Fuel Injectors Description
FUEL INJECTORSCircuit A14 is a bus bar in the Power Distribution Center (PDC), and connects to battery voltage. The contact side of the Automatic Shut-Down (ASD) relay connects circuit A14 and circuit A142. A 20 amp fuse in the PDC protects circuits A14 and A142.
Circuit A14 also supplies voltage to the coil side of the ASD relay. The Powertrain Control Module (PCM) controls the ground path circuit for the coil side of the ASD relay on circuit K51. Circuit K51 connects to cavity 18 of the PCM connector.
Circuit A142 supplies voltage for the fuel injectors. The PCM controls the ground circuit of each injector, as follows:
^ Circuit K11 is the ground circuit for Injector # 1. Circuit K11 connects to cavity 4 of the PCM.
^ Circuit K12 is the ground circuit for Injector # 2. Circuit K12 connects to cavity 23 of the PCM.
^ Circuit K13 is the ground circuit for Injector # 3. Circuit K13 connects to cavity 3 of the PCM.
^ Circuit K14 is the ground circuit for Injector # 4. Circuit K14 connects to cavity 24 of the PCM.
