NCFocus12 The easiest solution: stop buying fuel at Costco. How many brain cells does it take to figure this out? Are you a glutton for punishment? CostcoMurphySheetz all buy the cheapest pipeline piss of the day, and truck it in. Basically, the equivalent of buying discounted just-expired meat at the grocery store.

Do yourself a favor, run either Shell or BP, or I suppose Chevron if you have it in your area. How much are you really saving going to Costco? 50 cents every 300 miles?

I once made the mistake of trying to save a buck at Murphy, filled up my last Benz on premium, and it was sputtering before I got out of the parking lot. That was enough to dissuade me from returning.

Newkleus Tomorrow marks two weeks that the CEL has been off.

Newkleus I have never left my key in the on position while refilling, I do however quickly turn it to accessory to record the mileage on my tripometer, and then quickly shut it off.

I think it wasnt a coincidence. To the OP.... if i remember correctly, if you refill your tank with the key on the ON position it will take a while for your fuel gauge to read correctly. I am not sure if the Focus is like this, but I know my 05 Malibu was like this, as was my 2000 focus and my 03 F150. id say if you have no trouble with it again you are ok... if you want, try to recreate it by refueling while leaving hte key in the ON position and see if it happens again.

Newkleus Bought fuel at Costco again this weekend because it was so much cheaper that every where else.

amc49 I really can't imagine why they would say it only includes expensive cars. I'd be pushing that as in 'tell me more, do you think I'm an idiot?' Push for a reason, if they can make the statement truthfully they will know why, or they are simply lying to you.

I'd be trying to pull some of that fuel and checking for water content if you run legally mandated ethanol in the fuel. Wouldn't the first time ethanol got left in the open and water condensed in it to make plenty of misery.

Or maybe the fuel got out of whack as to solvent content or similar.

Getting a letter and the fuel system screwing up are too coincidental to me. But then I've watched here in Texas while occasionally they mismix fuel and the blame goes everywhere with finger pointing galore. Last time it was Walmart fuel, Walmart was so quick to distance itself from its' supplier it was breathtaking. Talk about throwing someone under the bus.

I'd be asking them if the car knows whether or not it's a Mercedes before it rolls over and dies............................LOL. (not at you of course)

I'd also give THEM a present, no more fuel purchases at Costco. Fuel savings are useless if they are damaging your car.

whynotthinkwhynot I did it once, but it came back slowly. I don't know what caused it other than I had the key on when I was filling up because I was installing a tune.

Newkleus Anyone have any advice with this issue?

According to the DTC Codes:

P0460 - Fuel Level Sensor Circuit Malfunction The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified fuel fill percentage in the fuel tank. Empty fuel tank
Fuel pump (FP) module stuck open
Incorrectly installed fuel gauge
Damaged instrument cluster
CASE GND circuit open
FLI shorted to VPWR
Damaged PCM
Overfilled fuel tank
Fuel pump (FP) module stuck closed
Damaged fuel gauge
FLI circuit open
FLI circuit shorted to CASE GND or PWR GND
CSE GND shorted to VPWR
Monitor FLI PID and FLI V PID in key ON engine RUNNING. FLI PID at 25% fill (with non matching fuel gauge) and FLI V PID less than 0.90 volts [for FLI PID at 75% fill (with non matching fuel gauge) and FLI V PID greater than 2.45 volts] indicates a hard fault.

Maybe some one that has seen this code before can chime in to narrow it down.

Good luck
