What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect air-fuel feedback
• Higher fuel consumption from inaccurate exhaust readings
• Increased exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Fits 2006 Suzuki Verona, upstream. Confirm the cylinder-bank application and sensor lead length before installation, since the fitment notes list both 500 mm and 600 mm configurations for Cyl 1-3 and Cyl 4-6. Inspect the sensor, wiring harness, and connector for physical damage before replacement, and verify the threaded mounting point is clean and undamaged. Part number 350-34393 should be matched to the exact vehicle application and connector style before installation.
