Summary
  • The diagnostic trouble code (DTC) P0276 indicates “Cylinder 6 Injector Circuit Low.”
  • The powertrain control module (PCM) will set the P0276 code if it detects a problem with the #6 fuel injector or its circuit.
  • Common causes of the P0276 code are a failed fuel injector, dirty or clogged injector, and circuit problems.
  • A vehicle that sets the P0276 code can show symptoms like an illuminated check engine light, reduced engine power, rough running, and poor fuel economy.

Your vehicle’s engine produces power by combusting fuel. Each cylinder has a fuel injector. When your vehicle detects an issue with the fuel injector in cylinder number 6, the powertrain control module (PCM) can store the P0276 code or other related trouble codes.

What Does the P0276 Code Mean?

The fuel injectors are responsible for spraying the appropriate amount of fuel into the combustion chamber. Problems with fuel injectors typically result in various engine-related symptoms.

How to Diagnose the P0276 Code

If your vehicle’s PCM has triggered the P0276 code, then the likely culprits are the fuel injectors, wires, or the PCM itself. Before performing any kind of repairs, it’s important to first properly diagnose the issue. This will probably involve inspecting the concerned components, which might need special knowledge, tools, or training as these components are often hidden inside the engine bay.

Keep in mind that vehicle designs and their respective repair procedures vary depending on the manufacturer. Diagnosing the concerned components might require special knowledge and tools.

If you aren’t familiar with vehicle repair, take your vehicle to a mechanic for a proper diagnosis. Want to learn more about the diagnosis process? Take a look at the video below.

Before attempting to do any repairs, know that there isn’t a single fix solution for any diagnostic trouble code (DTC) because vehicle models can have different repair procedures. If you don’t have much experience troubleshooting DTCs, then we recommend leaving the task to a professional mechanic.

You can try to do the job yourself, but you need to make sure that you know vehicle-specific repair procedures before you get started. Luckily, this information is available online. Chilton repair manuals or a subscription to an online repair database like ALLDATA DIY can give you information on the correct diagnostic and repair procedure to clear diagnostic trouble codes like the P0276.
