DTC P0201-P0208, P0261-P0262, P0264-P0265, P0267-P0268, P0270-P0271, P0273-P0274, P0276-P0277, P0279-P0280, & P0282-P0283: Fuel Injector Circuit Malfunction: Description

Multiport Sequential Fuel Injection (SFI) system uses one fuel injector per cylinder. Fuel injectors are fitted between pressurized fuel rail and intake manifold. Each injector contains a solenoid controlled by ECM. When solenoid is energized, a plunger is pulled off its seat and allows pressurized fuel to spray into the intake manifold. Fuel injector total failure or a leak that causes a rich mixture will cause a misfire in affected cylinder.

On Discovery, the fuel injectors are supplied with battery voltage through the main relay via fuse No. 1 (30-amp) located in engine compartment fuse box. On Range Rover, the fuel injectors are supplied with battery voltage through the main relay via fuse No. 37 (30-amp) located in engine compartment fuse box. On all models, fuel injector operation is controlled by the ECM through the ground path of each fuel injector. This facility allows the ECM to control the fuel injectors so that sequential fuel injection can take place.

Specific fuel injector failures will generate a specific DTC for suspect injector that are stored in the ECM as follows:
