As you might imagine, exhaust temperature sensors (sometimes called EGTSs) measure the temperature of exhaust gases from internal combustion engines. The sensor wants to keep the temperature of the exhaust gas within a range that it knows to be safe for the operation of the engine and will alert the ECU if things get too hot. If that happens the ECU can decide to dump more fuel into the engine’s cylinders which cools things down to a safe temperature. Exhaust gases that are too hot can cause damage to catalytic converters, diesel particle filters, and nitrogen oxide reduction systems. Exhaust temperature sensors are very important in air-cooled cars and are also useful for fine-tuning turbocharged engines.

Exhaust temperature sensors can be damaged by impacts, excessive vibration, or even during repairs to another part of the exhaust system. A damaged sensor can lead to damage to the components mentioned above and can also cause the engine to run rich thanks to the ECU adding more fuel to the air/fuel ratio in an attempt to cool things down. Smelling unburnt gas and seeing your fuel economy take a dive can be warning signs that all is not well with your exhaust temperature sensor.
