P0205: Cylinder 5 Injector Circuit Malfunction

Your vehicle’s fuel injection system sprays atomized fuel into the cylinders or intake manifold of the engine. It is equipped with circuits that move the injector’s valves to an open position.

Code P0205 can be logged when your vehicle’s powertrain control module (PCM) detects an issue in the Cylinder 5 injector circuit. Read on to learn more about this diagnostic trouble code.

What Is Code P0205?

Diagnostic trouble code (DTC) P0205 stands for “Cylinder 5 Injector Circuit Malfunction”. Usually, a P020x code will correspond to a cylinder, i.e., “P0204” for “cylinder 4” or “P0205” for “cylinder 5.”

Modern vehicles are equipped with fuel injectors. These injectors supply atomized fuel into your engine’s cylinders or intake manifold. These injectors help your engine achieve the right air-fuel mixture to keep your vehicle running.

Usually, a P020x code will correspond to a cylinder, i.e., “P0204” for “cylinder 4” or “P0205” for “cylinder 5.”

Your vehicle’s PCM monitors the operation of these fuel injectors. If they are activated, the voltage should read “low” or close to zero. When switched off, a high reading is expected.

Code P0205 can be triggered once the PCM detects that the injector’s voltage in Cylinder 5 does not match its current state (activated/switched off). It also means that the voltage and resistance are not within range.

Note: The definition of code P0205 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What Are the Common Causes of the P0205 Code?

• Malfunctioning fuel injector in Cylinder 5
• Open  or shorted wiring to the injector

How to Diagnose the P0205 Code

Although code P0205 is a generic powertrain code and may indicate similar triggers and symptoms, its diagnostic steps and repair procedures may vary per vehicle manufacturer.

If you’re not familiar with the process of diagnosing trouble codes on your own, it may be best to let a certified mechanic do the job for you.
