Bosch 0986259063 Exhaust Gas Temperature EGT Sensor

The Bosch 0986259063 is an OE-replacement Exhaust Gas Temperature (EGT) Sensor designed for diesel-powered vehicles. Mounted before the turbocharger, this sensor detects exhaust gas temperature, converts it into a voltage signal, and feeds that data to the engine ECU to help control engine conditions and reduce emissions.

Key Features:

• Real-Time Temperature Monitoring: Provides accurate, continuous exhaust temperature data to protect critical engine and aftertreatment components
• ECU Integration: Supplies the engine control unit with critical data to optimize fuel dosing and initiate DPF regeneration events at the correct time
• Durable Construction: Built with heat-resistant materials including a stainless steel housing, ceramic insulators, and glass-to-metal hermetic seals — rated to withstand exhaust temperatures exceeding 1,600°F
• OE-Validated: Engineered and validated to original equipment standards for direct-fit replacement
• Fitting Position: Before turbocharger
• Thread Size: M14 x 1.5
• Cable Length: 606 mm (approximately 23.9 in)
• Connector Terminals: 2

OEM / Cross-Reference Part Numbers: 03G906088A, 03G906088AM, 03G906088AN, 03G906088AT, 03G906088J, 03L906088BS

By keeping DPF, SCR, DOC, and turbocharger systems within their optimal thermal operating range, the Bosch 0986259063 EGT sensor helps prevent costly component damage, supports efficient emissions regeneration, and ensures reliable long-term performance under extreme thermal loads.
