[ Frequently Asked Questions ] Q: What is the difference between an Upstream (A/F) Sensor and a Downstream (O2) Sensor? A: Upstream sensors (Air Fuel Ratio Sensors) are installed BEFORE the catalytic converter to measure air-fuel ratio for ECU fuel control. Downstream sensors are located AFTER the catalytic converter to monitor emissions and catalytic efficiency. This DENSO 234-5060 is an UPSTREAM sensor only. Q: How do I know if this sensor fits Bank 1 or Bank 2 on my vehicle? A: For most Nissan/Infiniti V6 and V8 engines, upstream sensors may differ slightly by bank (Left/Right or Front/Rear) due to harness length or plug design. Please verify your original sensor\'s plug shape, wire length, and location before ordering, or send us your VIN to confirm exact fitment. Q: Will replacing this sensor clear my Check Engine Light (CEL) automatically? A: Once installed, the Check Engine Light may take a few driving cycles to clear naturally, or you can clear the error codes (e.g., P0171, P0174, P0031) using an OBD2 scanner. If the light returns immediately, please inspect for vacuum leaks, wiring damage, or blown fuses. Q: Is this a genuine DENSO original equipment part? A: Yes, 100%. All our DENSO sensors are brand new, genuine OEM parts sourced directly in original packaging, ensuring exact factory performance and long service life. Q: Do I need anti-seize lubricant during installation? A: Yes, applying a small amount of high-temperature anti-seize compound to the sensor threads is recommended for smooth installation and future removal. (Avoid getting lubricant on the sensor tip/element). [ Warranty & Returns ]
