P015B & P015D Codes
As stated in my Title, I've had these codes come up ever since I put on my Cold Air Ramp for my CAI. I had my CAI and Throttle Controller for a few weeks before hand with no engine light.
All that I've done is put on CAI's cold air intake and the ramp to bring in more air for it. I do have a Vitesse Throttle Controller as well. I have taken my Camaro to the dealership (under warranty) 3 times and each time they replaced and relearned the O2 sensors. However the code would reappear within the next 2 days. This has been going on for about 2 months now. The reason I'm just now making this post is because as of recently the engine light has been coming on for a few days, then going off for a few days and coming back. I was wondering if you guys would have an idea of what would cause this? I've tested the throttle controller by having it at 0 for stock, and the engine light still comes on. (will be disconnecting it here soon to see if that changes anything) I have also checked all my connections for the CAI and their all sealed correctly. Thanks in Advance! |

Unfortunately I can't offer any help with your issue, but you may fare better if you post it here. Good luck OP!

Not sure if this will help, but thought I'd share this with ya... My'13 SS recently popped same codes approx 1/2mile after fueling up.
*I've had my CAI intake & Apex scoop nearly 2yrs. *Solo Mach XL catback was installed last Summer. Stock headers/cats. No tune. Never had previous issue or CELs. Fueled up at same Shell station I've always used, & same fuel, "93 V-power". Had no difference in throttle response, noise, or hesitation... just steady Check Engine Light moments after pulling out of the station. Did the obvious first: checked GM locking fuel cap when I got home, then cleaned MAF sensor next day. Even replaced stock fuel cap... Nothing cleared CEL. Took it to Carquest. They verified exhaust tight, cats looked great, & he didn't think it was O2 sensors. Cleared "lean" PO15B & D codes, advising he wouldn't doubt it was just bad fuel mix from station. Gave me a bottle of Lucas Fuel Injector cleaner, which I dumped in tank right away. When fuel was down to nearly 1/4 tank (same tank of possibly "bad fuel"), CEL popped back on again. Headed straight to Chevy dealership in town next day. Tank was nearly on empty, so stopped to fuel up about 5 miles from dealership. Got back in car, fired her up... CEL was gone, all by itself!?!? Still had dealer change oil, & they ran diagnostic check to be sure... No issues found. Have fueled up twice since then (at two different stations), no problems what so ever.

Ok guys, I've had my VTC off of my car for 4 days now and it seems like everything is back to running normal and I haven't had the engine light come back on. (which by now it normally would). So unless something changes in the next few days, it seems like my car just did not like the CAI w/ scoop and VTC combo.

I have the same issue as you. I have a 2014 SS M6 that throws both codes intermittently. It started when I installed the air scoop. The CAI has been on for years no issues. Is the scoop really causing these issues? I’ve replaced the 02s and my mechanic even relearned the fuel maps and check engine light came on showing -6 LTFT and the freeze frame data is showing +29 STFT. I’m at a loss been chasing this issue for over a year

No the car is not tuned. Only mods are a CAI that’s been on since new. I added the phasetek air scoop last year and that’s when the issues started. Replaced the 02 sensors already that didn’t change anything even though that’s the codes are for. My buddy who is a mechanic reset the fuel trims after my o2 sensors were installed and now LTFT are showing -6 and the freeze frame data for those codes are showing +29 always around 1400 to 1600 rpm it will trip but it’s intermittent it may trip in 10 miles or 500 miles.

It was reset by a scan tool. And it’s running lean only under that certain condition if you read the live data it’s not nearly as bad. It just seems odd with really no mods except a CAI and scoop the car would need a custom tune
