HELP! Check engine light won't go off after running out of gas

So this is what I get for letting the gf drive my car....

As it was running out of gas she said the check engine light started to flash. After I came and filled the car up the light still wouldt go off. I'm assuming the misfires as it ran out of gas caused it to come on.

My question is; after a few cycles will the system reset itself- allowing the CEL to go off automatically? Or do I have to go to the dealer to reset the system? I'm assuming there's no way I can reset the system myself either?

If you had an OBDII scanner, you could easily reset the CEL. At this point, you could disconnect the battery at the switch or, just drive it for up to 50 miles to recycle it.

Try turning the ignition on and off several times to help clear the code. As a last resort you can turn off the battery in the trunk to "clear" the code and see if it comes back.

These are simply steps that may get the light to turn off. If you have a real problem, the solution will be to get a code reader and find out what the issue is!

If you don't own an OBD2 reader, go buy one. It may be the best $60 you spend on your car.

Codes P1145 & P0441

Can anyone tell me what codes P1145 and P0441 mean?

CEL came on today after run of about 60 miles, with about 50 miles at highway speed. Gas about 1/4, last filled up about 3 weeks ago. Temperature in high 60's low 70s. OBD showed P1145.

A few weeks ago CEL resulted in P0441 after similar driving as above. Cleared code.

In both cases car ran fine before and after CEL.

Advice? Thanks in advance!

For both codes?

I always give the gas cap "an extra turn" and thought it was tight, but maybe not. Filled car today. CEL still on. I could clear it with my OBDII analyzer but thought I might see if it clears itself with a few ignition starts and maybe a battery turn off / on. Car seems to be running fine.

Thanks

I continued to have some CEL issues. The codes had been deleted through the use of an OBDII analyzer (which doesn't have the Maserati specific codes) and a battery turn-off, so I could only give the dealer the code numbers from the OBDII. They couldn't find the source of the problem They suggested I get the car to them as soon as posisble after the CEL came on the next time, which I did. They retrieved P1180, a different code than the OBDII had retreived earlier. This could be completely unrelated to the earlier codes or possiibly the OBDII readings were wrong, I simply don't know. However as a result of the dealer's scan, they replaced the "air flow meter", part 180045. The change is amazing to me. The throttle response and smoothness are substantially improved (previoiusly some stumble and needed to put my foot into it).

The moral of the story, for me, is that sometimes the CEL is meaningless or insignificant (even the dealer commented that CEL could be related to gas cap) but sometimes there is something more and you might need the assistance of the shop.

Sounds like a good reason for owners to have an OBD2 reader with Maserati specific codes installed.

Agreed! And good advice to anyone thinking of buying an OBDII analyzer.

Frankly, although the generic OBDII analyzer can be used to read a code to determine whether it's a recurring code and deleting the codes, it seems that there might be little real value in having an analyzer without Maserati specific codes.

Post CEL and P0102 MAF problem

I got the Po102 code using my own scanner. Turned it off but came back. I did this several times but got the same result. It came as a MAF/volume air flow problem. Put fresh densos and then went to dealer on mass with 10 people from Uk sportsmaserati forum courtesy of a nice young lady called Andrea. She arranged the meet and greet at the largest FM dealer in Europe. They looked after us well and provided refreshments and access to the workshop. they hooked it up to the SD2 and cleared code but it came back with the CEL light. BTW the car drives with normal agressive behaviour (i am lucky to have the old CC software).

Some suggested cleaning the MAF or replacing the MAF, followed by a check on injectors and the oxygen sensors but my car drives normal and have 100% wear on clutch so it could be the clutch causing the CEL.

The dealers also checked my CC fluid and all for free. I happily gave £10 each to the 2 techs as a measure of my gratitude (Maseratis are driven by gentlemen).

Any thoughts /advice?

cheers

007, sorry I can't help. My car is a GT. That said, with the change in throttle response, shifts with stick and clutch pedal are smoother, I assume because of better modulation in throttle.

Maserati engine lights.......seemingly off and on endlessly

anyone else experience the dreaded Maz Engine Status Control System light which seems to have some sort of " ghost life" of it's own and goes on and off with the regularity if changed underwear. ( this maybe a day for some, a month for others).....I'm told it is usually an O2 problem with fuel mixture. Can anyone shine some light on this heading for my friends Car. I've never had this problem and my car runs like new, which pisses him off to no end

Hi

The engine light won't come on unless theres a problem. You can find out what it is with a cheap code reader from ebay (less than $20)

Most likely cause is a misfire or lambda sensor failure, particularly if it's resetting itself. In any event it should probably be looked at. Either condition can put fuel into your cats, and that can get expensive. It might also be the cats breaking up, and that can get very very expensive.
