2002 Rav4 gas gauge not working. Can you give me a wiring

Customer Question

2002 Rav4 gas gauge not working. Can you give me a wiring diagram for the gas gauge circuit, please. When I ground the gauge directly (above the tank), the gauge goes way past full, though it is only around 1/4 full. And I am getting no ground for the O2 sensor.

Gauge not stuck.

Expert:  Pete replied 7 months ago.

O.k.,below is the diagram of the gauge you are looking for on this model here.The most common cause is the fuel level sender itself attached to the fuel pump module in the fuel tank,I have had to replace several of these before for this issue here.

What about the O2 sensor ground?

Expert:  Pete replied 7 months ago.

It looks like the oxygen sensors grounds come from the engine computer.They are also grounded when threaded into the exhaust.Below is the diagram for these here.The B-R wire is the power feed wire and all other wires from the sensors go to the computer.
