Walker 350-34817 Oxygen Sensor - Downstream or Upstream

Walker 350-34817 Oxygen Sensor Overview

Walker 350-34817 is an OE-style oxygen sensor built for specific vehicle applications and ECU feedback requirements. It is engineered to match the intended fitment position and help maintain accurate exhaust monitoring on compatible vehicles, including select Honda Civic and Toyota Camry applications.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct replacement use. The 350-34817 follows that approach with application-specific design for the correct mounting location and diagnostic signal output.

Key Features

• OE replacement oxygen sensor for emission control systems
• Application-specific fitment position for proper installation
• Provides ECU feedback for exhaust monitoring
• Built for Walker Products engine management applications
• Walker 350-34817 part number for catalog and service matching

Product Details

The Walker 350-34817 oxygen sensor is designed for vehicles that rely on precise exhaust-gas feedback to manage fuel delivery and emissions performance. When an oxygen sensor begins to fail, the engine may run poorly, fuel consumption can increase, exhaust emissions can rise, and the malfunction indicator light may illuminate. This sensor is intended as a direct replacement for the specified application and position, helping restore the signal the ECU expects from the exhaust system. Walker Products has supplied engine management components since 1946, and the 350-34817 reflects that focus on application-specific replacement parts.

Compatible With select Honda Civic and Toyota Camry applications where this exact Walker 350-34817 sensor is specified.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Rough engine operation from incorrect air-fuel feedback
• Higher fuel use caused by inaccurate exhaust readings
• Increased exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Verify the sensor location, connector style, and harness routing before installation. Inspect the wiring harness and connector for heat damage, corrosion, or physical wear, since damaged components can shorten sensor life and affect readings. Confirm the vehicle application against the part number 350-34817 before ordering or installing.

Quality Assurance

Walker Products is an Automotive ISO 9001 / TS 16949 certified company. The Walker 350-34817 is manufactured as an application-specific replacement sensor for the intended vehicle fitment and ECU feedback requirements.
