Quick question on banks and O2 sensors when it comes to error codes:
P0420 - Catalyst System Efficiency Below Threshold (BANK 1)
P0430 - Catalyst System Efficiency Below Threshold (BANK 2)
P2198 - O2 Sensor Signal Stuck Rich BANK 2 (SENSOR 1)
May I know, where is the system referring to for BANK 1 and BANK 2 ? And Sensor 1 and Sensor 2 ?
I have an image below illustrating the 2 O2 sensors (Green & Blue) on one side of the F430 engine:
Bank 1 refers to the RIGHT side of the engine and Bank 2 refers to the LEFT side of the engine ?
Sensor 1 refers to the PRECAT 02 Sensor (at the headers) and Sensor 2 refers to the POSTCAT 02 Sensor ?
I have an aftermarket high flow cat I know, but shouldnt this only trigger Sensor 2 and not 1, since Sensor 1 means PRECAT (at the headers) ?
