Discuss the causes and fixes for P059F Chevrolet OBDII Code

  • My Chevy impala 2016 is reading a code P059F.. what is this code and how do I fix it

  • The P059F means that the Active Grille Air Shutter Actuator (the vent if front of bumper) is not working properly. Have you remove for any reason the front bumper?

  • I have a 2014 Malibu LS that is throwing the PO59F code, but there is no active grille air shutter on this car. I turn the code off, it comes back on after a few days.

  • Unfortunately, I have never seen that problem. Have ever been in an accident? or had any major parts replaced?

  • No accidents and it didn't do it for the first 3 years of the car.

  • Looks like you may have to take it to the dealer for this one, they may have to reprogram the Powertrain Control Module, I don't see any other component triggering that code.

  • Do you think if I disconnect the battery, the PCM would reset?

  • Disconnecting the car battery for about 30 minutes will definitely reset the code, but may not have any effect on the PCM program.

  • The diagnostic tool I have makes it easy to reset the code, so I won't bother with disconnecting the battery. The code is back on. It doesn't seem to affect the performance of the car. I'm just concerned with passing the Ohio echeck. I've looked for a possible open electrical connection where the Active Grille Air Shutter Actuator would be if I had it on this car, but I don't see any.
    I'm starting to see more people complain about problems with this code and you know most people usually don't go to a website to post about it.

  • What happens if you don't fix right away ?

  • It depends. If the shutters are closed, it may overheat the engine, if the shutters are open it may reduce the engine power, but it may not be noticiable. I suggest opening the shutters.
