Detailed Description
Walker Products Aftermarket 350-33030 is an emission control sensor designed to provide ECU feedback for the air-fuel management system. For 1995 Hyundai Accent applications, this upstream oxygen sensor helps the engine control module monitor exhaust oxygen content so fuel delivery and emissions control can stay within expected operating parameters. Walker Products has long focused on engine management and oxygen/air-fuel sensor replacement parts, and this part number is built for the specified fitment position rather than a universal installation.
This part cross-references common OE-style oxygen sensor applications for the same vehicle position. If you are replacing a 1995 Hyundai Accent upstream oxygen sensor, 350-33030 is the part number to verify against the original sensor configuration.
What It Is Used For
- Check engine light related to upstream oxygen sensor faults
- Poor fuel economy caused by inaccurate exhaust feedback
- Rough running or inconsistent air-fuel control
- Elevated exhaust emissions from a failing sensor
- Stored ECU fault codes tied to the oxygen sensor circuit
Installation Notes and Tips
Confirm the vehicle is a 1995 Hyundai Accent with the upstream sensor location before ordering. Inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals before installation. Because this is a threaded, specific-fit sensor, match the connector shape, wire count, and mounting style to the original part for proper installation and ECU feedback.
Quality Assurance
Walker Products manufactures engine management sensors as OE replacement parts and operates as an ISO 9001/TS 16949 certified company. The 350-33030 is produced for the listed application and fitment position to support correct diagnostic system response.
