2006 zxw 2.0l 5speed.
No code other than air bag and t-stat related.

The fuel gauge in my car isn't working properly. When full it reads between 1/2 and 3/4 full.
It's not the gauge, I've swapped clusters with the same result.
Ive done some searching. Some cases its the cluster. Other cases its something else.

Can someone tell me what is usually the cause?
Wiring? Fuel sending unit?

Most of the time the cluster gauge is OK, usually it's the sending unit on pump inside tank. If ethanol used in your local fuel even more that. The ethanol tends to corrode the sending unit resistor tracks.

Thank you for tbe responses.
From my searching, the only real solution that ive found was replacing the sending unit and pump, correct?
