Bought this for my 1997 GMC Sierra c1500, with a PO141 code. It came with anti-seize in a separate tube which I loved, and shipped to me in 2 days. I’ll definitely order this part if my bank 2 sensor ever goes out. Worked great!

Question: I have a 1995 Chevy G20 350cid conversion van, I see only one O2 sensor and its upstream of the cat, The one Im replacing has 3 wires, yet almost all I see that's listed for this vehicle has only one wire. First question- is this the one I need? Second Question-Is the single wire one the new updated version and if yes which of the 3 pins on the vehicle do I connect it to?John B. / Mar 28, 2022
Hi John, thank you for reaching out. Since you mentioned that your oxygen sensor is a 3-wire type, then yes. The single wire oxygen sensor isn't a new design. It's only applicable to models that use a single wire oxygen sensor. You can use this link to go back to the item page and continue the order: https://www.carparts.com/oxygen-sensor/ac-delco/acafs76?can=CPAP3648_20220328
Enjoy shopping.
