Limp Mode (1200 rpm) and no acceleration pedal

Hello everyone. I have a big problem with my Rover 45 2002, 2,0 Diesel. The check engine came on, the engine speed is 1200 rpm constantly, without accelerating and I am not able to use the acceleration. If I stop the engine and turn it on again, sometimes is everything fine, sometimes the problem is still there.



I have replaced the throtle sensor and still the problem there.



I erased with a tester the error codes from engine, and after a few minutes the same problem with limp mode. And the remaining error isȘ



P0121 -Acceleration pedal sensor. implausible signal.

- Test not complete.



Please help me, I can drive only with maximum speed of 50 km/h.
