FAQ Q&A

Q: How do I know if this sensor fits my vehicle?

A: Please verify your original part number matches any of the listed OEM numbers: 89467-48280, 89467-0E250, or 234-9154. You can also check your vehicle year, make, and model in the fitment guide to ensure compatibility.

Q: Is this an upstream or downstream oxygen sensor?

A: This is an upstream sensor (Bank 1 Sensor 1 or Bank 2 Sensor 1), which is located before the catalytic converter to monitor air-fuel ratios and assist the ECU in engine management.

Q: Do I need to program my ECU after replacing this sensor?

A: No programming is required. However, it is recommended to disconnect the battery for a few minutes or use an OBDII scanner to clear existing trouble codes (like P0031 or P0171) once the new sensor is installed.
