NTK Exhaust Gas Temperature Sensor - VW166J-EWE (NGK 92489)

Exhaust Gas Temperature (EGT) Sensors monitor the temperature of the exhaust gas, ensuring that exhaust gas cleaning components achieve optimal conversion rates. NGK has been developing EGT sensors for OE and the Aftermarket for many years.

When it comes to the installation position of EGT Sensors, NGK supplies products such as vehicle-specific sensors that:

• measure the exhaust gas temperature before and after the turbocharger
• measure the exhaust gas temperature before and after the diesel oxidation catalytic converter
• are fitted before/after the diesel particulate filter and/or the 3-way catalytic converter

EGT Sensors serve as a temperature monitor for turbochargers, catalytic converters, diesel particle filters, and nitrogen oxide reduction systems.

They are used to monitor the optimum operating point, to protect the relevant components from temperature overload, and to keep them in the desired temperature range for optimal conversion rates, thus making them an important component for the reduction of harmful emissions from vehicles.
