I got these codes

[mustang1994]

I got codes 157,158,564..


I know 157 is Mass Air Flow sensor fault, low voltage
ang 158 is Mass Air Flow sensor fault, high voltage

But I put in a new MAF, is the codes from the old sensor and I just need to reset the computer?

And code 564 (Cars only): Electro Drive Fan circuit fault. Is my electric fan no good if I get this code, even tho it kicks on still?

did you reset the codes after you replaced the maf? if not then those are the old codes. and need to be dumped and driven to see if they come back

I didnt reset the codes, I just put my new MAF in. I just unplugged my battery for the night to reset it. Didn't know it kept the old codes. What about the Electric fan?
