Basic error definition

Fuel Injector 2 Circuit Low

Cause of DTC

The Fuel Injectors are supplied voltage from the Automatic Shut Down (ASD) Relay Output circuit. The Powertrain Control Module (PCM) controls the operation of the injectors through a Pulse Width Modulated (PWM) Low Side Driver (LSD). Each injector receives a unique pulse width based on that cylinder #39;s fuel requirements. The PCM determines this fuel requirement by monitoring engine operating parameters through various sensors and then calculating the appropriate amount of fuel to be injected. The optimum amount of injected fuel depends on conditions such as engine and ambient temperatures, engine speed and workload, and exhaust gas composition.
