P012B code

909 Views 6 Replies 5 Participants Last post by  GreenMachine15
So my 2019 hellcat has quite a few mods and has HP Tuner on it (not tuned by me), but revved the motor up a few times showing off of course and got a check engine with the P012B code. Any ideas on how to diagnose this without taking this back to the performance shop to have them look at it. I have had the car for a year since the work was done and never had any issues, only 16k miles. If I download the HP Tuner software can I clear the code from there and troubleshoot further if the code pops again? Any recommendations? thanks

was the car cold? doesn't sound like a big deal. clear the code and it should be fine. if it wasn't cold maybe air in the system?
