Got this error code and the solution from the Mitsubishi dealer was to reprogram my car to lower the sensor sensitivity. Therefore, they did not tried to find the cause of the problem, but disabled the check engine warning by somehow disabling the sensor.
My car is a Lancer GT 2012, 26K km only.
They told me this was a know problem and as per Mitsibushi instructions, but I found no public technical note about that sensor problem.
Any opinion or similar experience ?
