the x-over is in relation to stock. Most times it's almost unnoticeable though.
