Frequently Asked Questions Q: What is the difference between an A/F ratio sensor and an O2 sensor? A: Air/Fuel Ratio Sensors (Wide-Band) provide precise, real-time measurements to the ECU, optimizing fuel efficiency and engine output much better than standard narrow-band O2 sensors. Q: Does this fit both Left and Right Upstream positions? A: Yes, for most listed V6 and V8 models, DENSO 234-5060 serves as both Upstream Left (Bank 1 Sensor 1) and Upstream Right (Bank 2 Sensor 1).
