The Upstream O2 Sensor designed for various Nissan models, including the Altima and Versa, has generally received mixed reviews from customers. Many users have expressed satisfaction with the product, highlighting its ease of installation and effectiveness in resolving issues such as check engine lights and emissions tests. One customer specifically noted that after replacing their old sensor with this product, their problem was resolved, indicating a positive experience overall. However, the reception has not been completely favorable. Some reviews reflect disappointment, particularly around compatibility issues. One notable user reported that the sensor did not fit their 2017 Nissan Altima SR 2.5L and expressed frustration at the lack of support from Amazon regarding refunds or exchanges. Another review pointed out that while the sensor fit into a 2014 Altima, it did not function optimally as it caused persistent check engine light due to voltage discrepancies, emphasizing that the vehicle's ECU may be overly sensitive and require OEM replacements. In summary, while the Upstream O2 Sensor delivers effective results for many customers, compatibility and performance issues for certain models caution potential buyers. **
