Technical Fiat Bravo 2 Multiair has P1512 P1120 faults

[DmytroT]

Hi, guys! My Bravo a little bit nervous)
During the movement sometimes it doesn’t react on acceleration, but engine is still working.
Then I have on my plate the next errors: hill holder, ESP, ASR, and check engine. Usually, I switch off the ignition and after 1 or 2 minutes I start the engine without any problems. All faults disappear and only check engine still flashing.
Computer diagnostics showed that I have next faults P1512, P1120, O0422.
Who did have such problems?

The problem was solved by cleaning a drossel including its electrical part

I cleaned the throttle. But I didn't just clean the throttle, I also cleaned the elements under the cover where the electric motor is located. You have to be very gentle and careful.
