This is about a 2002 Nissan Pathfinder LE with ~57,000 miles.  
It has a bad O2 sensor, i can change the O2 sensor myself but, the ECM needs to be reflashed after the O2 is changed (stupid nissan…).

I went to autozone, and it threw these codes

- P1167 (Heated O2 Sensor 2) ???
- P0159 (Rear O2S, Bank 2) Response time too high…
- P0158 (Rear O2S, Bank 2) Voltage is too high…

I could go to the stealership, but i don’t want to get ripped off.  
They charge $80 to tell me the same thing Autozone told me. I can’t justify spending $80 for something thats going to take 2 minutes to do. The reprogramming would be extra!! $200 or so.

There is a TSB out on this

Apparently warranty doesnt cover this.

Can anyone reprogram the ECM for me?  
What else can i do?

Thanks

U dont need to reprogram anything…all u need to do is turn a screw on the ECU…to reset it…reset does not = reprogramming…or anyone with an obdII scanner can reset and clear the codes

that too…the ECU will eventually clear itself after it completes a cycle
