Bad MAF, reading max value?

(1/2) > >>

OllieVRS:
Had this issue for a while now, but need to get it sorted as the old VRS is going up for sale  :sad1: I'll still check in on the forum every now and then to see if anyone needs oil pressure help  :wink:

MAF value on VCDS is reading the max value, no matter it is plugged in or not. Engine is running and pulling like normal, perhaps with worse fuel economy than it should have. Engine light on obviously.

Any ideas?

Cheers

It sounds faulty, as you'd think you'd get a different reading with it unplugged and plugged in.

OllieVRS:



Faulty, but where? Still reading 5V from first pin on the plug. On a healthy car, what value does it read with the MAF unplugged? Thanks  :smiley:

GVK:
Have you checked for continuity along the MAF plug?

OllieVRS:
Thanks for getting back to me.

I've checked first pin, live, is always 5V, the second pin has continuity to negative battery terminal, and the third pin nothing, so I assume data?

I tried getting the ECU out to test too but the annoying b*stard refuses to come out :doh:
