There is a Tsb about the issues . Change the Crank Shaft Sensor & The cam Shaft Sensors it should run after that

You need to change those sensors and clear codes ,when the engine runs then scan again, the other codes are collateral faults caused by the P2034 code,

so you clear first and you deal with any other codes if any , caused they might clear up after the second scan and hopefully with car running after the sensors replacement

1-Fault code P203B

2- P2006( look at the diagram )

3-P203B

4- P2034
