Code should be for fuel level lost message - does the gas guage or mileage to empty change when this happens

U110C lost fuel level message. is this something to do with the pcm


Hi Anonymous, Im glad to help!

The U110C is a BUS Message and usually has to do with both PCM and BCM, because its a lose of BUS Signal between the PCM and the BCM.

FIRST THING TO TRY:
The first thing I would try is remove the negative battery cable for 20 seconds then replace it. NEXT: Start the engine several times then let idle for 10 to 20 minutes then start it several more times and if the code doesn't return and the check engine light stays out, simple drive it for awhile like you normally would. If the code come right back, below is some common problems.

COMMON CAUSES of U110C:
(1) Communication with BCM is lost / See if you can communicate with the BCM.
(2) PCI Bus Circuit open between PCM and BCM / Check the positive and negative bus signal at both the PCM and BCM.
(3) BCM
(4) PCM
(5) Fuel Level Bus Message is missing

Obviously, all these issues must be tested to see which one is causing the problem. BUT first try the battery cable removal and see what happens.

Let me know the out come and I'll try to help further.
Hope this helps and have an awesome day!

Check engine Light (emission Control System)


wait about a day and let the car dry out some. Then reset the check engine light by unhooking the negative cable from the battery for 15 minutes or more. Hook it back up and see if the cel even comes back on. It probably wont but if it does, go to parts store and get the code and go from there. Shouldnt be a big deal, car is prob ok. Just get code if it does happen to come back on and reveal the year, make and model of the car and the code. But you need to reset the light 1st to see if it comes back on.

Had my check engine light checked at a autozone and came up with a u110c... Any ideas for this code?


Code u110c ( no fuel level) Remove the gas cap from the van. Reinstall and make sure to give the gas cap a full 5 to 6 turns. The code set in the system was set by the gas cap not being tightened enough or a faulty fuel cap. If it continues to reset code then replace fuel cap on van. Hope this will help.

Dodge Gr Caravan error codes U0155, U110C, U0140


you are incorrect on your code read. u0155 is lost comm with IPC, u110c is no fuel read, u0140 lost comm with BCM and can all be fixed with a new BCM.

Engine management light intermittently comes on after rain or carwash. Light goes off after a day or two 'drying out'. No obvious running problems but I'm concerned that it may try to warn me of something...


The only thing that comes to mind is the fuel cap. The management system is designed to flash a warning for 2 key cylcles and then remain constant to warn driver if the gas cap is loose, P0440 will then be stored in the hard drive(major leak in evap. system) Are you having fuel put in the vehicle at the time the light is coming on? You should have the vehicle scanned for codes at an authorized repair shop.

Check the cap and rotor for internal carbon tracking or, just change them. Also, take a look at the coil when its dark and rainy and see if there is any arcing where the coil wire goes into it.

The rain is the culprit. It studders, misses, dies. Won't start.


Check the distributor cap and rotor. A usual culprit in wet weather. The CHECK ENGINE light is most likely a side effect. Have codes checked to be sure. Hope this helps

1992 accord hard starts,engine light, steam off hood in rain


The check engine light comes ON when the cars computer(the ECU) notices any kind of electrical problem in car.In some cases the check engine light comes on then turns off.In that case the exact error is not getting confirmed so this happens.But once the problem gets confirmed the engine light will remain permanently ON till the problem gets solved.In this case i suggest you to get your car scanned at autozone service center.Its absolutely free.In case in the car scanning,if any error code is retrieved then you can check which part is faulty as per the error code.In case if no error code is retrieved then you can continue driving,till you get any confirmed indication. ---------- This will help.Thanks.Helpmech.
