Question about 2002 Isuzu Axiom
WHEN I FILL UP THE GAS TANK THE LOW GAS SIGNAL FLASHES ON THE INSTRUMENT PANEL.
Tips for a great answer:
The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than 14 percent, the low fuel indicator illuminates.
The best place to start , instead of guessing , would be to hook up a GM factory scan tool ,Tech 2 scan tool ! This would be done to see if the PCM is receiving a voltage signal from the fuel sending unit in the fuel tank . An to see if it is sending a signal to the instrument cluster .
Don't get me wrong here , there are other ways to check it ! The PCM supply's the fuel sending unit with a 5 volt reference voltage , the sending unit is what they call a potentiometer ,with the level of the fuel , it will send back a voltage signal less then five volts . The PCM will know what the fuel level is by that voltage an send it to the I / P cluster . There are videos on you tube on how to check it ! You can go to radio shack or some other electronics store an purchase different resistors ,Then find connector C-413 C413 -- 16 cavity
Fuel tank/canister vent/wheel speed sensor harnesses to body harness, under the right rear of the vehicle, near front of the gas tank. We have a special tool here at the dealer ,a signal generator
Connect the J 33431-C Signal Generator and Instrument Panel Tester between the signal circuit and the low reference circuit of the fuel level sensor on the male terminal side.
Then install the resistors one at a time to check different fuel levels , one for 1/4 , 1/2 ,3/4 an full ! Good luck hope this helps
