The EGPS (Exhaust Gas Pressure Sensor) is a differential sensor measuring the pressure difference between gas in the intake and the outtake of the Particulate Filter.
The EGPS is more a sensor in the pollution regulation systems for Diesel engines.
The sensor is found in Diesel Particulate Filter Systems with additive (FAP) and with no additive (DPF).
When the Particulate Filter is saturated, the EGPS monitors the level of saturation by measuring the pressure difference before and after the filter.
The filter saturation level is controlled by the EGPS, by Temperature Sensor placed before and after the filter and by Mass Airflow Sensor too.
- Unnecessary filter regeneration;
- Power losses if the sensor is not detecting the filter saturation level;
- Dashboard light for Particulate Filter and blinking light pre-heating;
- Reduction of filter lifespan due to unnecessary regenerations;
- Increase in oil consumption;
- Increase in pollution levels.
