Delphi TS30143 Exhaust Gas Temperature (EGT) Sensor - Before Turbocharger

Delphi TS30143 Exhaust Gas Temperature Sensor

The Delphi TS30143 Exhaust Gas Temperature (EGT) Sensor is built for precise exhaust monitoring in diesel emission control systems. It is a direct-fit style replacement for select Volkswagen Golf, Volkswagen Jetta, and Audi A3 applications with the sensor mounted before the turbocharger.

Delphi draws on OE engineering experience to build aftermarket parts with the same application knowledge used by major automakers. The TS30143 uses a threaded nut mounting design, an oval female connector, and a 2-terminal blade connection for a secure electrical interface.

• Package contents: EGT sensor and instruction sheet

Detailed Description

Delphi TS30143 is an exhaust gas temperature sensor engineered for vehicles that rely on accurate pre-turbo exhaust temperature feedback to manage emissions and engine protection strategies. It is a strong match for drivers searching for a 2011-2014 Volkswagen Jetta before turbocharger EGT sensor, a 2012-2014 Volkswagen Golf before turbocharger sensor, or a 2011-2013 Audi A3 before turbocharger sensor. This part number, TS30143, is also referenced for OE-style replacement needs where the original sensor uses the same connector and mounting layout.

This part cross-references 03L 906 088 EJ for the same application. Delphi’s OE heritage and supplier experience are reflected in the application-specific design and connector configuration.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings before the turbocharger
• Emission control system monitoring issues
• Engine protection strategies affected by inaccurate EGT input
• Drivability concerns tied to failed exhaust temperature sensing

Installation Notes and Tips

Install the TS30143 in the before-turbocharger position only when the vehicle application matches the listed fitment. Confirm the oval female connector, 2-terminal blade interface, and threaded nut mounting style before installation. Verify harness routing and connector engagement to help ensure a secure electrical connection. Fits 2012-2014 Volkswagen Golf, before turbocharger. Fits 2011-2014 Volkswagen Jetta, before turbocharger. Fits 2011-2013 Audi A3, before turbocharger.

Quality Assurance

Delphi builds this EGT sensor using OE experience and application knowledge developed through long-term supplier relationships with major automakers. The TS30143 is manufactured to support accurate exhaust temperature sensing in the specified Volkswagen and Audi applications.
