Hello, any link belt gurus out there ? We have a 4jj1 that keeps throwing codes !p1093 and p0234 I have checked the vaccum tube going to wastegate diaphragm and it appears to be fine Replaced both fuel filters. The codes do not happen until the machine has been operating for several hours, and is warmed up Thanks for any advise this has been quite a pest
Is there supposed to be boost at idle? Are we supposed to subtract atmospheric pressure from the pressure sensor value?
That have to be absolute pressures. The barometric pressure surely are absolute so the boost press must be absolute too or it would be very confusing othervise. So the relative boost pressure you have must be 1.9 psi
