hi folks i plugged the code reader in on friday nd with the engine ont running i get code 31 no rpm sighal.with the engine running i got this data.
hall sensor off
engine speed pulse yes,
knock signal load no.
mixture 1 lean.
mixture 2 rich..
not sure what to make of it weather it is a crank sensor or something else. :y
I don't know much but I believe code 31 is normal when engine isn't running.
Someone with more knowledge will be along soon.

That's meaningless I'm afraid, as they will vary by millisecond.

Get the MAF readings, and also the BLMs.

Is there a code associated with 'hall sensor off'? The camshaft sensor is a Hall effect sensor. So why would it be 'off' with the engine running?

BLM - Block Learn Multiplier; basically the long & short term fuel trims. (Either expressed as a %age or an absolute number, depending on age of car IIRC)

Re Snapoff scanner. Ours doesn’t work on my Omega.  ::)

As said paper clip is the way forward. Iirc crank sensor is a code 19 but don’t quote me on that.

mine works with no problem.
ok so this is the injector duration its between 3and 3.1 m/s but i belive i may have solved the problem. i put some more fuel in the tank on friday went to start it this morninfg and fired straifght into life and run on fast idle, so i think its either weak fuel pump or the filter is blocked, got a new filter to fit tomorow along with a new rear box which has got a hole in it. so fingers crossed all should be good. ;)

mine worked OK, read all the live data, trans codes etc. Do you have the appropriate key for it? That's how Snap-on  further stitched up buyers of their tools: not only did you have to stump up huge amounts of cash for the scanner, but you needed four figure sums invested in the keys to use the bloody thing effectively. There's probably 3 dozen keys and assorted leads in the box with my now knackered Solus.

MAF looks in right ballpark for a v6 with AC on. Shade high if AC is off (assuming engine warmed up)

If its a 2.5/3.0, the BLMs I'm interested in are the Partial Load two, and the Idle stepper - all on an 8 bit scale of 0-255, midpoint of 127.

If its a 2.6/3.2, The BLMs I'm interested in are LTFT, expressed as a signed percentage, with 0% being midpoint.
