Title: Temperature gauge erratic + MAF?
Post by harry.m1byt on Oct 14^th, 2006, 11:45pm

Hi again, still trying to solve its niggles -

2.9 12v 1995 auto and 83k.

Tickover is now indicated at around a steady 850 and MPG much, much better. While working my way around it, I thought to give the MAF a clean down, except I was not able to find it - could someone provide me with a clue as to where it ought to be please?

The temperature reading is quite erratic, constantly moving between minimum and mid way. I pulled off the rubber plug of what I assumed to be the sender unit just above what I assume is the thermostat housing and shorted it to ground. The gauge stayed on minimum both with it OC and SC - is there a known common problem with the wiring, connections or the gauge itself?

The trip computers outsdie air temperature just shows '- -' all the time. The dash diagnostics seems to indicate that the temperature sender/wiring is open circuit (OC). Could anyone provide a clue as to where the sender unit is located please? My Mk III Granada's sender was clipped into the front bumper, but I can't find it on this one.

Is there a repair manual for the post '95 Scorpio, my local parts outlet suggested Haynes don't have one?

The 12v doesn't have a MAF afaik. :)

And Haynes (or others for that matter) haven't made a manual, which is why this site exist ;D
There is however pdf's of the Ford TIS (Technical Information Software) on the site. Just select servicing and repairs)

That is a tremendous relief, I thought I must be going a little blind :)

I have already found some of these and extremely grateful I am too. I wonder - is there a way to copy all the TIS across to a CD?
