My question is my 2002 Montero sport takes a while to shift does it mean I need a transmission


If transmission fluid level is up to par then you just might need tranny repair. And that is not cheap.

O2 Sensor defect


MR988905 costs $300+

SNG O2 sensor is just below $100

they may claim being made with the same quality and both are tagged "direct fit" for easy installation.

its just my idea, good luck.

Could the catalytic converter cause this code 2002 mitsubishi montero sport 3.5 p0161 code changed the o2 sensor and still get the same code could the catalytic converter cause this code


No it has nothing to do with the cat.
Code 161 is for a problem with the heater circuit for sensor 2 bank two. Either the heater in the sensor has failed, or the circuit that powers the heater is not working.

you need to change all the o2 sensors reset the computer it might come back on a couple of times just keep resetting it you could buy one of the cheap code scanners for 49 or 59 dollars and reset yourself if you go to a shop they are going to sell you a catalytic converter for a few hundred bucks and the code will come back. let me guess you got about 100,000 miles on it what it really means is a shop or dealer will get paid for a cat job when you dont need one
