I have just replace the left side 02 sensor as the previuos one seemed to be faulty.

 

Just ran the car on conzult and following result.

 

Both 02 sensor run at around 0.30v on start up then when the idle speed drops back to 900rpm the R/S drops to 0.20v but the L/S keeps dropping away until it reads 0.00v

 

When the engine is reved the L/S shots up to the same reaing as the R/S then drops back to 0!

 

Any ideas as this is what the last one did?

I thought they switched between 0 - 1v ?

Bad connections to it?

 

Sounds like a lazy o2 sensor but it would be odd if its the same after you replaced it
