Bosch 000-540-85-17 64 Oxygen Sensor OEM Heated 4-Wire

The Bosch 000-540-85-17 64 Oxygen Sensor is an OEM-quality heated oxygen sensor designed for precise exhaust gas monitoring and optimal engine performance. As the original inventor of the automotive oxygen sensor, Bosch brings decades of engineering excellence and proven reliability to this critical emissions control component.

Key Features:

• Four-wire heated oxygen sensor design for rapid operation
• Narrow-band heated sensing element provides accurate oxygen level readings
• Durable metal housing withstands extreme exhaust temperatures from 300°F to 700°F
• Built-in heating element reduces warm-up time for faster sensor activation
• 18mm thread diameter with 22mm hex size for secure mounting
• Integrated wiring harness included for direct installation
• Female pin-type connector with four terminals

How It Works:

This oxygen sensor continuously monitors the oxygen content in exhaust gases and sends voltage signals to the engine control unit (ECU). The ECU uses these readings to adjust the air-fuel mixture for optimal combustion, ensuring maximum fuel efficiency, reduced emissions, and proper catalytic converter operation. The integrated heating element allows the sensor to reach operating temperature quickly, providing accurate readings even during cold starts.

Quality and Construction:

Manufactured to Bosch's exacting OEM specifications, this sensor features high-quality materials built to withstand harsh operating conditions. Each sensor undergoes rigorous functional testing at temperatures exceeding 1,000°C and leak testing to ensure environmental and functional robustness. The sensor's construction protects against contamination and engine vibration for long-lasting reliability.
