Car misfiring and stalling?

Hello I’ve been having trouble with my car shaking and stalling. Yesterday while I was driving and coming to a red light, my car started to shake and it stalled on the road but didn’t have any issues turning back on. The air conditioner was also running at the time though the car will also start shaking when it’s off. The car only shakes while I’m stopped at a red light with my foot on the brake and transmission still in drive. It started to shake again that same day when I was held up in traffic so what I did was put the transmission in park and it all of a sudden stopped shaking. I took my car to autozone to get the battery checked but there was no issue there. I also took my car to a friend that has a scanner tool yesterday and though I have no check engine light on my dash 1 fault code was displayed on the scanner screen that read “ code: P05A1:00-6C CMDTCs active grill air shutter A Position sensor min/max stop performance. Could this code be why my car is shaking and turning off? If so can someone point me to the direction of what part I need to resolve this issue. Thanks in advance.
