PRESSURE REGULATOR CONTROL SYSTEM
F2-119component photoInputs include both MTX (neutral switch, clutch switch) and ATX (transaxle range switch) variants.
DESCRIPTION
To prevent percolation of the fuel during hot restart idle, vacuum to the pressure regulator is momentarily cut and the fuel injection pressure is increased to slightly more than 284 kPa {2.9 kgf/cm2, 41.2 psi}. Pressure in the fuel line at idle is approx. 226 kPa {2.3 kgf/cm2, 32.7 psi}.
