Ve commodore P0050 and P0030 after timing chain replacement

[Kirkn11]

Hi everyone

My Ve commodore has P0050 and P0030 errir after timing chain replacement. It used to have the usual timing errors . So once fixed it shows these sensor errors now. The P0030 went away on It's own. Just wondering wherethe sensors connect in the engine bay or if someone has any ideas. Thanks

O2 sensors so on the exhaust pipe and follow the wire to the connector, that is the quick easy way.
