    Hello,

    Does anybody has experience this DTC while scanning the car? I erased all the DTC's (had the P2188 & P2190 as well previously, but cleaning the air mass meters and tract seems like didn't help so looks like I will need new ones) and today I scanned the car and got the same DTC as previously, being active the P2188 & p2190 but "missed" the P0721 for the F1 shifting ecu.

    Is there any known issue for this problem to show? Perhaps just plug connector clean and re tight then pins or is a common senosr failure?

    P2188 is Long Term Fuel Trim Additive Air
    P2190 is Long term fuel trim too lean.

    As well as AFM's, check for inlet manifold leaks. Could also be lambda sensors.

    Have you been able to solve this issue and how? I have the same problem on my 599gtb.
