Unfortunately, ran out of gas today (remaining miles must be wrong, said I have 5) Now getting check engine light i.e. engine status control warning. Have tried to start it a number of times wont disappear. Car ran poorly on the ride home next step?? unhook the battery for a reset, dealer??
Running out of gas can damage the fuel pump. This could be the cause of the problem. First though, see if letting the car sit for a while and then doing a restart, or several restarts, will correct the issue. If not, then take the car to your dealer. I would not disconnect the battery, as the fault code(s) will be lost, likely making diagnosis more difficult.
Why would you trust the remaining miles on a car ECU enough to go down to 5 miles left? Those things aren't super accurate even on cars with less variance in gas consumption.
First off, I agree, the "range remaining" calculation is a mild guess.....I rarely trust it but realize you can get yourself in a bad spot The current gen Fcars ECU's and software are set up to protect the engine.....so if/when the fuel runs low, if fuel pressure drops below a certain pressure (low pressure pump) you should get a warning and the engine will downgrade performance; when the pressure in the high pressure system drops, it literally kills the engine. You always run the risk of frying the low pressure fuel pumps if you run a tank dry, even if the car should theoretically protect you. These pumps are internal tank pumps, and use the fuel itself to cool themselves. The car "running poorly" could be Limp Mode (which, when cleared, will restore the car); it could also be Limp Mode and a problematic fuel pressure situation. Best/quickest/safest thing (after you fill the tank of course) would be to have a dealer plug the DEIS in and check the fuel pressures (they are easily read on the DEIS tool). You'll know if your pumps are affected. You CAN try a hard reset (battery disconnect) but it probably won't clear the code. Check Engine lights typically/can also indicate an emissions error....which could mean everything from a venting issue in the tank to something else, in Ferrari's they are sort of a "Master Caution Light" as most (but not all) potential faults have a unique alert. Please keep us posted
go to walmart and get a $10 scan tool. plug it into the obd2 port under the steering wheel. it'll give you a code that you can look up on google.
Let the car sit overnight. Still getting the check engine Will pick up the Obd 2 today and post the results. Going to wait till I see what you guys think before disconnecting the battery
Entropy the car is definitely in limp mode It did not get much warning before the car shut itself down. Perhaps 10 seconds. Pulled over immediately Tank is full btw
Here are the codes P0087 fuel rail pressure system too low, ? Clogged fuel filter P1556 which is limp mode P1475 could not find Next step. Dealer?? Or try hard reset?? FYI car is due for its yearly may be best to just bring it in. I suspect it will need to be towed
Take her to the dealer and have them sort everything out. Subsequently, try not to drive her without fuel is the gas tank. very best
Frank, call the dealer and have them send over a flatbed for your car. Good time to get everything done with the yearly service. I wouldn't disconnect the battery.
Do not disconnect the battery. You will erase all of the information that a technician needs to properly diagnose the fault with your car. Have someone (the dealership) with a proper diagnostic computer (the Deis) download the fault codes and the parameters in order to determine what is wrong.
Good news on the check engine. Dealer cleared the code and the car runs great. Had its service, picking up on Friday Bad news, drivers side window motor bad, $1450. Hear that is a common problem. Thanks for all your help
Congratulations! (but sorry to hear about the window). I agree with Motob about not disconnecting the battery. That having been said, if you have to get going you could compromise by hooking up your OBDII tool, writing down all the codes and the Freeze Frame data for the technician, then clearing the code with the ODBII tool.
