The exhaust gas recirculation (EGR) pressure sensor calculates the exhaust gas pressure inside the EGR system and sends it to the computer. The car's computer receives this data and it controls the EGR valve to lessen harmful emissions.
Exhaust Gas Recirculation pressure sensor conceptThe EGR pressure sensor is utilized to monitor the pressure in the EGR system. The EGR is part of the car's emissions control system and with the sensor, the engine control module will calculate the pressure and use it to control the EGR pressure. The sensor will report new pressure values when changes are made while calculating the pressure.
EGR pressure sensor functionThe EGR pressure sensor utilizes the pressure in the EGR system to calculate how much pressure is put down on the EGR system. The engine control software will use the engine speed and load information from the feedback sensor to increase or reduce pressure on the EGR system for the best performance.
Common issues with a failing EGR pressure sensorA failing EGR pressure can cause the vehicle to rough idle, hesitate, and a decline in engine performance.
