After Replacing Air Filter I received:
Hill Descent Control Fault
Service Advance Track Fault
Wrench Fault
Check Engine Light

I was doing an oil change today and replaced the air filter in the process. Everything looked good before I replaced the air filter but after installing the air filter the Hill Descent Control error, Advance Track error and the Wrench error showed in the display window and the Check Engine light illuminated.


I realized I forgot to reattach the wiring harness to the air filter housing.

I reattached it and started the engine again, the Hill Descent, Advance Track and Wrench errors went away but the check engine light remained illuminated. I removed the battery cable for a few minutes to clear the logs memory and restarted again and the check engine light did not illuminate.

I just wanted to make note of this here in case anyone runs into this issue. The errors were very unhelpful (and somewhat stressful at first if I am being honest).

If you are replacing your air filter and take off the wiring harness, don't forget to put it back on before you start your engine. :)

Hope this helps someone out there!

Did you clean your MAF while your filter was off?

Not this time around. I will probably clean the MAF (Mass Air Flow sensor) on my next oil change since the engine starts fine and idles smoothly right now.
