Nvcs

[Reedo]

Hey everyone.

Need some help with my NVCS (nissan variable cam system?)

So my mechanic took my 33 for a spin today (its running an r34 25de), he said due to my check engine light being on the 'vtec' isnt kicking in. is this right or is the sensor broken?

check engine light is on due to the secondary speedo sensor wiring being lose.

I know with my ecu (r34 in stagea) in the nistune there is a setting for minimum speed to enable vct. Oñ the neo pretty sure it was set to 0, but the 33 could be different, so chances are lack of speed input is causing the issue.

AKAIK it just goes of the neutral switch. As long as the car isn't in neutral the VCT will work

Alot of 33's have the Neutral switch bridged out so the car thinks it is constantly in gear. My VCT clicks on and off when the car sits still if you give it a quick stab of throttle
