Check engine & P015B code
 

Started beast today, exhaust vroom sounded different. Got check engine light, checked for codes and have P015B.
Should this thing go to the dealership now? Or nothing to worry about and just clear?

Believe thats an O2 sensor

Clear and try again. If it returns, you will need a new bank 1 sensor 1 O2 sensor.

Yeah, that’s what the code translates to online. Unfortunately, my Actron code reader will not clear it. It actually shows three codes that are the same thing with the first two as pending and the third as permanent. Looks like a trip to the dealership is in order, hopefully it won’t be expensive as I am just out of warranty.

What do you know… Turned on ignition this morning and Check engine light is off. WTF?
I went to a different place last week for gas, I wonder if it’s possible I had bad yes.

I installed k&N intake do u think the emission system check engine has to do anything with the intake ??

yes

Has your check engine light turned on since you switched gas you used at the time?

nope, haven’t seen it since. Also, haven’t gone back to that Stewart’s shop.

Which gas do you use? If you don't mind me asking.
