Discovery 1 MAF 14 CUX

Hi guys, anyone has experience with discovery 1 , V8, MAF - 14 CUX. Car is running very rich black smoke and huge fuel consumption. When checked the reading from MAF on idle it is 12 to 13v which is very high. it’s supposed to be 1.3 to 1.5v. Appreciate any leads what need to be checked next….

I have checked with 3 different MAF’s

Unplug it and leave it to the side.
Tape up the hole in the pipe job done...

You mean to disconnect the MAF ?

Hi, make sure that you measure between ground and the blue/green wire not on the supply(brown/orange) and if on blue/green you get that 12V with all 3 MAFs means there is a short in the harness to battery supply. Disconnect the MAF and measure in the unplugged connector to blue/green wire as well then report the result
