2005 focus 1.6 limp mode problem and P2100 code

Vehicle keeps jumping into limp mode, it started months ago now, the revs would bounce at about 1100rpm and max at 2500rpm and the fault code P2100 was present. It would give me more miles between the fault when i filled up fuel. i was told to replace throttle body valve which i did (with second hand one) and it done the same. After weeks of the same problem it stopped. But it has now stated again... same limp mode and same fault code (P2100). i have spoke to people at a ford garage and other mechanics with no suggestions so far. Could it be fuel system fault, inlet manifold/throttle fault or something else...

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!!

    Yeah I have cleared the code several times now. I am trying to get my hands on a second throttle body now but it\'s a bit hard on the bank holiday...

Mechanics advised that gearbox needs replace after diagnostic Of codes . Dash light still on after codes being read , have had ecu replaced 2yrs ago ? What do you think it could be , thanks phil


didnt specify vehicle --generic answer--until repair is made the vehicle will show engine light and have codes --if gearbox is problem for limp mode /until repairs are made or gearbox replaced you will be in limp mode --and as to sensor find out what one it was --start problem may show back up if sensor was problem --and GET a 3rd opinion you have 2 mechanics with different opinions on your problem and i guess they are reading your trouble codes differently

Kia sportage diesel acceleration problem


Do you have any check engine lights on? Most diesels have a safety feature that shuts down the engine and puts it in "limp mode" when there is a problem somewhere . It will stay in limp mode till repaired and the code cleared. You should get a code with a diagnostic.

How do I fix my 2004Ford Focus going into limp mode doesnt do it all the time bad after stop and pulling out into traffic . engine light doesn't came on (?)


TEDDY is right on Point. First if this is happening, YOU should not be driving it. YOU are a danger to yourself and those around you and I am sure you do not want to cause an accident or be in an accident.... with that said... I am 95% sure your issue is Transmission Related although Teddy is correct with the other issues that could cause it.

Limp Mode is designed to "GET YOU OFF THE ROAD SAFELY" (you know... Limp Home).... Now that you are home, you need to discover the issue and the vast majority of the time with the Focus is the Transmission Codes. Many of these "MAY" set a CEL but not always, once you start to Scan the vehicle with a Diagnostic Scanner, the issue may be plain to see. Majority of time it has to do with the TCC Solenoid (Torque Converter Clutch)... It could also be something as simple as a Clogged Fuel Filter, MAF Sensor, Clogged Converter are some issues that can cause it.

Scan the Car and you will get some more information.. Something like a P0191....

Let us know what you find out..

Sounds like your vehicle is in limp mode. Check for faults with a fault code scanner at a local auto parts store. Resetting the fault will fix the limp mode, but not whatever caused your vehicle to initiate limp mode.

1 month ago my x type went into limp mode. Mechanic had it for three days and could find nothing wrong. Then today it went into limp mode four times. No warning lights on dash


The only time a vehicle goes into limp mode is when there is ****** problems, so I would take it to the ****** shop for code retrivel and if I am not wrong there might be problem with the Input/Output speed sensors BUT do have it checked first.

Well the tcm is going into limp in mode. Have the vehicle scanned. If it is in limp then it has a trouble code in the tcm. This will give you a clue to what is going on.
