P0463 - How to Fix it?

P0463 Fuel Level Sensor 1 High



I just installed an AirDog. Since the AD is pushing more fuel through the system than the stock lift pump, did this trigger the code?

If not, any suggestions on what else would cause a P0463?



After we figure out what caused the P0463, then we can figure out how to fix it.

According to the FSM this code is a fuel gauge sensor issue. Did you use the factory fuel pump harness to activate the AD? Disconnect wires at the tank?



Possibly a bad connection?

Yes, I did connect the AD to the factory fuel pump connection (that's per the instructions). And I did disconnect the wires attached to the tank fuel canister, because I installed the 'tank vent mod'.

I'll disconnect / re-connect the connection plugs and I need to get an OBDii scanner to clear out the codes and see if it re-appears again.

** I cleared the code and it did not come back. Probably triggered the code when I unplugged / plugged in the connector.
