Default Gas Needle

Hi All.

I have GX470 2007 (100k miles) and last weekend I noticed that I drove 60 miles (on streets) and gas needle was down to 1/2 of tank. When I went to gas station to fill up, I was able to get only 5 gallons and tank was full. I drove another 45 miles (on the high way), and needle already was down to 3/4 of tank.

I did not have this problem in the past. I was getting 12-14 miles / gallon on the street and 20 - 21 miles / gallon on the high way.

Is anyone familiar with this situation?

Thank you in advance.

Could also be the sender that is inside the tank. Not sure how to test this, but I suspect it involves putting a voltmeter on the wires and seeing how the measured voltage compares with what the factory service manual says it should be.

Try disconnecting battery for a reset. I usually show a range of 260 miles after a fill up. After I do the battery reset the range goes up to 349. Then a drive the actual MPG is recorded and the range will lower to what my MPG actually is. Of course you will have to reset windows sun roof
seats and radio stations

Recently, I have Timing Belt and Water Pump changed. I am sure that battery was disconnected for more tha 5 minutes. I drove like 150 miles since them. Should I continue drive and see what happens?

Thank you

Are you sure they disconnected the battery. Did you have to reset your radio stations? Sometimes the dealer may have used a plug in device through the obd connector to keep your settings. I would say drive it till you really need gas and see what the reset range reads

I am sure battery was disconnected (all previous destinations disappeared and had to reprogram sun roof).
