Hi Paul I love your videos I got your book on my laptop I join your prem. channel but it expired and I didn't take full advantage of it that year I had it. I go back when I have time. But you and Eric are the best.
Ok my Question is I watch your video about the P0463, and did somewhat what you did I got to go back and jump the sensor wire with the connector plug in. I believe its the sending unit or a bad connection at the sending unit. I know its not the gauge because
I hook it up to my scanner and was able to control the gauge with the scanner so that tells me the gauge is working and the PCM has control. also my scanner on the data screen shows a 5 volt reading so I disconnected the plug wire at the sensor I took a reading at the sensor wire it read 5 volts then I took a reading at the ground wire and that was good but when I shorted the two wires together at the sensor unplugged I thought I would see 0 volts or near zero on my scanner but it only drop to 4.5 volts I also thought the fuel gauge would go to full but it didn't move. I need to go back and do the same test with the sensor plug in. Now I move on to something else and was checking for misfire on the truck and after I started the truck after a few seconds the fuel gauge went to full like it was shorting out then when back to empty. I check the scanner again it still reads 5 volts. I can still move the fuel gauge with the scanner. so what's your thoughts ???
Another question is the fuel sensor in the tank is solder to the variable resistor and this is in gasoline and not sealed how come it doesn't short out the circuit ?
