I got the following OBD code on my 2000 Rodeo:
P0463 Fuel Level Sensor Circuit High Input
At the same time the CHECK ENGINE light came on the low fuel light
blinked. Fuel gage was reading somewhere below 1/4. I filled it up
and it took 11 gallons, which makes me thing that the gage was reading
somewhat low. I reset the code and it has been ok for 2 days. Anyone
had this problem and found the cause?
Just had my '04 Rodeo in for the same thing. My low fuel light was on
and I could only put in about 12 1/2 gallons (19 1/2 gallon tank).
Replaced the fuel pump assembly to fix it. we'll see if the fuel guage
reads correctly now, after I drive it for a tank or so. I got screwed
though on 2 points:
1. How do I know that the whole fuel pump assembly had to be replaced
and not just the sensing unit? (Part alone was $276).
2. My Rodeo was only 400 miles out of warranty. Isuzu agreed to be
nice (yeah, right) and cover half the cost of the part, but the labor
alone was more.
Total charge for my repair: $463.26.
Thanks for the feedback. This seems to be an intermittent problem,
which happens when the fuel level is around 1/4 of a tank. It has
happened once again. After a few starts the check engine light goes
out, but the system retains the code. If it were a solid problem I am
sure I could figure it out, but being intermittent the shotgun
approach of just changing out parts can get expensive, as you have
I may hook a digital meter to the +5 vdc feed to the fuel level sensor
and rig it where I can monitor it. If it stays within limits it is
likely the gage unit.
All the best,

I have a 2000 Rodeo that also has the same problem... OBD code P0463
(Fuel Level Sensor High Input). It started a few months back with the
low fuel light and check engine light. My check engine light stays on
and the fuel gage is not accurate. I was hoping to narrow down a fix
before replacing the whole Fuel Pump Assbly. I had a P0401 (EGR Flow
insufficent) OBD code also but dont think it has to do with this
other problem. I will post anything I find out.
