Hello,

my fuel gauge suddenly went to empty-
gas tank is full of gas, I don’t know if this is a sender problem or another issue, but it was not malfunctioning before at all.

I did change the fuel pump about 3 weeks ago, and everything has been fine since

Any ideas? Is the sender in the tank just bad?

thanks !

Dell, I was getting ready to post on going into the diagnostic mode and doing that very check. That will tell the poster if the sender or the computer is bad.

 

Thanks for the replies. There are several (4) FP settings and they all show between 208-253 ….. There is one that says FG 1 but that’s it

 

So your FP all show good, what was the FG reading?

Should have 2 =

Fuel gauge 1 FP XXX Fuel gauge 000 – 254
255 Displays present damped total fuel level percent status in decimal
000 – 254=Normal range
255=Open/Short detected

Fuel gauge 2 FG XXXX Fuel gauge N/A Displays fuel gauge driver counts in decimal

Fuel pump =

Fuel system 1 F1 XXX Fuel indication system 000 - 009
10 - 254
255
--- Displays present received fuel level input 1 in decimal, fuel gauge will indicate present filtered level
000 - 009=Short Circuit (below empty)
10 - 254=Normal range
255=Open Circuit (over full)

--- = Missing Fuel system 2
F2 XXX Fuel indication system 000 - 009
10 - 254
255
--- Displays present received fuel level input 2 in decimal, fuel gauge will indicate present filtered level
000 - 009=Short Circuit (below empty)
10 - 254=Normal range
255=Open Circuit (over full)

--- = Missing Fuel system 3 FP1 XXX Fuel indication system 000 – 254
255 Displays present filtered Fuel level percent status from sender 1 in decimal
000 – 254=Normal range
255=Open/Short detected

Fuel system 4 FP2 XXX Fuel indication system 000 – 254
255
NC Displays present filtered Fuel level percent status from sender 2 in decimal
000 – 254=Normal range
255=Open/Short detected
NC=Not configured/option not present
