Are you after the Poly Vinyl Chloride valve, or the Positive Crankcase Ventilation valve? :>)

Hope this helps

if they didn't read the fault codes before starting work, they are repairing by replacement and that is not good
if a sensor is faulty and it could be a cam shaft sensor as well as a crankshaft sensor , normally it misfires or stops altogether
the ECM is in limp mode and that reduced the engine power and if there was a sensor problem it would not just reduce power and put the light on but would show up in a define manner
engine lights also come on it there is a transmission problem and that will also initiate the limp mode
have the fault codes read to determine the faulty part/ sensor

Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

Have you checked for trouble codes ?
Is the fuel pressure normal ?

reduced power mode is usually activated to protect the engine , have you check all the fluid levels as a starting point, as have no code to guide you

My 2005 came up with this also, it continually became more frequent. Had to replace the throttle body.

what oil are you using?
