Hello,

Need some help and advice on my car. I scanned my 99 C70 Coupe and the following error codes came up

6b00 Malfunction Indicator Lamp
4801 3-Way Catalytic Converter Bank 1
6806 Turbo Control Valve
510f Vehicle Speed Signal
1300 MAF Sensor


I already fixed the MAF Sensor, but still yet to tackle the first four problems.

any suggestions out there?

Thanks!

Wei.
