Failed emissions test...need help
 

OK so the wonderful state of Indiana decided my Blazer needed testing....I failed and got a diagnostic code of P0141......(Bank 1 Sensor 2) can anyone tell me which one to buy...Auto Zone here was absolutely clueless.......thanks

If you create a signature with your vehicle information in it, we would not have to ask...What year is it? :confused:

oh sorry...2001

To my knowledge, there is only one part number for the O2 sensor for your year. I highly recommend getting AC/Delco (part# AFS105), not Bosch or Denso.

thanks ...who carries AC Delco...just dealers I think....

Use this website to locate a parts store near you or this one to order from GM.

http://www.acdelco.com/index.jsp type in your zip in the parts store, not the service center.

I just found amazon.com has them in stock for $55 shipped also.

Thanks to everyone for their help......
