Not Ranked
VE ECM
X1-16 Purple, fuel level Primary.
X1-70 Light Blue, fuel level Secondary.
If you are using a VE ECM, you need two senders.
The inputs are also heavily dampened, so a change in one or both sender resistances does not show straight away.
The ECM also logs DTCs if one sender goes open or short.
Would be easier to use a VZ ECM, one sender.
