Speedometer, odometer and fuel gauge not working

Hello,

The speedometer is controlled by the vehicle speed sensor (VSS).
The VSS is located on the top of the transmission housing (see diagram below).
The VSS works by measuring the rotation of the transmission shaft and sending that signal to the ECM, then the ECM converts that to the gauge read out that you see.
Check the connector for that sensor. Make sure it is getting power and is clean. If the connector is secured but the gauge is not functional then it is a bad sensor.
Replacing this should also fix the odometer.

The fuel level is not functional likely a faulty fuel level sending unit located in the tank.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
