Civic GX: the fuel door indicator llight flashes and the fuel

Customer Question

the fuel door indicator llight flashes and the fuel level decades down to 0. I replaced both low and high pressure filters. the problem is still there. I can reset the comp and resolve the issue. But if I let the car sit for over 2 hours, the issues returns. if I reset the comp and turn the car off and turn it back on within an hour, the problem is not there. The car runs OK either condition of the indicator. Any ideas? 2007 GX with 175k miles.

Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
MY apologies for the delay, thank you for your patience.
Is it the low fuel indicator (the light above the E letter on the fuel gauge)?
And how are you resetting it?
Customer: replied 2 years ago.
The fuel level is at the 3000 psi mark.
I reset it with a CEN-TECH code reader.

It is the low fuel indicator. I cannot read any fault codes with my reader.

did you check the fuel gauge sender (or its connector) in the reservoir?

This is a natural gas (gx) civic. This has happened before. I changed the low pressure filter and that solved the problem. But not this time.

Hello,
Ok, this is the CNG version.
In this case, i will opt out, and have another expert look at the problem. My apologies for the inconvenience.
PS: i think that there's a software update, that should fix this issue, i would call dealer to confirm.
Regards,
Billy
