– Connect the Digital Manometer - VAS6394/1- to the Pressure
Sensor Tester Adapter - VAS6394/2- .
– Start the engine.
– Compare the pressure shown in the Digital Manometer -
VAS6394/1- with the actual value in the Vehicle Diagnostic
Tester
• The pressures may have a maximum difference of 5 bar (72.5
psi).
– If the difference is greater than 5 bar (72.5 psi), test a new Fuel
Pressure Sensor - G247- .
CAUTION
Fuel system is under high pressure.
Risk of injury from fuel spraying out.
– Reducing the fuel high pressure.
– Insert the new Fuel Pressure Sensor - G247- in the Digital
Manometer - VAS6394/1- .
– Repeat the test with the new Fuel Pressure Sensor - G247-
and compare both values.
If the Measured Values Do Not Now Match Again
– Check the electrical connectors between the Fuel Pressure
Sensor - G247- and the ECM. Refer to ⇒ Wiring diagrams,
Troubleshooting & Component locations.
If the Measured Values Now Match
– Install a new Fuel Pressure Sensor - G247- . Refer to
⇒ 5.2 Fuel Pressure Sensor G247 , Removing and Installing,
page 314 .
Tightening Specifications
♦ Refer to
⇒ 4.2.1 Overview - Intake Manifold Lower Section with Fuel
Rail, Direct Fuel Injection, page 300 .
5.4 Low Fuel Pressure Sensor - G410- , Re‐
moving and Installing
Caution
This procedure contains mandatory replaceable parts. Refer
to component overview prior to starting procedure.
Mandatory Replacement Parts
♦ O-ring - Low fuel Pressure Sensor
Note
Only on vehicles with intake-manifold fuel injection
Removing
– Remove the engine cover. Refer to
