Thread: Any suggestions please Disco TD5 owners?

Clean the MAF sensor (CRC have a MAF Cleaner) and check the resistance with on ohm meter.

The data below i plagiarised from another post on AULRO some months ago to keep for future reference. How rude of me not to be able to name the author. Also as mentioned by Hay Ewe get out and give it a thrashing to blow out the pipes. I went into Wonnangatta Valley from the Myrtleford side recently and spent 3 days camping and lots of low range driving on the surrounding tracks, Herne Spur Track was memorable (up and down) Wombat Range Track (up and down) and Harts Spur Track (up and down) and then exit via Wombat Range Track to Mt Cynthia Track to Eaglevale, onto Dargo and home. The drive from Bairnsdale to Dandenong was a joy - the was no holding the beast back - she purred home.

Here's the MAF resistances - as i said above i am not the author

cheers onebob

Resistivity values taken from MAF sensors
New OEM MAF:
Pins 1-2 = 16.8 kohm
Pins 1-3 = ~34 Mohm
Pins 2-3 = ~34 Mohm

Used dodgy MAFs (due being replaced):
Pins 1-2 = 16.8 kohm
Pins 1-3 = 12.28 Mohm
Pins 2-3 = 12.33 Mohm

Pins 1-2 = 16.8 kohm
Pins 1-3 = 19.38 Mohm
Pins 2-3 = 19.34 Mohm

Known dead MAF:
Pins 1-2 = 16.8 kohm
Pins 1-3 = 6.23 Mohm
Pins 2-3 = 6.25 Mohm

From the above it could be concluded that all MAFs, either good or bad, have the same conductivity between pins 1-2 & conductivity between pins 1-3 and 2-3 appears to decrease as the MAF deteriorates.
