2001 Rodeo giving false fuel gauge readings

The gas gauge on my 2001 Rodeo has started constantly moving back and forth toward empty, even when there is plenty of gas. The gas light comes on and my check engine light has been coming on. When I get this checked out by my mechanic, it always shows the same codes. The vehicle has never ran out of gas, but you never really know how much gas you have.

Any help is greatly appreciated.

My 2000 rodeo had same problem . i finally found a bad electrical connection in plug inside the lower left kick panel. the plug connection was not staying fully inserted into the other half of the connector the wire and crimped connector would completley come out of the molded plastic plug that had multiple wires inserted in it . i had to route around to the mating wire on the other half of the connector and connected with a sta-kon connector . there are many connections in this circuit you may have to check all of them. the fuel pump / sending unit did not fix my problem so i went checking connections .this was a fault from who ever made the wiring harness
GOOD LUCK AND MAY GOD BLESS YOU !!!!

Fuel guage sometimes read empty when there is gas in the tank?


Check that there are no holes in the float. If the fuel is getting into the float, it will give a false reading. Another thing is to check the ground on the float sensor. If it's not connected tightly, it will create a false reading too.

When truck is in motion going down the road gauge is all over from empty to full when stoped it reads properly


Your gas tank has a float inside that is kart if tne. Fuel. Pump assembly that indicates the amount of fuel in the tank..it sends a message to the gauge...sounds like the float is sticking when the gas is sloshing around when moving..causing a false read being sent to the gauge. Most times the tank has to be removed to replace..good luck..

We can't put more than $20 in the tank before it starts to over flow, with the gas gauge on empty when we start pumping. Then the gauge reads 3/4 tank. When it runs down to half it jumps straight down to...


Your fuel pump assembly located inside the gas tank has a float that measures how much gasoline is in the tank. False readings means the fuel pump assembly needs to be replaced.

Fuel gage is giving false reason and constantly moving back and forth


more than likely its the sending unit in the tank. if the fuel sending unit is bad, then it will give a false reading. make sure voltage is getting thru wire to tank first. if power change float in tank.

Speedometer and gas gauge are giving false readings!


IT SURE SOUND TO ME LIKE YOU ARE MISSING A GROUND TO THESE GAUGES. THIS WILL BE TOUGH TO LOCATE WITHOUT A SCHEMATIC DRAWING TO HELP YOU. YOU MAY BE ABLE TO LOOK UNDER THE DASH FOR A LOOSE WIRE. YOU CAN ALSO CHECK THE FUSE PANEL FOR THE FUSE MARKED GAUGES TO SEE IF IT IS MAKING GOOD CONTACT. HOPE THIS HELPS. BEST OF LUCK. LET ME KNOW PLEASE. THANKS FOR USING FIX-YA!!!!!!!!!!!!
