Oxygen Sensor for 2004-2007 Ford Focus - Bosch 15802

Bosch 15802 oxygen sensor for the 2004-2007 Ford Focus 4-cylinder 2.3L and the 2005-2006 Focus 4-cylinder 2.0L sends air-fuel-ratio readings to the ECU. This Bosch O2 sensor is a downstream, narrow-band heated unit that helps the ECU keep combustion stable and emissions down.

• Metal housing and a TSP coating that resists 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 failing oxygen sensor can show up as a check engine light, a rougher idle or poorer fuel economy, and other faults can trigger these too. Find the cause first: with the engine off and cool, look over the wiring and connector for melted insulation or chafing. A shop can test the signal itself.
