O2 sensor help wanted pls

are the two O2 sensors in the exhaust the same part, or two different parts? does anyone have the two part numbers available? that would be a big help 'cause i'm not finding them...

thanks,

 

sure. it looks to me like 254-9002 is the A/F O2 SENSOR, THE ONE CLOSEST TO THE ENGINE, and 254-4162 is the O2 sensor aft of the cat . that's how it appears to be.

 

Call your dealer. There were changes to them over the years. The dealer will take your VIN and be able to give you the exact part numbers.

 

I went to the DENSO site, put in my truck info, got the part numbers for upstream and downstream, and ordered them through Amazon. Installed without issue, cleaned MAFS, and now my truck runs great and the CEL cleared.
