Fuel Pressure Sensor/Switch: Service and Repair

Fuel Pressure Sensor

If the Fuel Pressure Sensor (G247) should fail, the Fuel Pressure Regulator Valve (N276) will switch off, the electric fuel pump is completely
controlled and the engine will be driven by the fuel pressure present. This will reduce the engine torque dramatically. 

Special tools, testers and auxiliary items required

‹› Assembly tool (T10118)

‹› Socket wrench insert 27 mm (VAS 5301/7)

Removing

-

Remove engine cover carefully.

CAUTION!
Fuel system is under pressure! Fuel pressure must be reduced to a residual pressure before opening high pressure area of injection
system. Refer to => [ Before Opening High Pressure Fuel Injection System ] See: Fuel Filter/Fuel Pressure Release/Service and Repair. 

-

Remove coolant line bolt - arrow - from intake manifold. 

-

Disengage connector from fuel pressure sensor using assembly tool (T10118).

-

Remove fuel pressure sensor using socket wrench insert 27 mm (VAS 5301/7).
