The code description is about as useful as a fart in a thunderstorm and as far as I know relates to a transmission fault. See link below for a library of codes.
Renault software systems are distinctly different to that of most other Europen vehicles and not all diagnostic systems are compatible.

I would suspect a duff engine coolent sensor giving incorrect readings to the ECU whereby it always thinks the engine is hot. There is also the possibilty of a duff TDC sesnor - a fairly common problem related to poor starting.

Honda Civic 1.4l
