Check Engine Light after Filling-Up
Posted on 5/17/21 at 11:22 am
Posted on 5/17/21 at 11:22 am
Anyone have an idea why a car's check engine light would repeatedly show after a fill-up, only to go away after burning roughly a quarter-tank of gas?
I've experienced this issue for a while, now. I've visited different gas stations and changed the fuel cap, to no avail...
The code is related to the oxygen sensor, but that's already been replaced.
We're talking about a 2013 Nissan Sentra, in this case.

Probably your gas cap seal.
ETA never mind. Looks like you checked that.

What's the code that it's throwing?
Buy an OBII scanner tool or take it to AutoZone or a Napa where they will pull it for free.

Take off the gas cap and put back on. Will likely fix it.

Probably your motherboard for the O2 sensors.
That or you didnt replace all of your O2 sensors with the last repair.

What's the actual code? Some are for a sensor issue, other are for A/F out of range.

gas cap is loose. Takes a few stop/start cycles to reset. Is there a missing gasket for the cap?

When you fill up, do you stop when it kicks off or do you keep squeezing the handle until it over flows?
Its a known issue that people that overflow their tank saturate the filter in the the neck of the tank.

should add make, model, and year to the OP

Can you post the make and model of the vehicle and the code that you're getting?
Cars have multiple O2 sensors.

EVAP sensors or EVAP canister is/are all bad

Chevy's are notorious for the gas tank vent solenoids or tank purge valves going out, especially the trucks. If you have a hard time filling up with the pump continuously clicking off, it's usually one of those 2 things. The engine light will go out after fill up sometimes but usually come back on for good later.

Evap canister likely. My Frontier did the same thing. Eventually it wouldn't let me add gas.
It was a very simple replacement, took about 10 mins with novice level skill and basic tools.

Fuel canister attached to your tank likely isn't venting and/or is leaking.
Posted on 5/17/21 at 11:54 am to Hoodie
Yes, but it was because we were filling up with the truck/car running.

I'll tell you what idea I have.
You are going to pay $150.00 to get it fixed so you can then pay $60.00 for an inspection sticker.
Then the light will come back on in three months

I had this issue with Sams club gas. Switched to Shell and Costco and the issue stopped. Do you always by gas from same station?

There were two nearby convenience store gas stations I'd go to every now & then, and the light would always go off.
A mechanic told me it was their "cheap gas", and the light will go off once the tank is gone and refilled with gas from a dedicated station, like Shell or Exxon.
Sure enough, it was true. I don't use convenience store gas anymore, and the light hasn't gone off since.
