If your mechanic is clearing the code he should also be able to diagnose the code he is clearing. Your transmission is in safe mode or limp home. Take it to a shop that knows what they are doing

    It has done it several times now. The computer said it was something not sure what it was but mechanic changed it and it was right for awhile. Then it did it again he put thing on it and it said something else so he cleared computer and it was right again. Then it did it again and it said it didnt read key so he cleared it and i changed the battery and its been ok for a week. Now its done it again and while usually if i leave car off overnight it rights itself. But this time it hasnt i just dont know what to do now. Should i take it to Mecedes mechanic and pay alot of money for them to look at it. I appreciate your comments. Thank You.

    It sounds like your mechanic is guessing at the problem, this will most likely cost you more due to repairs he's completed that have not solved the problem. Everytime the computers memory is erased the vehicle is ok until the drive cycle is completed and the computer recogniZes your car has a problem. Take the car to an independent European repair facility or yes bite the bullet and pay the dealer. You are wasting your time and money with your mechanic now. Clearing a code stored in the ECM does nothgn

    Nothing to solve your problem.

    Many sensors can cause a car to go into limp mode, sounds like your it only starts giving you problems when the car warms up. So when your car in closed loop, you probably have a problems with a primary input sensor such as primary o2s. Coolant temp sensor, maf sensor etc.

SOURCE: 2002 chrysler town and country wont leave limp mode

try getting a new shift solenoid for it. i had the same problem on my 2002 chrysler town and country and my plymouth breeze which is also a dodge product. it is very simple to do and doesnt take all that long. the part will probably run you about 150 to 200 dollars but it should fix your problem.

SOURCE: limp mode on a automatic

Firstly, disconnect the battery and leave it for a few hours. Reconnect and try the car again. This resets the memory in the TCM. If the car picks up the faults again, it will go into limp mode again after a short while. If it's been a while since you changed the fluid, then put some seafoam transtune in to clean all the parts and plates. Then after a few days at least, preferably a week, go for a fluid and filter change. After this, you'll probably find it will go into limp mode again, just disconnect the battery again and reconnect after a few hours. I had the same problem in my chrysler T&C. I left seafoam in it for a week and it cleaned up all of the gum and varnish build up on the shift solenoid pack and plates.

If the problem persists, and after you find it allows you to change gears for a while and then goes into limp mode, it could be gummed up solenoid pack, or input speed sensor.

Go to o'reillys and plug in their diagnostic tool. It should provide you with the fault codes if any. If no codes, then your TCM and ECM are in good shape, and if you're lucky then it'll be something simple like a sensor, or solenoid. Try cleaning it first with seafoam transtune in the fluid for a week.

If all else fails, and their are fault codes, then take the car to a trusted transmission repair shop for a road test. The computer could be picking up slippage and making the car go into limp mode. This could be the clutch plates if no errors with the TCM, ECM are present, and you've ended up checking out the input speed sensor, and solenoid pack. The latter can cause hard shifting and slippage too, if the seed sensor is set to signal when to change gear, but the new oil, or old oil have made the friction slightly different to what it is used to or within factory limits. Firstly try reseting the TCM by disconnecting the battery for a while and see what happens.

Good luck

Hi, have a citroen Ds3 dsport...anti pollution fault, asr/esp, limp mode...need to get out of limp mode to accelerate to clear system... Need help as it's driving me nuts!!!!


the limp mode will not allow you to accelerate until you have fixed the problem and reset the ECM
Limp modes are not there to help ease you frustrations but to prevent costly repairs to the engine and transmission
fix it , reset it then you will have no need to go nuts

Limp mode changed master,slave Drive i know sensors vss tcm egr but i want to know the straight up,how do you get this out of this mode. Sorry


You may not be able to come out of limp mode until the problem the computer is seeing is repaired. The computer determines if something is affecting proper engine/transmission operation and for safety implements LIMP mode to protect other operating systems from possible damage. Do a diagnostic scan and repair the problem

2005 focus 1.6 limp mode problem and P2100 code


Try clearing the code from the computer. If it returns again, the second hand one could be bad also! Some codes are what they call a hard code, that stays in the computer memory, and will think that the problem wasn't repaired (even though the part was replaced). Till the code is cleared from the memory, the vehicle will return to a limp mode untill the problem is resolved!!

On my dash pannel i have a light come on that looks like a round gear with an exclamation point in the center what is this and what does it mean


Car's transmission's gone into limp mode. "Limp Mode", is where your transmission's ECU keeps the trans from killing itself. Have you noticed a difference in acceleration? When you get on the highway are your RPM's higher than normal?

Limp Mode restricts your engine and transmission from working itself too hard to keep it from messing something up. Could keep it from getting to certain gears, keep it from revving too high.

It could be the transmission ECU (its computer). Then again it could be the transmission.
Take it to a mechanic or a friend with a ECU code reader. That will tell you a better idea of what could be wrong.

Good luck friend.

1997Plyouth Grand Carvan will not shift in to gear.Gets up to 35 or 40 mph and will not shift


your van is going into "limp" mode,
when the computer sees a problem from the transmission it will not up shift but will remain in low gear so you can limp to a shop for repairs,
it will also clear the faulty code every time you turn the key off then back on,but if the problem shows up again it will go to limp mode,three things cause your problem,
first is a speed sensor,if your speedometer is working it is not that.
input sensor,or output sensor both are easy fixes,they just screw in to the transmission.

TRANS WILL GO TO LIMP MODE. WILL NOT RESET WITH SEVERAL ATTEMPTS OF TURNING THE IGNITION ON AND OFF. IT WILL RESET AFTER ENGINE IS OFF FOR AN EXTENDED PERIOD OF TIME.


You will need a mechanic to clear the codes with a computer, or disconnect the battery for a while and reconnect it. Make sure all electronics are off, ie stereo, before disconnecting. However if there is a problem with the transmission it will continue to go into limp mode until the problem is fixed.

My volvo 850 transmition cut out on me. For a while the arrow on the dash was blinking and it would switch to limp mode. I brought it in to be looked at and they didn't find a problem. Last time it...


Any time the transmission goes into the limp mode, it generates an error code that tells what caused it to go into limp mode. It could be something as simple as a loose connection on a sensor for the transmission computer. The code would explain which sensor was sending the correct signal.
By restarting the car you are resetting the transmission computer, clearing the limp condition.

Transmission locked up, felt like it was stuck in second or third gear. not shifting. shut engine off and restarted , shifting properly now. what causes this.


It was a temporary fault that put the car into limp mode (a safeguard operating condition designed to protect the transmission in case of serious failure). Sometimes a transient fault can occur, and the car goes into limp mode just to be sure it's not for real. Shutting off and restarting the car is the usual way to clear the fault and return the car to normal operation - if the problem was real, the car would've stayed in limp mode after restart, or gone into limp once you started driving again. I wouldn't sweat this one, since it went right back to normal operation.
