Hello guys,
I have a strange problem with my Punto EVO 2010 1.2 48kW LPG instaled. When I start car in colder weather only (bellow 5 degrees celsius), everything goes normal at first. Then after short ride (up to 5 km), when engine is warming up, I get the check engine light with code P1220 TPS sensor implausabile. At first car does not respond to throttle pedal at all, RMP stays at idle no matter what. Then after 5-10 seconds car goes in limp mode, hardly getting over 70 km/h. After few minutes later cars goes off the limp mode and rides normally with check engine light. And after some time of riding, check engine light turns off.
This whole behaviour is happening only when engine is warming up, roughly said every second ride. On 1000 km trip two weeks ago car went without any trouble once it was warmed up. Issue shows up no matter of using LPG or Petrol
I cleaned throttle body during summer because it was oily from camshaft cover vent (fixed with oil catch tank), so I guess that this is not a problem. I also checked connector. But I guess that if some of these were faulty, error would be obvious also when engine is cold or warm, not only when warming up.
I was suspecting battery that is has too low voltage after start (13.9V) so I tested in the shop an bought a new one(still 13.9V after start). But issue is still there. Please, do you guys have any ideas what this should be?
