Fuel Injector: Description and Operation

When the Automatic Shut Down (ASD) relay contacts close, they connect circuits A14 and A142. Circuit A142 supplies voltage to the fuel injectors. Each injector has a separate ground circuit controlled by the Powertrain Control Module (PCM).

- Circuit K11 provides ground for injector number one. The K11 circuit connects to cavity 16 of the PCM.

- Circuit K12 provides ground for injector number two. The K12 circuit connects to cavity 15 of the PCM.

- Circuit K1 3 provides ground for injector number three. The K13 circuit connects to cavity 14 of the PCM

- Circuit K14 provides ground for injector number four. The K14 circuit connects to cavity 13 of the PCM.

- Circuit K15 provides ground for injector number five. The K15 circuit connects to cavity 38 of the PCM.

- Circuit K16 provides ground for injector number six. The K16 circuit connects to cavity 58 of the PCM.

- Circuit K17 provides ground for injector number seven. The K17 circuit connects to cavity 17 of the PCM.

- Circuit K18 provides ground for injector number eight. The K18 circuit connects to cavity 18 of the PCM.
