P0102 need help
My car threw a p0102 code. It’s a zr1 heavily modified and I’m going to tune tomorrow. It only show the code When I get in it spiritedly no crazy pulls as it’s not fully tuned m. It just has a start up tune. I have 12v at the MAF on the pink wire but I do not show 12v on the ground wire which from what i found online I should have

How EXACTLY did you check the ground ??...it is probably like my C5 which is a body ground...to correctly check a ground you have to “LOAD” the circuit...you can use a 12 volt test light connected to battery positive and touch the tip to the ground terminal on the harness...I use different headlight bulbs of different amperages to check ground...yes the pink wire is power and the yellow should be your signal wire !!...you most likely have a bad ground causing the P0102 !!
