Electronic Engine Controls

Fuel Injectors





The engine has 8 fuel injectors (one per cylinder), each injector is directly driven by the ECM (engine control module). The injectors are fed by a common fuel rail as part of a 'returnless' fuel system. The fuel rail pressure is regulated to 4.5 bar by a fuel pressure regulator which is integral to the fuel pump module, within the fuel tank. The injectors can be checked by resistance checks. There is a fuel pressure test Schrader valve attached to the fuel rail on the front LH (left-hand) side for fuel pressure testing purposes. The ECM (engine control module) monitors the output power stages of the injector drivers for electrical faults.

The injectors have a resistance of 13.8 Ohms ± 0.7 Ohms @ 20 Degrees Celsius.
