hello, i have an engine check light and when i did the OBD check, it came out 0154 which is H02S Circuit Insufficient Activity Bank 2 Sensor 1 , does anyone know what should I do with this problem? thanks

yes u need to replace that ho2s bank 2 sensor 1, they have alot of problems with that, it will fix it

thanks, but how do I do it? is that a circuit cable or something that I can find in any autozone? thanks again

u just have to replace that o2 sensor u can get it at auto zone but my preference is an isuzu part, and just for reference that would be the driver side o2 sensor closest to the exhaust manifold
