How Long Does an EGR Pressure Feedback Sensor Last?

EGR Pressure Feedback Sensor

In today's world people are more aware of exhaust gases than ever before. With that said measures have been built into modern vehicles that are meant to cut down on the emissions released into the air. Built into your vehicle is an EGR pressure feedback sensor. The EGR stands for exhaust gas recirculation, which is a system that does just that - recirculate exhaust gases back into the intake manifold so they can be burned with the fuel/air mixture.

Now as for the EGR pressure feedback sensor, this is a sensor that contributes to the EGR valve. This particular sensor is responsible for measuring the pressure at the exhaust and intake on the EGR tube. The vehicle counts on this sensor to read correctly so that the engine receives the right amount of exhaust gas.

While it would be great if this sensor would last the life of your vehicle, the fact of the matter is that it’s known to breakdown "prematurely". The main reason for this is that it is constantly dealing with very hot temperatures, and these temperatures take a toll on it. You don't want to leave the sensor damaged because if it isn't working properly you can fail an emissions test, risk damaging your engine, and more. Here are some signs to look for that may signal your EGR pressure feedback sensor has hit the end of its lifespan:

  • The Check Engine Light should come on once the EGR pressure feedback sensor fails. This will happen because failure codes pop up regarding the power train control module.

  • If you need to pass a smog or emissions test, there's a good chance your vehicle will fail. Without the sensor working properly, it won't be sending the correct amount of exhaust gases back to recirculate.

  • Your engine won't run as smoothly as it should. You may hear a knocking sound in the engine, it could run "rough", and you will be risking engine damage.

The EGR pressure feedback sensor is important in making sure the correct amounts of exhaust gases are recirculated. The part is known for failing earlier than it should, mainly because of the high temperatures it is exposed to on a regular basis. If you’re experiencing any of the above mentioned symptoms and suspect your EGR pressure feedback sensor is in need of replacement, get a diagnostic or book an EGR pressure feedback sensor replacement from a certified mechanic.
