Bank 1

NOTE: These are circuit specific wiring diagrams. For system wiring diagrams, see SYSTEM WIRING DIAGRAMS . For wiring diagram references to PG-POWER , see POWER DISTRIBUTION . For component locations, see ELECTRICAL COMPONENT LOCATOR .

For air to fuel rations sensor 1 bank 1 circuit, see Figure.

Specification data are reference values and are measured between each terminal and ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

For ECM Terminal 16, 35, 56 & 75 Specifications, see Figure.
