P0205 on Chevrolet
Injector Circuit/Open - Cylinder 5
P0205 on Chevrolet vehicles indicates injector circuit/open - cylinder 5. Au7o has documented this code across 1 Chevrolet model — most commonly on Silverado 2500HD. 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. Typical repair costs on Chevrolet range from $100 to $800, depending on the specific model and root cause.
Common Causes of P0205
- •Failed or open fuel injector on cylinder 5
- •Open or shorted wiring in the injector control circuit
- •Corroded, loose, or damaged injector connector
- •Poor power feed or driver fault from the PCM/injector circuit
- •Chafed or broken injector harness
- •Blown fuse feeding the injector bank (where applicable)
- •PCM injector driver failure (less common)

- Injector Wiring Harness Chafing (Duramax)2001-2016
The fuel injector wiring harness on the Duramax diesel routes across the top of the engine under the valve covers. The harness rubs against the valve cover and rocker arms, causing the insulation to wear through and the wires to short or open. When an injector wire is damaged, the affected cylinder misfires, the engine runs rough, and white smoke pours from the exhaust. The chafing is accelerated by engine vibration and can affect multiple cylinders over time. GM released updated harness routing clips but the fundamental design has the harness in a high-wear location.
