FAQ Q&A

Q: What is the difference between an Upstream and Downstream oxygen sensor?

A: The Upstream sensor (Sensor 1) measures the air-fuel ratio exiting the engine, while this Downstream sensor (Sensor 2) is located after the catalytic converter to monitor its cleaning efficiency.

Q: Will this sensor clear my 'Check Engine' light (CEL)?

A: If your CEL is triggered by error codes P0136, P0137, or P0138 (related to the downstream sensor), replacing it with this 89465-42230 unit will typically resolve the issue.

Q: Is this a genuine OEM part or an aftermarket replacement?

A: This is a premium aftermarket replacement part manufactured to match 89465-42230 specifications, offering original equipment performance and fitment at a more accessible price point.
