Merry Christmas everyone.

After pulling the P1121 code I’ve installed a new MAS and ran the live data on my OBD and screen recorded the feed. I cleared the code from the system after I got back from driving but got a phone call and didn’t go back.

lots of activity compared to the last one. I’ve uploaded it to my YouTube page. If anyone can read these and let me know how it’s going, It would be greatly appreciated!
