In today's world, people are more aware of exhaust fumes than ever before. At the same time, measures designed to reduce emissions into the atmosphere have been built into modern cars. Your vehicle has an integrated EGR pressure feedback sensor. EGR stands for Exhaust Gas Recirculation, which is a system that does just that - recirculates exhaust gases back into the intake manifold so they can be burned along with the air/fuel mixture.

Now, as far as the EGR pressure feedback sensor is concerned, this is the sensor that affects the EGR valve. It is this sensor that is responsible for measuring the pressure at the outlet and inlet on the EGR tube. The car relies on the readings of this sensor to ensure that the engine receives the correct amount of exhaust gases.

While it would be great if this sensor lasted the lifetime of your car, the fact is that it has been known to fail "prematurely". The main reason for this is that he constantly deals with very high temperatures, and these temperatures take their toll on him. You don't want to leave a sensor damaged because if it doesn't work properly, you could fail an emissions test, risk engine damage, and more. Here are some signs that may signal that your EGR pressure feedback sensor is nearing the end of its life:

• The Check Engine light should come on as soon as the EGR pressure feedback sensor fails. This will be due to pop-up DTCs related to the powertrain control module.

• If you need to pass a smog or emissions test, there is a good chance your car will break down. Without the correct operation of the sensor, it will not send the correct amount of exhaust gases back into the recirculation.

• Your engine will not run as smoothly as it should. You may hear a knocking noise from the engine, it may run "rough" and you risk damaging the engine.

The EGR pressure feedback sensor is important to ensure that the correct amount of exhaust gas is recirculated. The part is notorious for failing earlier than it should, mostly due to the high temperatures it is regularly exposed to. If you are experiencing any of the above symptoms and suspect that your EGR pressure feedback sensor needs to be replaced, have a diagnosis or have the EGR pressure feedback sensor replaced by a certified mechanic.
