I did look at 1 video with a similar drive train as my truck (Nissan vs Infinity) and following his instructions, I was able to change out both O2 sensors on my truck. The driver side was the hardest but I got through it. The passenger side was a lot easier and took half the time to change them out.If you are a DIY and looking to change out your O2 sensors because you got that pesky engine light on your dashboard and your plug in sensor gives you that PF something code, get the DENSO line of O2 sensors. ### ⭐⭐⭐⭐⭐ Right fit *by F***. on January 2, 2024* Exelent price --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/97988019-denso-air-fuel-ratio-sensor-234-9148-fits-select-models](https://www.desertcart.tn/products/97988019-denso-air-fuel-ratio-sensor-234-9148-fits-select-models) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
