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

What It Helps Address

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

Installation Notes

Confirm the vehicle is a 2000-2004 Volvo S40 or 2000-2004 Volvo V40 with an upstream oxygen sensor application before ordering. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life and affect signal quality. Verify the threaded mounting location, connector shape, and harness length against the original part to ensure proper fitment.
