Forgive the vague subject. I have a fault in the engine ECU (Thor), but a look online doesn't seem to tally up with the description on the nanocom, nor do I quite know what the nanocom is talking about other than bank 2:
I presume something has upset it, but I don't know what it's talking about to be honest! Lean, rich, up, down, left or right - ideas?
I'm 99% that was the only fault... but now I'm questioning myself but its too late as I've cleared it to see if it comes back tomorrow.
Well, if my interpretation of the entrails is correct
It's RH bank (sitting in drivers seat), v. lean, happened once, not there at the moment
Run it around for a bit and see if it happens again perhaps?
A check of the O2 sensor numbers and, just for fun, the MAF numbers might show something awry.
Well it didn't come back after the commute this morning (30 miles mixed drive), though I check the MAF at idle and 3000 rpm when I got here, and if the numbers on the nanocom are indeed grams/second, it was reading 21-22 at idle, and about 95 at 3000.
If you 60x60 that, at idle that works out to be 80kg/hour, and 342 at 3000.... that's a bit out of spec, is it not? Otherwise those numbers look a bit coincidental, as I'm sure it should be 20ish kg/hour at idle, and 90ish kg/hour at 3000rpm.
The Nano is Kg/Hr so your MAF is spot on I think. No conversion factor required.
For the GEMS (I don't have the Bosch Nano docs yet)-
Current air flow: This is the current reading taken from the Air FlowMeter. It should be
around middle 20's at idle rising steadily with engine RPM until around 200 KG/HR at
5500 RPM.
I think, as it's only reported that fault code once, historically, just treat it as a glitch and go back to worrying about your servo motors :-)
Seemed too coincidental! Though under the Motronic, the MAF sensor is stated to be 'grams/second' - helpful...
Only really been looking for issues as I seem to have lost a bit of power at the upper end, and the box even in sport doesn't change down quite as far as it used to with my foot in the carpet. Seems to be the same on petrol and LPG. I may also be imagining it however, so I'm not too inclined to go looking much further.
In the "olden days" when I ran a string of garages, when cars came in for a "tune-up" the mechanics would move the drivers seat forward one notch as part of the process. Customers used to rave about the increased throttle response and power compared to the pre service feel!
Perhaps you could try that?!
Or, on a serious note, how about checking that your throttle cable hasn't gone a bit out of adjustment?
Or of course, there's platform shoes, I'm at a disadvantage with them, I'd hit every doorway I went through..
Both here http://www.obd-codes.com/trouble_codes/landrover/ and here http://www.robisonservice.com/servicedep/rover_obd2.asp say that P0175 means band B too rich if that's any help.
I can't get the seat far enough back as it is.
I need to check the throttle cable... my TPS seems to go from 0-76%, at which point the pedal is on the stop. Maybe the cable has stretched or needs some adjustment. I should go and move the butterfly by hand as far as it will go and see what the TPS goes up to.
Hmm, that's a thought! I could do the opposite and keep my wife out of the hedge...
The Nano manual for the Bosch says:
MAF sensor: AirMass Flow Rate in Kilograms per hour. This reading shows the amount
of air which is being used by the engine. Under most conditions this will indicate the
current power output of the engine.

It lies! Definitely says 'MAF Sensor (g/s)'
If only I had a Motronic to test it on :-(
Patience dear boy, patience......
Hah!
Got the Motronic licence for the Nanocom. I'm all dressed up and no place to go...
