2004 Mitsubishi Colt 1.1 Engine management light & code P0122

This fault began after a local garaged serviced the car, they of course deny any responsibility!

Engine management light comes on and car enters 'limp home mode'.

If turned off and left for a bit, car drives normally again with light still on. Light then goes off after a while. The car will then drive perfectly for around a week until the fault occurs again.

I have pulled several codes from the ecu but mainly P0122.

Any clues or pointers greatly appreciated!

    Thanks for your thoughts.

    I have checked continuity on the TPS connector and then replaced the Throttle pedal assy.

    The car ran perfectly for a week and then failed again today with the code P0122

    Also showing code P1961 which I don't know the meaning of.

    Any more suggestions gratefully received.

    Thanks, Kev

    Aha, No, I was looking at the sensor and connector on the throttle pedal itself.

    Will have a look at the throttle valve in the light tomorrow and let you know!

    Many thanks for pointing me in the right direction.

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.

P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
This sounds like either the TPS is unplugged or defective, if the connector is clean and tight then replace the TPS

    The TPS is on the throttle valve, you understand this correct?

Got mitsubishi colt cz3 1.5 07reg wot kind of job is it to pnt a clutch in

Did Mitsubishi find the clutch fault at any of the service intervals on the the car in the first 3 years of ownership - if so why not take the matter to court,have it removed send it to them via a dealership ask their opinion why it has prematurely failed - chances are it was not adjusted properly in the first place,a breakage,a production problem. They will deny it is their problem and blame driver error,you take the matter to a small claims court to recover the repair. Read Mitsubishi clutch failure cover up on the web - it will give you a good idea about the nature of Mitsubishi.

My 2006 mitsubishi colt check engine light comes on and the accelerator pedal is giving no power and the car limps when this happens, then the car goes fine again?

There are many emission sensors in the car that will make the engine light come ON. Not to mention the big list of trouble codes for the engine light. The engine light code will give you a big clue of what's causing the accelerator pedal problem.

Best way to find out what's going on engine light is to have an auto-parts store hook up a engine code reader and tell you what the code means and the problem. Most auto-part store will do this for free.
