Hi

 

I recently had a hole welded up on my 2005 LS430. The hole was in the Y connector near the gearbox.

I am now getting the VSC light coming on after a short distance.

OBD reader says Catalyst system efficiency below threshold bank 1.

Which side is bank 1, is it the drivers side?

Any ideas?

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
