This part cross-references common aftermarket listings for the same application, including Bosch 15717 and Denso 234-4626.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation from incorrect air-fuel correction
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

• Confirm the exact year, make, model, and sensor position before ordering.
• Inspect the sensor wiring harness and connector for heat damage, corrosion, or abrasion before installation.
• Verify the threaded mounting location and connector style match the original sensor.
• Use the listed downstream or California-emissions position only where specified in the fitment data.
