Hella 014494741 Exhaust Gas Temperature (EGT) Sensor - Rear

HELLA EGT Sensor for Mercedes-Benz

HELA Exhaust Gas Temperature Sensor Part Number 014494741 provides real-time exhaust temperature monitoring for emission-controlled diesel applications. It is built for OE-level signal accuracy and a direct-fit installation on select Mercedes-Benz E350 and E320 models.

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• 2-pin connector with bolted mounting design
• 660 mm cable length for the listed applications
• Monitors exhaust heat to help protect the turbocharger and DPF
• Direct replacement for select Mercedes-Benz E350 and E320 vehicles

Detailed Application and Function

This HELLA EGT sensor is used to measure exhaust gas temperature so the engine control system can manage heat-sensitive components and emissions strategy. On Mercedes-Benz E350 and Mercedes-Benz E320 diesel applications, accurate temperature feedback helps maintain proper exhaust aftertreatment operation and supports protection of the turbo and diesel particulate filter. Part Number 014494741 is engineered for the listed rear and N/A positions with the specified 2-pin, bolted configuration.

This part cross-references Bosch 12112 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature readings
• Incorrect EGT signal data affecting emissions control
• Heat-related stress on turbocharger and DPF components
• Driveability issues tied to exhaust aftertreatment monitoring
• Replacement needs for a damaged or aging Mercedes-Benz EGT sensor

Installation Notes

Verify connector style, mounting type, cable length, and position before installation. This sensor uses a 2-pin connector and bolted mounting, with a 660 mm lead length. Confirm the vehicle application against the listed fitment for 2011-2013 Mercedes-Benz E350, rear, and 2007-2009 Mercedes-Benz E320, N/A. Part Number 014494741 should be matched to the original sensor location and configuration for proper operation.

Quality Assurance

HELLA supplies OE-focused electrical and sensor components, and this EGT sensor is built to meet the precision required for exhaust temperature monitoring in modern emissions systems.
