Vsv Fuel Pressure Control at Isabel Hudson blog

Vsv Fuel Pressure Control. When activated this vsv prevents manifold vacuum from reaching the fpr (fuel pressure regulator). It's job is to let the fuel regulator sense atmospheric pressure instead of manifold vacuum when performing a hot start. The fuel pressure up system (fpu) is designed to reduce the possibility of vapor formation in the fuel rail after hot soak and is used on many tccs engines. The ecu sends signals to the fuel pressure regulator vsv to increase fuel pressure based on intake air temperature, coolant temperature and starting signal. It utilizes an ecu controlled. I noticed that the fuel pressure did not drop at all when i pulled the vac line off the fpr and measured the line to have no vacuum (due to the. Connect the vsv terminals to the battery terminals as illustrated. When vacuum is removed from the fpr the fuel pressure jumps from ~30psi to ~40psi.
