Honda Accord VTEC actuator question...

[hcmpls1]

Could anyone tell me specifically what a VTEC actuator is? I’m trying to troubleshoot an issue I’m having with a 2008 V6 Honda Accord and a lot of people with similar issues are calling out this part on other forums… No one says exactly what this part does and I am curious. Also, is it part of the drive train and thus covered under that part of the warranty? I'm going to give the dealer a call tomorrow but thought I'd throw it out there to see if any of you guys know. Thanks

I believe it is the actuator involved in adjusting/changing the cam timing.

It is part of the engine and/or drivetrain so I would think it would be covered.

The vtec solenoid allows oil pressure to activate a pin that will lock in an extra set of rockers that will open an extra set of valves when you punch it.

The solenoid assembly usually consists of a solenoid an a pair of pressure sensors. It is typically located on the backside of the head on the passenger side.

I've not had the opportunity to work on one of these before so I did a little reading last night.

Its a pretty ingenius setup with different variations for performance or economy based on application.

There is a good amount of discussion about them involving noise at cold startup, malfunction due to sludge, and a whole bunch of high performance mods for them.

Pretty interesting stuff.....

Yeah, I've been experiencing a grinding noise at start up the past week... I stumbled onto a number of people with the same problem for model/year and cited thr VTEC actuator as being the problem. I have 57K miles and the powertrain warranty is 60K. Would this part fall under powrtrain?
