240 Wagon 1992 Air Mass Meter Problem
 

I am throwing a 1-2-1 code, I think it's just a computer glitch. I removed the code and it didn't come back.

Easy for you to replace.

Were they rebuild ones?

Nope, not rebuilt, every single one was brand new from Volvo.

Check the Valve in the bottom of the Air box. I have seen them stick close and cause the Mass Flow to burn up.

Then valve is the one for the Heat rise setup.
