What does EGR delta pressure mean?

What does EGR delta pressure mean?

The EGR pressure feedback sensor, also known as the delta pressure feedback sensor, is a sensor that detects the pressure changes in the EGR system. It works together with the EGR valve to regulate the pressure of the EGR system.

Where is the EGR differential pressure sensor?

The EGR differential pressure sensor measures the exhaust gas pressure drop across the EGR differential pressure orifice. This pressure drop is used to calculate the amount of EGR flow into the intake manifold. ISM02 (CM870 and CM570) and ISM04 (CM875) engines: The sensor is located on the air intake manifold.

What does the EGR differential pressure sensor do?

SENSOR & EMISSION COMPONENT o DPFE (Differential Pressure Feedback Electronic) Sensors are an integral part of the EGR (Exhaust Gas Recirculation) System. The DPFE Sensor provides information to the Powertrain Control Module (PCM) to tell it how much exhaust gas is flowing through the system.

How do you calibrate a pressure sensor?

Pressure Sensor Calibration procedure.

  1. Once it is properly set up and has stabilized, pump the necessary pressure.
  2. Supply an increasing pressure. S imulate at least 5 setpoints covering the entire range.
  3. Then apply pressure in decreasing order once the maximum pressure is reached.
  4. Record in your Measurement Data Sheet.

Can a check engine light be set off by an EGR sensor?

If the computer detects any problem with the EGR pressure sensor signal or circuit, it will illuminate the Check Engine Light in order to notify the driver of an issue. A Check Engine Light can be set off by a wide variety of issues so having the computer scanned for trouble codes is highly recommended.

What are the symptoms of a bad EGR pressure sensor?

Check Engine Light comes on Another symptom of a problem with the EGR pressure sensor is a Check Engine Light. If the computer detects any problem with the EGR pressure sensor signal or circuit, it will illuminate the Check Engine Light in order to notify the driver of an issue.

How does the EGR system in a car work?

Many modern vehicles are equipped with an EGR system to help lower the vehicle’s emissions. The EGR system works by recirculating exhaust gases back into the engine in order to lower cylinder temperatures and NOx emissions. The EGR system is made up of several components that work together to accomplish this task.
