Check and post your codes again I can't find a P1278 for an 04
Not trying to be an *** but P2067 is in 2004 manual.
No listing in the index but it follows in pages after
P1431 Fuel Level Sensor 2 Circuit Performance
P1432 Fuel Level Sensor 2 Low Voltage
P1433 Fuel Level Sensor 2 High Voltage
P2066,P2067,P2068 Refer to problems with right fuel sender
P2067 easiest description is the right tank sensor is sending a lower signal than normal.
Clear codes. Try adding Techron fuel additive. It did not work for me. Diagnostics get in to checking for lose connections, to pulling the right fuel sender and R&R right fuel tank assembly. Hopefully you have warranty I had warranty and they supposedly had to replace both tanks and crossover pipe. Been 3 yrs since new tanks no problems.(knock on wood)
