Hella 014494201 Exhaust Gas Temperature (EGT) Sensor

Hella Exhaust Gas Temperature Sensor 014494201

The Hella 014494201 exhaust gas temperature (EGT) sensor monitors exhaust heat levels before the pre-catalyst on select Audi and Volkswagen diesel applications. With a 230 mm cable, 2-pole connector, and bolted mounting type, it is built for direct replacement service where accurate exhaust temperature feedback is required.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• 230 mm cable length for the specified vehicle routing
• 2-pole electrical connection
• Bolted mounting type for secure installation
• Location before the pre-catalyst
• Hella part number 014494201

Detailed Description

This Hella EGT sensor is used in emission control monitoring on 2009-2012 Audi Q7 and 2009-2010 Volkswagen Touareg applications. The sensor measures exhaust gas temperature ahead of the pre-catalyst, helping the engine management system track thermal conditions in the exhaust stream. If you are searching for an Audi Q7 exhaust gas temperature sensor or a Volkswagen Touareg pre-catalyst EGT sensor, part number 014494201 matches the listed fitment and connector specifications.

This part cross-references Gates 12489 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensing
• Incorrect exhaust temperature readings before the pre-catalyst
