problem is Lanci Delta with Fiat 2.0 16v multijet diesel engine,170 bhp,2009. year.The car have specific problem.During
decceleration ONLY car goes to limp mode becouse ECM register DTC: P010F-air mass/air flow meter incongruence.Beside that car doesn't have any other issues,dtc or any driveability problems.
I have checked air leaks and didn't find any faults.
I scope MAF and I didn't find anomaly in signal.It looks very fine to me.
I suspect that maybe air filter make some kind of air disturbance to measurement element of MAF sensor...
Any other ideas or need for more info about car or problem?
Best regards Dejan
