Delphi TS30161 Exhaust Gas Temperature (EGT) Sensor - Front

Delphi TS30161 Exhaust Gas Temperature Sensor

The Delphi TS30161 is an exhaust gas temperature (EGT) sensor built for front-position applications on select Mercedes-Benz E350 models. It uses OE-based engineering from Delphi’s long history as a supplier to major automakers, with the sensor design focused on accurate temperature monitoring in the exhaust stream.

Compatible with 2011-2013 Mercedes-Benz E350 front applications, this Delphi EGT sensor is a direct-fit option for drivers replacing a failed exhaust temperature sensor on the Mercedes-Benz E350. The TS30161 part number is also useful when cross-checking OE references during diagnosis and replacement.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• Fits front position applications on 2011-2013 Mercedes-Benz E350
• Maximum temperature rating: 850.0
• 17.94 wiring harness length for application-specific routing
• Oval connector with male connector gender and female terminal gender
• 2-terminal blade connection with threaded nut mounting
• Package contents include the EGT sensor and instruction sheet
• Delphi part number TS30161 for catalog and cross-reference lookup

Detailed Description

Delphi TS30161 is an OE-style exhaust gas temperature sensor engineered for front installation on the Mercedes-Benz E350 from 2011 through 2013. As part of the emission control system, the sensor monitors exhaust heat levels so the vehicle’s control strategy can respond to operating conditions in the exhaust stream. Delphi’s OE heritage is reflected in the sensor’s application-specific connector design, threaded nut mounting, and harness length.

This part cross-references Mercedes-Benz OE number 000 905 72 04 for the same application. When searching for a Mercedes-Benz E350 front EGT sensor or a Delphi TS30161 replacement, verify connector shape, terminal layout, and mounting style against the original unit before installation.

What It Helps Address

• Check engine light related to exhaust gas temperature sensor faults
• Incorrect exhaust temperature readings in the emission control system
• Fault codes tied to front EGT sensor performance
• Reduced diesel or exhaust aftertreatment system monitoring accuracy
• Replacement needs after sensor heat damage or connector wear

Installation Notes and Tips

Confirm the front sensor location, oval connector, 2-terminal blade layout, and threaded nut mounting before installation. Compare the original harness routing and connector orientation to the Delphi TS30161 to ensure proper fitment on the Mercedes-Benz E350. Inspect the exhaust bung and surrounding wiring for heat damage, corrosion, or carbon buildup before installing the new sensor.

Quality Assurance

Delphi builds aftermarket parts using OE experience gained from supplying major automakers for decades. The TS30161 reflects that OE-based approach with application-specific design details intended to match the original front EGT sensor setup on 2011-2013 Mercedes-Benz E350 models.
