Looks like Vtec wont hit in sometimes...

- Mon Sep 13, 2010 4:10 pm #213420 Allright, i got the feeling my Vtec wont hit in sometimes..
I did a couple of runs gear 1,2,3.. and then brake all to 8900/9000 RPM.
After i noticed/thought my vtec didn't hit in, i removed the plug of the Vtec solonoid (now i dont get vtec, right??) After i did that, i gave speed again and waited to vtec hit in, nothing happend. But it was the same feeling as the 2 runs before... So.. whats broke or soo..?
Also i did not get a Engine code... :?

If the engine is in good shape, maybe it's just an electrical gremlin.

Or the screen on the vtec solenoid gasket could be clogged :thumb:

Vtec only works with you have the correct load and oil pressure.
