P0120 Falut Code HELP!

My W208 CLK320 was in LIMP mode one day when starting up the engine.
No matter how hard to step on the fuel pedal, the rev only run up to around 2000rpm and the car only can drive at around 10km/h.

ESP Visit Workshop comes up on dashboard too.

I have a check with OBDII and P0120 ( Throttle/Pedal position sensor/ Switch A circuit ) Fault code.

I have tried to clean all the harness connecting th Pedal position sensor and the throttle Body. Even I have replaced a new Pedal Position Sensor with cost me around $100. The situation remains the same. ( I have cleaned the harness connecting to the sensors and the Throttle Body too)

I am wondering what should I replace next? The Throttle Body? or something else I missed?

Thanks for reply.

Problem solved since I have replaced a new Bosch Throttle Body. I think the old one ruined.
