Differential Pressure Regulator Electrical System
- Connect Pressure Gauge (VW 1318
) as previously described. See Figure
. Close pressure gauge valve. Disconnect differential pressure regulator connector from side of regulator.
- Using Adapter (1315 A/1
), connect Multimeter (US 1119
) to differential pressure regulator and to the connector removed from the regulator. See Fig 1
.
- Set multimeter to 200Ma DC scale. Turn ignition on. Multimeter should read 100Ma. Pressure gauge should read 17-22 psi (1.2-1.5 kg/cm2
) less than readings noted in the FUEL INJECTION SYSTEM PRESSURE test.
