Fuel injectors atomize liquid fuel into small droplets to kickstart the fuel combustion process. The powertrain control module (PCM) uses transistors to turn these fuel injectors on or off. If the PCM detects a low voltage signal from the fuel injector in the #2 cylinder, on-board diagnostics will log a P0264 code.
What Does the P0264 Code Mean?
Diagnostic trouble code (DTC) P0264 stands for “Cylinder 2 Injector Circuit Low.”
As the PCM or fuel injector control module (FICM) activates the fuel injector, a solenoid lifts a valve off its seat, causing the injector to spray fuel. Power is usually directed to one injector terminal upon ignition.
The PCM or FICM determines how long the injector will spray fuel by grounding one of the two terminals in the solenoid for a certain amount of time. The longer the injector sprays, the richer the fuel mixture becomes. Meanwhile, the mixture becomes leaner the shorter the injector sprays.
Note: The definition of code P0264 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 P0264 Code?
- Faulty fuel injector
- Clogged or dirty fuel injector
- Fuel injector control module failure
- Wiring issues
- Powertrain control module failure
What are the Common Symptoms of the P0264 Code?
- Illuminated check engine light
- Decreased engine performance
- Excessive fuel consumption
- Rough running engine
- Engine stalls and/or is hard to start
How to Diagnose the P0264 Code
DTC P0264 is a generic powertrain code that can be logged in vehicles that have an OBD-II system. However, keep in mind that the steps for diagnosis and repair can vary, depending on vehicle specifications.
In most cases, diagnosing trouble codes requires using a scan tool, and inspecting the affected system for any sign of damage. If you think you can’t handle the task alone, it’s best to bring your vehicle to the nearest repair shop and have a trained professional take a look at it.
But if you’re confident enough in your DIY skills to do the job alone, here’s a short video you can watch to get an idea of what the process might involve.
How to Fix the P0264 Code
Without the right tools and technical information, it can be confusing to resolve a code like the P0264. It can even lead to more damage and expensive repair costs if done incorrectly. Under these circumstances, it’s best to bring your vehicle to a trained professional to ensure that all steps and protocols are followed correctly.
But if you’re a seasoned DIYer with experience in fixing DTCs, then you’re well aware that there’s no such thing as a magic bullet that will resolve all codes for all makes and models. So before you work on your daily driver, make sure to consult guides like those from Chilton or an ALLDATA subscription to get vehicle-specific repair information.
