2000 Nisan Quest , catalytic sensor shows bad at smog test , check engine light went on for a week , added cleaner and went off ... Fresh tank of gas run through ... sensor still showing bad ,,,

I just looked up a sensor for catalytic converter and all I am finding is a Oxygen Sensor ...for 2000 Nissan Quest GXE... Price varies from $18 to over $100 for part ... Don I need a repair manual too ..

Thanx Jim ... I have not failed Smog Test Yet ... The guy I use checked the car with a Hand Held OD2 and the Catalytic Sensor was not reset I guess ... The Check Eng Lite had gone out after a few days of Injector Cleaner , then I added the Garunty to Pass smog cleaner ... then I filled a new tank of gas and ran it ... We just checked it today and that sensor still has not reset ... No light is on ...I have a full tank of gas ... My Plates are good till October so I will go slow on this ... I guess it is called an Oxygen Sensor ? Big Price Difference ...for it . Don

Thanx Again Jim , I will wait till tank drops to 1/4 tank ... Then have My smog test guy check it with his hand held OD2 tester .... I will ask him if he can get it out of computer ... He is a rest only station ... No work on cars . In the old days I did all my own work , even built a engine . I miss the Old Days . Don
