(I am watching the wedding but working on my motor at the same time !).
Just wondering if any one can help, my PA Software is reporting that post o2 sensor CAT BANK 2 is failing :
-First error over two months 2727 Lambda Sensor Timing Post Cat Bank 2
-Yesterday Second error 2724 Lambda Sensor Sensor Post Cat Bank 2 Signal
Where is CAT BANK 2 Been searching all over the Net I have 5 sensors 3 of them regulating and 2 Monitors, one of the monitors is on the manifold cat and the other is on the middle pipe after the middle cat.
I'm proper confused, I want to replace it but, want to replace the right one, also I am hoping in replacing this it will solve my intermittent power issues at certian Speed and RPM (I have a manual 5 speed).
The o2 Sensor in question seems to be getting worse as the error 2724 is new, and it seems the power issue is getting worse.
Thanks for anyone who took the time out to read this post.
