On Mercedes-Benz E250 diesel applications, accurate EGT data helps the engine management system respond to rising temperatures before heat-related damage affects the turbo, DPF, or other emissions components. This part cross-references Delphi TS30313 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues It Can Help Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFault codes related to exhaust gas temperature readings\u003c\/li\u003e\n\u003cli\u003eIncorrect temperature data from a failing EGT sensor\u003c\/li\u003e\n\u003cli\u003eReduced emissions-system monitoring accuracy\u003c\/li\u003e\n\u003cli\u003eHeat stress on turbocharger and DPF components\u003c\/li\u003e\n\u003cli\u003eDriveability issues tied to exhaust temperature sensor failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 2014-2016 Mercedes-Benz E250, location-exhaust pipe. Verify connector style, cable length, and bolted mounting location before installation. Use the vehicle’s service information to confirm sensor placement and routing, and inspect the exhaust pipe area for heat damage or corrosion that could affect the new sensor. Part Number 014494891 should be matched to the original sensor application before replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eHELLA manufactures this EGT sensor to OE-level precision for consistent temperature measurement and dependable emissions-system operation.
