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: Will this sensor work for a 2005 chevrolet silverado 5.3 1500?Eric R. / Jan 03, 2025
Hi Eric, I'm glad to assist you. No, it is incompatible. Do you need the upstream or downstream sensor? Still, it is best to call our parts specialist (for real-time, live, and immediate assistance) on our toll-free number, 1-866-529-0412 (Monday through Sunday).
