Sub Fuel Level Gauge

WARNING: This page is about a different variant/trim than selected.

Check fuel pump assembly for damage.
Check that resistance between terminals [a] and [b] of sub fuel level gauge changes depending on float (1) position.

Check resistance between terminals [a] and [b] at each float position in the following.

If the measured value is out of specification, replace sub fuel level gauge.
