- VX V6 wagon 5sp Manual
Have searched this but can't find info I need; Does anyone know how the Litres in tank is read - is it the sensor, or is it calculated from usage?? If it's the sensor, then I have a doozy of a problem...
The car (VX 1, executive manual V6 wagon) has been running normally in respect of the electrics for at least a year (haven't owned it any longer than that ); after I parked facing up a slight hill, (I knew I had a little under half a tank of juice) - when I got back in & started the car, the low fuel warning activated and display (single window) switched from "trip meter" to "distance left before empty", showing 4Kms. I went about 100 metres & pulled over, switched off completely then switched on using the "up" & "mode" buttons to get me the diagnostic info - cycled through readouts to find it was reading ~30Litres in the tank, which was about what I expected (?!?!)
The Fuel Warning was still active even after this off & on sequence; then I switched off & on to get normal display back, low warning still active, but fuel gauge verrrrrrrrrry gradually climbed back over the next 5 minutes to where it should have been..... WTF?? Haven't driven the car since, but will keep an eye on this now...
1) I would love to know why this is happening but suspect the cause won't be known...
2) How can the Litres read accurately on the display window in diagnostic mode, yet the gauge reading is screwed ?!?!?! - and then gradually changes back to what it should ?!?!?!?!?! - Hopefully a Holden Tech-savvy person can answer that one!!
I have EFI Live on my laptop which I'll be hooking up tomorrow to see what DTC's (if any) exist...
Cheers,
Brian
