Frequently Asked Questions
Q: Why does my Check Engine Light stay on after installing on a 2013-2018 Altima 2.5L?
A: Ensure your vehicle has California Emissions and is a Sedan. Installing a California-spec sensor on a Federal Emissions car will trigger signal mismatch codes.
Q: How many sensors do I need for my V6 or V8 vehicle?
A: Infiniti G25 (2.5L V6) and Nissan NV2500/NV3500 (5.6L V8) use this identical sensor for both Upstream Right (Bank 1 Sensor 1) and Upstream Left (Bank 2 Sensor 1). If replacing both sides, please order a quantity of 2.
