1.2 limp mode urgent help please!

[JackJack]

My 1.2 has just started going into limp mode today and is becoming more frequent.

Mate has read the codes and it came up with something to do with the throttle pedal.

What exactly needs doing and how much is this going to cost?

Thanks in advance need this sorted asap.

It depends on the code(s) found but its a "how long is a piece of string" question. It could simply need a new pedal potentiometer or a throttle body but as its a 1.2 16v it could also be a wiring issue... theyre known for them.

Oh right the ecu box has been removed so its not that rubbing on the wires if thats any help.

Im pretty sure the code was something to do with the pedal and not the throttle body.

ive done afew of these lately at work, ive found its the loom plug to the ecu(with nasty metal cover) i think its the left hand one. when you remove it from the ecu the glue inside the plug seems to melt and you get a bad connection. when you remove the plug look at the ecu pins. if there covered in glue/silicon deposits that could be the prob. seems to be very common when it come up with a pedal/ throttle body track1/2 code. we just change the engine loom which costs about £175 but you mite be able to clean it up. they are fussy with spark plugs and the gap, coil pack etc etc i could go on! try the ecu plug tho!

Could a faulty lambda sensor cause it to go into limp mode?

Got the exact same problem as my car, mechanics cleaned the throttle body, checked sensors etc
Now he reckons its the ECU - £200

:s

 

[JackJack]

Had the accelerator pedal off and cleaned it is sorted (for now anyway)

Started again today

Im going to order a new pedal and see if that fixes it for longer than 2 weeks.
