What codes were present before changing the sensors? WHY did you change the DOWNSTREAM sensors? Do you have a scanner that reads LIVE data , or are you just using a 'code reader'? Need some info to help!

Our VIDA showed lambda incorrect signal, after more intense checking, found temp sensor, and accelerator pedal to have 12v instead of the 5v in diagram. Also fuel tank pressure is out of range even with fuel cap off.
