DTC Description: Notes
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
The Fuel Injectors' timing and quantity is controlled by the Engine Control Module (ECM). The ECM provides current to energize the actuator (Piezo) in the Fuel Injector. This causes the needle valve to rise and flow fuel into the combustion chamber. The ECM has an internal injector driver for each Group of Injectors. Each injector circuit has a dedicated low-side switch that completes the circuit path to ground inside the ECM. Electrically, fuel injectors 1, 4, 6, and 7 make-up Group 1. Fuel Injectors 2, 3, 5, and 8 make-up Group 2.
