My dealer told me that it needed to be replaced, and quoted me 280, he told me affects the performance of the engine, dont really know what it does, since he was very vague except the price, any help here guys would be appreciated. Also for some reason when im driving I have a lot of hesitation when i take my foot off the pedal, like the car wants to stall, wondering if this thing is related to the VCV
tino

 

is it vcv valve or pcv valve? i dont know much about cars but the only one i know about is the pcv valve, and if thats wut u mean, dont u dare let them do that for 280 fcukin dollars, its a 5 dollar part and takes maybe 15 minutes to change urself!!!thats 275 dollars /hour their gonna get u for.....if u meant pcv valve and not vcv

 

"Vacuum Valve (vacuum Control Valve)
A power brake unit is made to take advantage of the vacuum the car's engine produces. A vacuum control valve allows vacuum from the engine into one side of the piston, and keeps normal atmospheric pressure on the other side. It is placed between the brake and the master cylinder piston. "
He was probably, most likely referring to the vcv and not the pcv.

 

gotcha, see....told ya i dont know bout cars....darn, i think i have a code for that now that i think of it, stupid me

 

its actually a vent control valve, thats what was written down to me, i dont if its a whole lot different than the vacuum control valve

 

All of this is completely WRONG!! The VCV is part of the evap system. Basically, it relieves the fuel tank of built up vapors via vacuum and burns them in the engine. It does NOT effect performance at all!! It is strickly emissions bullsh!t so when you open your gas cap all the vapors dont go spewing out into the atmosphere. All of this is from the FSM so dont even bother arguing with it.

I dont know exactly how much a new valve costs, but it is probably cheap if you get it from one of the nissan wholesalers. Actual replacement takes probably less than 30 minutes and a novice could do it.

Currently I am tripping the 0801 code which is the VCVBV. I have been driving around with it for several months now with out any adverse effects. Once a day I open my gas cap to relieve the tank of all the built up vapors.

 

^^ dude's smart!

 

im havin same stalling, hesitation prob with my 95, i did notice alot of pressure in the tank. ive done plugs, fuel filter, pcv, air filter, seafoam, tb, checked for vac leaks. this car is dangerous, starts cuttin out , black smoke, gotta put it to the floor to clear it out !!! sometimes it seems fine, then outta nowhere.....

 

Smart because he reads.
