My girlfriends car has just started with the same problem, a limp home from the garage, a sleep over night and als well next day, for a while... I spoke to Mitsubishi and they have told me the TPS (throttle positioning sensor) is on the accelorator pedle assembly. There PN for this is MN125791 and its circa £88 + VAT. After exhausting all other options I may attempt this replacement and will advise the results.

The only thing these components have in common is the ground wires. There are many grounds on a vehicle. But the main three are the battery to body, battery to engine and engine to body. These are fairly large wires/cables. They should be checked with an ohm meter. I replace or repair any wires that have more than 5.0 ohms of resistance.
Known as Limp mode.you have to get a garage to run diagnostics in this scenario.it could be anything from fuel ,electrical exhaust and any fault will be stored in the ECU on board .the engine management light usually flashes when cars go into limp mode.
its the yellow icon on dashboard.one time I had an electronic throttle linkage play up every time it rained and a few hard pumps put the car back out of limp mode.your next move is to get it to a garage who can run on board diagnostics to pinpoint the cause via the error codes that show during the tests.limp mode is to protect further damage to engine but allow you to get it yo a garage or home.
Engine management light can mean just about anything. It comes on when the computer detects a fault in the engine or other vital part. it then adjusts what it can to get you home (limp home mode) you need to take the car to a garage and get them to put it on their diagnostic equipment. Trouble with Engine Management light is that it covers just about every part of the engine so unless you have the equipment and skills required its almost impossible for you to tell what's wrong. It may be a very small thing or something more serious but only someone with a diagnostic machine can tell you
you need to get yoyr car to a local trusted garage and have the diagnostic system scanned. The car is in limp mode because a sensor has either indicated a problem or a part has blocked or failed. The exhaust will glow because the fueling is all upset.
It may well be an airflow sensor, coolant sensor fault which will clog up the upstream lambda and put the engine into limp.
Dont guess...get it scanned...it will be much cheaper.
any time i have that problem where no fault can be found i try a new ecm/pcm almost every thing is run by it. if your using a dealer go to another or see general manager . at our dealer 2nd time in service manager steps in, 3rd time in general, service, parts manager, and all shop to fix car.
The engine has gone into limp mode because of a fault. When this happens the engine managment system shuts down some of the power to prevent damage to the engine and its components. Best bet is to take it to a garage and have them run a diagnostic check to see if any fault codes are showing.
the 'wrench' symbol is a service light or possibly an engine managment symbol. if the car 'kinda' drive of a fashion then its computer has dropped onto 'limp home' mode and ur car needs to be put onto a diagnostic fault finder at a garage.
Code 24 is a vehicle speed signal sensor fault, the sensor most likely does not provide a useable signal until about 25 MPH, when the computer doesn't see any signal after that speed it turns on the light. Make sense?
