Hello, everyone. I just purchased a 95 240 5spd//. I keep getting code 12. I swapped maf already. I have cut and spliced maf harness connector and car still cuts out and code 12 shows up.

Those are the readings from the maf i got. any info is gladly appreciatedSend To PhoneSend To Phone

its the wiring... check to see if an afc or something was installed (check all the wiring from ecu to maf - there is a problem there)

code 12 can only be - maf, maf wiring or the wires pin at the ecu or maf.

be sure its getting 12v (blk and wht) gnd (blk) and that theres no short for the signal (wht)

if those are mixed up it usually fries the ecu.

That maf is 12V or 5V?

It's 12v. The car runs better no dtc. It runs great. I felt it jerk for a split second but i could not duplicate it. Im going to sader the wires and shield them from emi and rfi
