Gas Level Sensor By doyso (Read 773 times)

The gas gauge goes all the way to full and stays there even with new sensor...manually adjusting it from full position to enpty etc. Does this have something to do with one of the three wires...e.g. disconnecting one of them?

Question How many Wires does the PLUG from the harnes HAS AND how many wires on the Sensor? Some have 2 wires some have 3 wires. So when you get a new gas gauge sensor you have to get the correct one TO MATCH THE PLUG FROM THE HARNESS.

You may have gotten the wrong Sensor if you say you disconnected one wire.

Three wires on both. I tried a brand new sensor and the same thing happened...it went all the way to full and stayed there even though the tank is not full.

Well that could be that the Float is not adjusted correctly. Take it out and when it is out turn the key on and move the float up and down and look at your gauge. If it registers good then you need to bend the wire to adjust it.

You can estimate by holding the sensor along side the tank and bend the wire so that when the gas level is low it registers in the ALMOST EMPTY POSITION. that way when it registers almost empty you have about 30 or so miles before running out of gas.

Now most will register full for quite a long time because on most the FLOAT is actually SUBMERGED WHEN FULL. They will start to register once the GAS LEVEL gets below the SUBMERGED FLOAT and the float then actually is floating on top of the gas.
