P0205: Injector Circuit/Open - Cylinder 5
4 vehicles · 3 makes · $100-$5,000 repair
Most Reported On
P0205 is an OBD-II diagnostic trouble code meaning “Injector Circuit/Open - Cylinder 5.” P0205 is a fuel-system code meaning the engine computer detected an electrical problem (an open circuit or out-of-range condition) in the fuel injector circuit for cylinder number 5. The PCM controls each injector with a precise electrical pulse, and it monitors that circuit for proper current flow. When the cylinder 5 injector circuit doesn't respond as expected — typically an open or a wiring fault — this code sets. It generally causes a misfire on that cylinder, rough idle, hesitation, reduced power, and possibly hard starting, since cylinder 5 isn't being fueled correctly. This code is most commonly reported on 2017-2023 Ford Transit, 2001-2016 Chevrolet Silverado 2500HD, and 2015-2024 GMC Sierra 3500HD, plus 1 other vehicle, with repair costs ranging from $100 to $5,000.
