P0207 is an OBD II trouble code. It indicates there is a fuel injector circuit malfunction, in this case,it would be the seventh cylinder that is malfunctioning. P0207 is a generic code, which means that it has the same meaning for the Volkswagen Atlas as it would for any other vehicle.
When the PCM/ECM sees that the voltage from cylinder 7 is outside the normal operating range, this code will be stored in its memory. P0207 is usually caused by a bad fuel injector or a wiring issue. If the misfire were in cylinder 6, you’d get P0206. Since it’s for the seventh cylinder, you will not see this code on a four or six cylinder engine.
P0207 is usually caused by a bad fuel injector or wiring issue.
P0207 Symptoms: Volkswagen Atlas
It is rare that there aren’t noticeable symptoms with P0207. Here are the ones you would be most likely to see:
- Misfire– If your Atlas’s fuel injector is not getting the right amount of fuel into the seventh cylinder, it’ll misfire. A misfire will impact the ability of your vehicle to accelerate, and will cause fuel mileage to suffer.
- Check Engine Light– The check engine light will be on, but you may or may not get a flashing check engine light as well.
You may also get another code, such as one related to the air/fuel mixture, or a misfire code such as P307 (misfire cylinder seven).
P0207 Causes: Volkswagen Atlas
When diagnosing P0207 in your Atlas you only need to look at the fuel injector in the seventh cylinder, since the PCM has pinpointed the location of the problem for you.
1. Bad Fuel Injector
Bad fuel injectors are the most common reason that P0207 is present in your Atlas. You still want to take a look at the wiring harness. You’ll also want to test the injector itself. There’s a YouTube video directly above that shows how to do that. A new fuel injector is relatively affordable.
Fuel injectors can make your Atlas’s PCM throw P0207 if they are plugged, dirty, or defective. This is the most likely cause of this code.
2. Wiring Issue
When diagnosing P0207, taking a look at the wiring around the injector is a great place to start. You want to make sure that it doesn’t look visibly damaged. Make sure that the voltage at the injector matches the injectors that aren’t getting the code. If they aren’t that’s a good indication that something is wrong with the wiring harness.
While it may be more likely that the injector is malfunctioning, taking a look at the wiring only takes a moment and can save you a ton of diagnostic effort.
3. Bad PCM
This is the last place that you’d want to look, but a bad PCM can be the reason why your Atlas is getting P0207.
Conclusion: P0207 Volkswagen Atlas
It’s usually not too hard to track down P0207, thanks to the fact that it is specific to the seventh cylinder. If there is anything you would like to add that could help the next person with their Atlas, please leave a comment. Best of luck!
