P0207 Code: Injector Circuit / Open – Cylinder 7

Many modern vehicles are equipped with fuel injection systems that control fuel injection operation via the powertrain control module (PCM).  These electronic fuel-injection systems use relays and wiring to operate.

P0207 is an error code that’s related to your vehicle’s fuel injector circuit. Here are a few things you should know if your scan tool retrieved this code.

What Does the P0207 Code Mean?

Diagnostic trouble code (DTC) P0207 stands for “Injector Circuit/Open – Cylinder 7.”

Fuel injection systems allow each cylinder to receive its own dose of fuel and have the appropriate air/fuel ratio changes according to the engine load. The system uses fuel injectors which are pulsated by the PCM via the PCM microprocessor.

When the injector is activated, the PCM expects that the voltage signal sent is “low” or close to zero. If the injector is switched off, the PCM expects to detect a voltage that is “high”.

If the PCM is unable to detect the correct amount of voltage from the cylinder 7 injector, the P0207 code may be recorded. This could point to an issue with the injector wiring or the injector itself.

If the PCM detects an excessively low or high resistance from the injector circuit, it can also report the P0207 code.

Note: The definition of code P0207 might 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 P0207 Code?

• Bad fuel injector
• Malfunctioning powertrain control module (PCM)
• Wiring issues

What are the Common Symptoms of the P0207 Code?

• Poor engine performance
• Increased fuel consumption

How to Diagnose the P0207 Code

DTC P0207 is a generic powertrain code that can be logged by vehicles equipped with an OBD system. However, each vehicle may exhibit different symptoms. This also means that the steps for diagnosis and repair may vary depending on the specific year, make, and model that you own.

Take your vehicle to the nearest auto repair shop if you’re not familiar with diagnosing trouble codes. If you have the technical know-how to get the job done, then you can go ahead and do it yourself.
