Vida gave error code ecm-120d, I changed the airmass meter, now the code came back. What next?
Car is XC90 2.4T 2005

Not all error codes in VIDA mean the device is bad

The device reported something bad, but it might be OK
As in your case: there was likely no need to replace the MAF.

Check all your intake system for cracks and leaks.
You likely have an air leak.

A smoke test will help

Google "smoke test intake" and that will give you some ideas.

You can get "smoke matches" https://www.toolstation.com/smoke-matches/p50805

They give off smoke that you can hold near the suspect pipes to see if the smoke is sucked in through the crack/split.

Cheers

Seal off the air intake at the output of the airfilter box using a plastic bag over the pipe.

Disconnect a vacuum line and connect a smoke generTor to the line

Let the intake system get full of smoke.

Look for leaks.
