The Exhaust Gas Pressure Sensor (EGPS) or\u00a0Diesel Particulate Filter (DPF)\u00a0measures the exhaust gas pressure upstream and downstream\u00a0of the Particle Filter. By monitoring the pressure difference between these two points, the saturation\u00a0level of the Particle Filter can be determined. This information allows the emission control system to\u00a0perform the regeneration of the Particle Filter, according to the European emission standards.<\/i><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The EGPS allows monitoring the Particulate Filter saturation by measuring the pressure difference\u00a0before and after the filter. The saturation is also controlled by the Temperature Sensors placed before\u00a0and after the filter and by an intake Mass Airflow Sensor.
<\/i>Once the filter\u2019s saturation is determined, the regeneration routine will be started by the system\u00a0<\/i><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    A careful visual inspection is the first step for the diagnosis of a problem.
    <\/i>Check for cracks, bumps or any damage to the sensor\u2019s housing and connecting pipes.
    <\/i>Make sure there is no air leakage in the sensor, pipes and connecting joints.
    <\/i>Also, check for signs of wear in the connector or wirings that could lead to electrical problems.
    <\/i>If none of the problems above have been observed, the failure can be due to a damaged sensing\u00a0element inside the sensor.
    <\/i>Failure causes can be;
    <\/i>\u2022 Breaks, pores or cracks in the pipes.
    <\/i>\u2022 Wear signs in the connector or wirings
    <\/i>\u2022 Damage of the sensing element causing bad pressure readings
