Fuel gauge showing half full when empty

Hey guys. I have been working on getting my tachometer working and have finally got it back in and fully functional after finding some broken solder joints. I accidentally bumped my gas gauge needle when reinstalling the clear lens on the gauge cluster and now it reads 1/2 tank plus always. When full it reads past the F. I’ve tried positioning the needle where I believe my fuel level is no avail. My fuel light works which is great but I’d really prefer my gas gauge to work correctly. Any help is welcome. Thank you in advance.

If I couldn't get it to reset I think I'd wait until the fuel light came on and put a mark a quarter of the way above where the needle is so I'd have an advanced warning.

Just as a thought can you spin the gauge itself from behind, that might work, forget the needle, turn it all.

Not a bad thought but I believe there is 2 screws that hold it in place. Almost thinking maybe the voltage regulator in the back of the gauge itself was damaged and now is reading double the actual level instead of empty where it should be.

Hi - there are some trouble-shooting tips in the repair manual - checking resistances etc.

It's in the downloadable manual set that's predominantly for the petrol 2RZE engine version and the earlier 'L' diesels, but I would think it would be identical for the 1KZs too - as I believe they use the same dashboard combination meters.

It's available at the hiace south east website:

go to the RZ-LH series manual, then chdck both of these. i think there are different pages for different editions:

Repair Manual : 10 Body Electrical : 10 Combination Meter (pages BE52 and BE53)

Repair Manual : 10 Body Electrical : 11 Combination Meter (page BE15)

and also double check the diagrams on:

Repair Manual : 20 BODY ELECTRICAL : 6 COMBINATION METER (all) to double check you have the right diagram to match your van.
