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 injector timing and quantity are controlled by the Engine Control Module (ECM). The ECM provides current to energize the actuator in the fuel injector. Energizing the actuator causes the needle valve to rise, allowing fuel to flow 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 and fuel injectors 2, 3, 5 and 8 make up group 2.
