Bosch 0 258 017 224 Oxygen Sensor Lambda Sensor 5-Wire Heated

The Bosch 0 258 017 224 is a high-quality oxygen sensor (also known as a lambda sensor) designed for precise air-fuel ratio measurement in automotive exhaust systems. This heated 5-wire sensor is located before the catalytic converter and monitors the amount of unburned oxygen in the engine's exhaust gases, sending signals to the engine control unit to optimize combustion efficiency and reduce emissions.

Key Features:

• 5-wire heated oxygen sensor design for faster response and accurate readings
• Pre-catalyst placement (upstream, front position)
• Vehicle-specific connector for direct-fit installation
• Manufactured to OE specifications for reliability and long service life
• Cable length approximately 56 inches from sealing surface to connector end
• Functionally and quality tested to OEM standards

OEM Cross-Reference Numbers: Porsche 9A1 606 123 01, 9A1 606 123 02, 948 606 131 01; Bosch 0 258 017 225, 17224

Benefits: Proper oxygen sensor function is critical for fuel economy, engine performance, and emissions control. A faulty oxygen sensor can waste up to 30% of fuel, cause engine hesitation or surging, trigger check engine lights, and lead to failed emissions tests. Regular replacement every 60,000 to 90,000 miles helps maintain optimal engine efficiency and prevents potential catalytic converter damage.
