i am having this problem with my s2000, the car is warmed up, has 3 bars its warmed up but when i punch it feels like it tops out around 6k rpm and vtec would not kick in, can any one help me or has had the same issue.

 

any lights on the dash?

 

Feels like it tops out around 6k RPM?

 

Probably a bad VTEC solenoid. Thats the valve that sends engine oil into the valvetrain to engage VTEC

 

Check your oil level. Are you low? If so VTEC won't kick in. Yo.

 

Does it stop revving completely at 6k?

 

check engine but it says p0410

 

yeah

 

oil is fine, car was warmed out, will be a sensor probably..

 

I changed the VTEC Solenoid and VTEC kicks in,, thanks,,
