P2290 Code: Easy Steps to Solve It
The P2290 trouble code is a diagnostic trouble code (DTC) that indicates “Injector Control Pressure Too Low.” This code is particularly relevant for vehicles equipped with diesel engines, where the powertrain control module (PCM) detects that the actual injector control pressure is below the required threshold. This can lead to various performance issues, including poor fuel efficiency, difficulty starting the engine, and excessive exhaust smoke.
