I got my Rio yesterday from the dealer (another time). They put a new ground wire in the Lambda tester and make a reset, but inmediately, the engine check light ... ON again, just in the door. I ask for the error code and they said that is 0340, but they aren´t sure of the cause. <_<
Tomorrow I must take the car again, they are going to change the gas measurer, to see if with that the light is extinguished.
They say to me that it completes possibility is that there is badly a contact, and the solution is to change all the electric installation.
Somebody knows about that light?
Thanks
