Hi all is my Alphard 3.0 V6 2005 a OBD II compliant vehicle. 

Thank you Guys sensor under car replaced all ok.  

Can anyone send me a diagram of the location of the Oxygen sensors on my Toyota Alphard 3.0 V6

Model TA-MNH10W-PRASK-E 

Engine 1MZ-FE

There is supposed to be 4 sensors I can only find 2 in any of the documents or you tube videos.

Many Thanks.

Thank you - are the 2 sensors the same?
