Bosch 15518 oxygen sensor for the 2002-2003 Nissan Altima 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust stream. It sends air-fuel-ratio readings to the ECU, which uses them for stable combustion control and to help reduce emissions.

• Heated narrow-band switching-type sensor with a fast signal to the ECU
• Metal housing, integrated heater element and TSP coating to resist vibration, corrosion and contamination
• Built to withstand exhaust streams up to 1,880°F
• Reaches operating temperature in under 10 seconds for quick closed-loop control

A worn sensor can show up as a check engine light, a failed emissions test or a change in fuel economy. These signs alone do not prove the sensor is the problem, because an exhaust leak is another common cause.

Fits

This oxygen sensor also fits the 2002-2003 Nissan Sentra 4-cylinder 2.5L and the 2005-2006 Nissan X-Trail 4-cylinder 2.5L. The fitment calls for one downstream sensor per car, and this listing is a single sensor.
