We just bought a 2007 ML350. This was bought “as is”, and previous owner’s had taken good care of it with maintenance. We’ve only owned it for a week, and yesterday the check engine light came on. The first code is for the intake turbine speed sensor, and the second is for intake manifold runner control circuit. Can both these codes be due to the sensor? Or are they in fact two separate issues? Also I seem to be having a hard time finding out exactly where the sensor is located. Trying to see if this is a simple fix that I can handle, or something I would need an actual mechanic to take care of. Any help is appreciated
