I have a 98mitsubishi montero my check ingine light is on i hooked up my computer to read the code it reads bank 1/2 P0161oxygen sensor which oxygen sensor is the one on the driver side or passenger side


Bank 1 is on the side that cylinder number 1 is on, and 2 is on the other . Look up your firing order and you should find it fairly easily. And sensor 1&2 refers to before or behind catylitic converter.

Error code P0430 rear catlytic converter where exactly is this located and what does it look like and estimated price?


just a word of advice there is no sensor that tells you if you need a cat ! that code comes on because of faulty o2 sensors have you changed the 02 sensors yet ? if not change them reset ( clear ) the codes that code will come on a few times just keep resetting or clearing it i have had 2 co workers not listen to me and changed the cat 400-600 dollars and the code just comes back on one guy had the cat changed two times and the code came back after i reset the codes 3 times it stayed off it seems like its preset to come on around 100,000 miles with 02 sensor codes DONT LET THE MECHANIC SELL YOU A CAT hope this helps

Senor oxgen 2nd bank downstream Where are they located


you have 4 o2 sensors and 4 catylitic converters. bank 1 sensors are located on the passenger side exhaust. #1 is before the catylitic converters and #2 is after. bank two, on the drivers side, has the same configuration, the downstream sensor is after the cats.

I have an 99 Chevy Silverado Truck 5.3 liter engine, and the ODB code is PO420 can you help me pinpoint the reasons?


the code you show is for the oxygen sensors post convertor. replace both the o2 sensors after the convertor and the code will go away on its own after a couple normal condition drive cycles
