Intermittent O2 sensor codes P015D & B

[Korndawg]

I have a 2015 1LE. I have had a cold air intake on the car for many months but last month it started throwing the two codes in the thread title. It happened after I went over a pretty harsh bump in the road. I stopped and cleared the code. I drove it for over a week after clearing it and it came back after running over an expansion joint on the highway. I cleared it again and it came back about 4 days later after rolling over a speed bump in my apartment complex. I took it to a dealership that would look past my CAI intake and find the problem, about 3 days later. They told me that their "freeze frame data log" wouldn't communicate with the car's computer, so they cleared the code and drove it around to try and make the light come back on. It didn't after 3 days, so they had me come pick the car up. About a week later it came on again at random. I drove it for a few days after and the light turned off on its own. About a week after that it came back on after running over another expansion joint on the highway. That was 2 days ago.

The dealership i took it to told me that I had to take the car to a dealership to get diagnosed before turning the car off or else their diagnostic machine wouldn't be able to find the fault that is setting the code off. Well I work odd hours and the dealerships were all closed the past two times it had come on. IDK what to do or what would be causing the issue. The dealership said that there were no loose connections or and visible damage to any of the sensors. My mods are CAI brand cold air intake with phastek air scoop and BMR 1.25 springs. I was assured by multiple techs that the CAI would not throw a O2 sensor code. They think there is a short somewhere that is triggered when the car is jarred.

Any one have any ideas as to what the issue is. I don't want to keep taking it to different dealerships and hope they figure out what the problem is. Also, I will not take it to a tuner and have the codes deleted. Its my daily and i don't want to risk a tune voiding my warranty.

What do I need to do?

The newer cars 2015 are more sensitive to changes you will need a custom tune to correct the issue.

Let me know If I can be of assistance.

So I know it’s years later but I’m having the exact same issue. I have a 2014 Camaro SS has the CAI cold air intake for years since 2014. I added the phastex air scoop and not long after got the P105B and P105D. It’s very intermittent turning itself off and on. I replaced the 02 sensors and even changed the spark plugs which looked like crap at 50k miles because the engine is running either way too lean or way to rich. I also have a hesitation when trying to accelerate when the car is cold it will just hesitate and then it gets going. Only codes are the ones above which on a cold car the 02 sensors are not causing the hesitation. Could it be all fuel injector related or is it really just a custom tune?
