Re: Help-2007 Tundra has poor power, blinking engine & 4 LO light, VSC on, Accellera

I tried the "tap on the valve" method suggested in another thread here discussing the same AIP system failure. You need a long screwdriver for the Driver's side valve. I had to use something much longer for the passenger side valve, and I accessed it from below the passenger side inside the frame rail beside the transmission. As suggested before YMMV and please use discretion with your tapping, as the valve bodies are made of aluminum and plastic....

Once the tapping was complete I reconnected the air pump electrical connectors and re connected the battery. Upon startup my CEL was cleared and the return of the blinking lights and CEL has not happened! Two days of driving and all is well!
