This part cross-references no listed aftermarket part numbers in the provided data.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from a failing upstream sensor
• Higher exhaust emissions from inaccurate ECU input
• Fault codes tied to the affected sensor circuit or connector

Installation Notes

Install Walker 350-34173 in the exact upstream position specified for your vehicle. Before replacement, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. Confirm thread size, connector shape, and harness length against the original part before installation.
