Exhaust Gas Temperature Sensor Resistance

The sensor is a negative coefficient type thermistor sensor converting heat into resistance.

Exhaust gas temperature sensor resistance.

At the same time measures to reduce co2 and exhaust emissions by addressing environmental issues require efforts to develop engines with higher efficiency. By monitoring egt the driver or pilot can get an idea of the vehicle s air fuel ratio afr. Changes in temperature result in changes in resistance of the sensor and this is communicated to the ecu as a voltage. The sensor output voltage varies with the exhaust catalyst dpf temperature and becomes lower as the catalyst temperature rises.

A short in the exhaust gas temperature sensor. A decrease in back pressure most commonly caused by an aftermarket off road exhaust system. Typically measuring temperatures up to 900 c in the exhaust system the resistance of the egt sensing element alters with the change in exhaust temperature. In this article we present tdk temperature sensors ntc thermistors and.

The sensor is supplied with 5 volts from the ecm. With the aid of egts the ecm can accurately monitor the exhaust catalyst. In stock on october 5 2020. Whilst the more common ptc sensors function by increasing their resistance with increasing exhaust gas temperature the ntc sensors decrease their resistance with a subsequent temperature.

At a stoichiometric air fuel ratio the exhaust gas temperature. Automobiles are entering a period of change and technological innovation supporting electrification and its widespread adoption are becoming important issues. A faulty exhaust gas temperature sensor. The main measurement methods used for the determination of exhaust gas temperatures include resistance temperature sensors and thermocouples resistive sensors commonly used for engine exhaust gas applications include platinum resistance sensors such as pt200 and ntc thermistors.
