i don't remember. but my question is, what could cause my maf to go or not work properly? I mean I just got it yesterday plugged it in and nothing. I bought a used aftermarket one about 2 months ago. it worked for those 2 months and went.

Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you

it could be defective out of the box, or, it could be getting contaminated immediately due to some sort of oil or dirt having made its way into the air intake tract. or, the ecu could be bad, or there could be a wiring issue of some kind.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
