What is the Engine EGR pressure feedback sensor?
The EGR pressure feedback sensor is a vital component of the EGR (exhaust gas recirculation) system, which helps to reduce harmful emissions by recirculating a portion of the exhaust gases back into the engine’s combustion chamber. The sensor measures the pressure of the exhaust gases as they pass through the EGR valve and sends this information to the engine’s computer, which uses it to adjust the flow of exhaust gases and maintain optimal performance.
If the EGR pressure feedback sensor fails, it can cause a variety of issues, including:
- Decreased fuel efficiency
- Increased emissions
- Engine misfires
- Reduced power and acceleration
If you are experiencing any of these issues, it may be time to replace your EGR pressure feedback sensor. This is a fairly straightforward repair that can usually be done in a few hours.
The EGR pressure feedback sensor is an important part of your car’s EGR system. It monitors the pressure in your EGR system and uses this information to control the EGR valve. When pressure is low, the feedback sensor will send a signal to open the valve and increase flow. When the pressure becomes too high, it will close the valve.
Problems with the EGR pressure sensor can lead to the valve not opening and closing when it should. This can adversely affect your engine’s performance, fuel economy and increase harmful exhaust emissions.
Symptoms of a damaged EGR pressure feedback sensor:
Reduced engine performance – A malfunctioning EGR pressure feedback sensor can prevent exhaust gas from properly circulating the engine. Thie usually results in decreased engine performance. You may experience reduced engine power, increased fuel consumption and stalling while you are driving.
Increased emissions – When the pressure feedback sensor malfunctions, an increase in exhaust emissions can occur. This can lead to your car failing its Warrant of Fitness.
Check engine light – When the engine EGR pressure feedback sensor malfunctions, it can affect the air/fuel ratio in your car’s engine. This can lead to the check engine light turning on.
Failed WOF for EGR pressure feedback sensor?
During your car’s Warrant of Fitness inspection, the exhaust will be tested to ensure it is not producing excess emissions. If the EGR or other component is faulty, it can cause your vehicle to fail its WOF. An EGR sensor replacement will usually fix this issue, as it will allow the EGR system to function correctly.
