What Does the P059F Code Mean?
The P059F code is a diagnostic trouble code (DTC) that indicates a problem with the Active Grille Air Shutter Performance.
There are a few things that can cause the P059F code to be triggered. All of them mean that, for one reason or another, the vehicle’s chassis control module has detected a problem with the air flow through one or more of the Active Grille Shutters. This triggers the OBD2 trouble code P059F. It’s a particularly common error code to see in the Nissan Altima, and quite a few Chevy models, too.
If your vehicle has been diagnosed with the P059F code, there are a few different ways to fix it. But first, let’s explore what could have caused this error to display in the first place.
What Are the Possible Causes of the P059F Code?
Let’s run through a few of the scenarios that might have your engine light blinking and a P059F diagnostic trouble code showing up on your or your mechanic’s OBD scanner:
- A faulty Active Grille Air Shutter Actuator
- Debris obstructing or impeding one of the Active Grille Air Shutters
- The Active Grille Air Shutter Actuator harness is stuck open or has shorted
- The Active Grille Air Shutter Actuator circuit has poor or faulty electrical connections
How to Fix the P059F Code
When your car’s check engine light comes on, it’s usually accompanied by a sinking feeling in the pit of your stomach. To figure out the cause of the check engine light, you could use your own OBD scanner. This will easily tell you if you are indeed in possession of a P059F diagnostic trouble code. Never fear, though; this particular OBD2 code can be a pretty simple fix in a lot of cases. Here are some basic troubleshooting steps.
The first step is to check for any obvious debris that could be blocking one or more of the Active Grille Air Shutters. If you notice any, simply clear it out, give the surrounding area a clean, and move on to the next step.
Step number 2 is to make sure there are no loose or damaged wiring/connections in the Active Grille Air Shutter Actuator circuit. If you find any obvious damage, repair or replace the affected wiring, or of course, have a professional do it if you do not have experience working with cars.
Once you’ve done both steps, clear the code from your car’s computer and take it for a test drive to see if the problem has been resolved. If not, then you’ll definitely need to take your car to a mechanic or dealership to have them further diagnose and repair the problem.
Summing Up
The P059F Code is an indicator that something is wrong with the vehicle’s Active Grille Air Shutter Performance. Although the code does not point directly to any one specific cause of this problem, it can provide a general idea of where the issue might be coming from. It’s particularly common in the Nissan Altima and a few different models of Chevy.
Common causes of this kind of performance issue include if one or more of the Air Shutters are being blocked by debris, if there are issues with the circuitry in this part, or if the Actuator Harness has shorted or become stuck in the open position.
Fortunately, there are several methods for troubleshooting this issue and determining what is causing it so that you can take steps toward repairing it. In any case, dealing with such codes should always involve professional assistance in order to ensure that the correct repairs are made correctly and safely.
Cracking out your own OBD scanner can be useful before that point, though. That way, you’ll know exactly what kind of problem you’re dealing with and might even be able to fix it yourself without taking it to a mechanic.
