Delphi TS30140 Exhaust Gas Temperature (EGT) Sensor - Before Turbocharger

Delphi TS30140 Exhaust Gas Temperature Sensor

The Delphi TS30140 Exhaust Gas Temperature (EGT) Sensor is built for direct replacement in emission control systems that monitor exhaust heat before the turbocharger. It is a fitment-specific solution for 2009-2012 Audi Q7 and 2009-2012 Volkswagen Touareg applications with before turbocharger placement.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control monitoring
• Fits before turbocharger locations on select Audi Q7 and Volkswagen Touareg models
• Maximum temperature rating of 850.0
• 11.22 wiring harness length for application-specific routing
• Oval female connector with blade terminals
• 2-terminal design with male terminal gender
• Threaded nut mounting type
• Includes exhaust gas temperature sensor and instruction sheet

Detailed Description

Delphi TS30140 is an OE-style exhaust gas temperature sensor engineered for vehicles that rely on accurate exhaust heat data to manage emissions and turbocharger protection. Delphi draws on more than 100 years of OE experience and supplier knowledge, and that background is reflected in the sensor design, connector layout, and mounting style. This part cross-references 059 906 088 A and 231022 for the same application.

Compatible With 2009-2012 Audi Q7, before turbocharger, and 2009-2012 Volkswagen Touareg, before turbocharger. If you are replacing a failing Delphi TS30140 sensor on an Audi Q7 or Volkswagen Touareg, this part is matched to the listed position and connector configuration for straightforward service selection.

What It Is Used For

• Replacing a faulty EGT sensor that can trigger emissions-related fault codes
• Restoring exhaust temperature monitoring before the turbocharger
• Addressing drivability issues tied to incorrect exhaust heat readings
• Supporting proper turbocharger and aftertreatment system control
• Correcting warning lights caused by sensor signal loss or drift

Installation Notes and Tips

Verify the before-turbocharger location, connector shape, terminal count, and harness length before installation. Compare the original sensor and connector to the Delphi TS30140 to confirm the threaded nut mounting style and application match. On Audi Q7 and Volkswagen Touareg models, inspect the surrounding exhaust components for heat damage, corrosion, or wiring wear before installing the new sensor.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The TS30140 is designed to meet the demands of exhaust temperature monitoring in emission control service.
