Hi,Alan,
Have seen this on a few 03 Avensis 1.6.Emissions check perfect,both sensors switching exactly the same.
Logging P0420 code after a few hundred miles,was told by Toyota Tech only cure was a new ECU,No update available to solve this issue.
I know this is a different vehicle but would it be possible its the same problem.
Regards Christy
