The MIL light up and I got the P0501 Code. (Speed Sensor)
I use a ScangagueII and the Speed is 0 KM/H at any speed. (was working before)
But the in dash Speed meter work no problem.
I look on the HMAservice web page and did not found were is located the Speed Sensor.
I do not know if it is related but I change my tire for my summer tire before the MIL light up...
