Why vtec not working

It always sucks to have these kinds of issues, so let me get that out the way first. Can I ask a few more questions? Did your VTEC ever work? Original ECU? What does oil pressure look like? If your VTEC solenoid is clicking over, do you see the camshaft rocker pin move at all? Hey I have a jdm b16a ob2a with stock ecu in an ek.

It seems like vtec is engaging at but right after it engages it seems to disengage? There is no cel and the oil is topped up. Hi Justin, have you checked your LSA?

Have you cleaned your VTEC solenoid? Problems with either issue can cause VTEC to not work. Check out these guides to help you out. Sorry, are you asking about a project or you are wondering how to connect the VTEC solenoid to your Prelude?

Hi Mauricio, thanks for reading! Hi Luke, thanks for reading. If you are using a stock ecu then there are several things that have to occur for it to engage.

If you are chipped you can turn off the VSS, oil pressure and set the engage rpm. Oh well thats good you got it fixed. I was going to ask you, how in the hell did you put a test checker light on the solenoid.

It is possible that vtec is not mechanically engaging If it does, you know its good. Then i would test to make sure when the ecu changes over to the vtec map, you get the signal to the solenoid.

You'll have to be creative on this because we usually do it on the dyno. If that checks out fine, then you'll want to make sure that the pins are actually locking in the head. Thanks all for the help! Registered VIP.

Vtec works a specific way. RPMs, oil temp, oil preasure, vehicle speed, and throttle positioning are what the ECU uses to determine the use of Vtec.
