ok so i have not yet been able to figure my vtec out, my cars basically rev limiter is at 6400 instead of 7200 or what ever it is supposed to be and i have no vtec. all the wiring is there, the ecu is good and everything else to not sure if it would be the vtec solenoid?

Check engine light on?

speed_demon018

no it is not

speed_demon018

anybody else with suggestions on what the problem could be

Check the solenoid. If thats good then go back over the wiring and make sure its correct. There is wiring diagrams floating all over this site with the digram so it shouldnt be to hard to find.

how do you check the solenoid

Former User

Does the CEL work [turns on for 2 seconds when key turned to ON(II)]?

What ECU do you have?

Is the filter in the solenoid clogged?

Is the oil pressure low?

civicsmoke

make sure you have a p28. and check your ground for vtec

speed_demon018

i have a p28 CEL works filter looks good oil pressure is good and where is the ground for vtec

How do you know the ECU is good?

speed_demon018

i used a friends good ecu and it does the same thign

Former User

Will your buddy also let you swap in his VTEC solenoid and pressure switch?

speed_demon018

all he had was the ecu he does not have a single cam car i wish he did

speed_demon018

is there gaskets for these

HitF8

I would try to get your hands on another solenoid and see if it does the same thing

speed_demon018

yeah but is there any gaskets for the solenoid

Former User

Yes

speed_demon018

do you have to replace the gasket after you pull it off

speed_demon018

and would these things cause the 6200 rpm redline?

Former User

If the solenoid is not leaking oil, then the gasket should be fine. Just make sure the filter is not clogged. Also do the tests in the diagram.

speed_demon018

the only thing i couldnt test is the solenoid its self my multi meter fried so i do not have one but everything else looks good

Former User

Borrow a multimeter. Or buy a new digital multimeter ($15-$20). You'll need this anyway to test the wiring.

speed_demon018

sad thing is i dont know anybody with one lol

speed_demon018

but ronj could the solenoid if bad cause a 6200 redline

A basic digital multimeter is not very expensive. Call around to Walmart, Sears, Harbor Freight, etc. for the best price. You must have this basic tool to work on your car. Good investment.
