Bosch 13862 Oxygen Sensor - Downstream, Upstream Left or Upstream Right

Bosch Actual OE Oxygen Sensor 13862

Bosch 13862 is a narrow-band heated oxygen sensor built for specific Mercedes-Benz applications that require accurate air-fuel ratio feedback to the ECU. It supports stable combustion control, faster closed-loop response, and lower emissions across changing engine conditions.

As part of Bosch’s Actual OE Oxygen Sensor line, this sensor reflects Bosch’s long OE development history in oxygen sensing technology. The design uses advanced ceramic elements, optimized heater control, and high-temperature-resistant materials for consistent signal quality in demanding thermal and vibration environments.

Key Features

• Specific-fit Bosch oxygen sensor for direct application matching
• Narrow-band heated sensor type for precise switching-type signal output
• 4-wire design with included wiring harness and round female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and steel finish for durability in exhaust service
• OE-proven Bosch engineering for stable closed-loop fuel control

Application Details

Compatible With 1999-2002 Mercedes-Benz SL500, downstream; 1998-1999 Mercedes-Benz E320, upstream left; 1998-1999 Mercedes-Benz E430, upstream right; 1999 Mercedes-Benz E55 AMG, upstream right; 1997 Mercedes-Benz E320, downstream; and 1997 Mercedes-Benz E420, upstream right. Bosch 13862 is the correct style of replacement for Mercedes-Benz oxygen sensor service where the original sensor uses a narrow-band heated configuration.

This part cross-references Bosch 0005409017 for the same application.

What It Helps Address

• Faulty oxygen sensor signal causing rich or lean fuel trim conditions
• Delayed closed-loop operation after startup
• Check engine light concerns related to oxygen sensor performance
• Reduced fuel control accuracy during normal driving
• Emissions test failures tied to sensor response or aging

Installation Notes

Verify the sensor position, connector style, and thread size before installation. This Bosch oxygen sensor uses a threaded mount, 4-wire harness, and round female connector, so the existing exhaust bung and vehicle connector should match the original configuration. Use proper oxygen sensor service tools and follow the vehicle manufacturer’s torque and routing specifications to avoid harness damage or exhaust leaks.

Quality Assurance

Bosch supplies this Actual OE Oxygen Sensor line with OE-proven design principles developed over decades of oxygen sensor engineering. The sensor is built for consistent signal output, heater performance, and durability under exhaust heat and vibration.
