IQA Codes are entered into the ECM to improve control of the injected fuel quantity. The code applies over the entire programmed fuel map. The classification codes compensate for deviations in metered amounts, and make fuel quantity metering more precise. The adjustment codes also increase injector efficiency on the engine and improve emissions. Various engine… Read more »
The high pressure pump creates high pressure at low volume. Depending on the system, it is up to the high pressure limit valve, injector connector tubes, fuel pressure control solenoid and injectors to hold leakage and allow the pressure to build.
