Would an airleak PAST the MAF cause an IACV check engine?

I was getting a P0505 (IDLE AIR control valve) code on a 95maxima with 205K miles. But idle under all conditions was fine.

I cleaned the connectors and so far, it has not comeback on - BUT I later found this ‘insulator’ was bad and leaking air after the MAF - http://www…28908.html

(see figure for part #16523). It has since been replaced.

Is it likely that would cause a IAC code?

Yes. Any leak after the MAF sensor will cause a P0505 DTC.


thanks - I was figuring it would be related. Smoothsailing.
