do you replace all sensors (oxygen when codes are for all sensors

Hello, assuming with OBDII this is really: P1152 P1132 P0135 P0141 P0155 P0161 Recommend to clear codes and see what comes back. It is likely that some of these codes are as a result of the real problem, and probably does not indicate the need to replace both pre-cat sensors and post cat sensors. Furthermore, since it's both bank one and bank two, suspect some kind of fuel control issue more than the sensors themselves. It's highly unusual to imagine all 4 sensors failing at once.

NO .. You do not replace any parts just because there are codes present .. Best to use that money on a professional diagnosis and save a few buck at the same time! - SERIOUSLY ▪️https://repairpal.com/repair-shops▪️
