Hi everyone,
I have a Lancia Lybra with a 1.9 JTD engine (AR37101) 110HP.
Although it is working fine, I have a persistent fault code, P0638. I can't clear it. It means Air flow modification throttle not working well.
I would like to get rid of this code. Do anyone know what would cause this error? I tested the throttle via multiecuscan and it looks the flap closing fine. Is there anything else, another flap? I have changed EGR valve and MAF in april.
Regards
Balázs
