Good morning, I have this 2011 yeti 1.9 CFH 81kw engine in the workshop, the problem that occurs is the engine fault light switching on, but it does not have

no fault in engine operation. In the diagnosis there is the error P0121 00 "error throttle valve implausible signal". The first intervention was cleaning the valve and self-learning but the defect was not solved, so I replaced the throttle valve and the problem was solved. I tried resetting and self-learning but after a week again the same error.

Thank you for your attention.

Roberto.
