Bosch T2H48051 Oxygen Sensor Sensor Heated - O2 4-Wire

The Bosch T2H48051 is a premium heated oxygen sensor designed for precise emissions control and optimal engine performance. This OE-quality sensor monitors oxygen levels in the exhaust system, providing critical feedback to the engine control unit to maintain the ideal air-fuel ratio and reduce harmful emissions.

Key Features:

• Heated 4-wire design for faster response and accurate readings
• Stainless steel body sealed tight to protect against exhaust emissions damage
• Advanced ceramic sensing element for reliable voltage generation
• Factory tested to meet Bosch's rigorous quality standards
• OE-specification sensor manufactured by the world's largest automotive supplier
• Direct-fit replacement for OEM part number T2H48051

Oxygen sensors detect oxygen content in exhaust gases and generate an electrical signal that the ECU converts to oxygen level readings. Over time, continuous exposure to extreme exhaust temperatures can cause sensor degradation, leading to incorrect readings, poor fuel economy, reduced engine performance, and illuminated check engine lights. Replacing a worn oxygen sensor restores proper air-fuel mixture control and helps your engine operate efficiently while minimizing emissions.
