    P101 Code after installing Krona 3in turbo-back exhaust

    Good Evening SW,

    Picked up a Krona exhaust system(turbo-back), installed bungs for the o2 sensors (up and down stream) and my lovely Aero keeps throwing p101 codes at me. Its the only fault. I have the exhaust lock nutted to the exhaust manifold, is p101 a huge issue worth getting another MAF for, so is it more of an annoyance?

    Thanks!

    You put in a turbo back, installed your own bungs and p101 is your only fault. That's kind of impressive, not an easy thing to do without a hoist.

    P0101 is an insidious little issue that if left un addressed can cause problems and you might actually need a new sensor. But you had to move some plumbing to get your hands onto the turbo and more than likely have an air leak someplace in the line. Maybe something you leaned on, or over, while doing something else. Make sure your plumbing is air tight before you spend money on electrical parts.

    I second the checking of the bung holes and assorted plumbing for leaks. Tighten sensors again.

    It's not good to have a leaky bung hole.
