Def Injector Not Working at Carl Murphree blog

Def Injector Not Working. Regularly inspect and clean injectors and sensors. These sensors, along with injectors, can fail, leading to incorrect dosing of def and potential damage to the catalytic reduction system. Recently got def injector fault, tested. Topping up your def system with hard water can also result in scale or deposits forming. The injector receives reductant from the reductant pressure. This can often cause your truck to go into limp mode and give you engine codes. An improperly working def injector will cause your truck to display a check engine light or reductive fluid quality message on your dash. The systems rely on sensors to monitor fluid levels and quality. Contaminated def can cause abrasion of the def pump. The injector also has a delicate plastic line. Replace faulty sensors and injectors as soon as issues are. Common def issues include contamination, freezing in cold temperatures, quality concerns, incorrect def levels, pump and injector problems, and tampering. Reductant (def)injector • the reductant injector is a pulse width modulated (pwm) solenoid controlled directly by the pcm. These issues can lead to warning lights, reduced engine performance, and increased emissions.
