Mark :

Hello, my name is Mark and I will try help you with this.

Mark :

P0606 is a fault inside the ecu with the main processor.

Mark :

The first thing you need to check is that it is getting a good voltage supply to the ecu and also has a good earth connection.

Mark :

If these are ok, the next step would be to have the ecu reflashed with the latest software to see if that helps.

Mark :

If it doesn't then you will need a new ecu.

Mark :

The P0098 code could also be caused by the faulty ecu processor. I would therefore ignore it for the moment and try resolve the major fault code.

Mark :

Once that is cured and the P0098 code is still present, then you can check the sensor and the wiring plug to it.
