To help reduce engine emissions, cars have a so-called EGR system, which is an exhaust gas recirculation system. The principle of its operation is that the exhaust gases are added back to the fuel-air mixture. The reason for this is that any fuel left in the exhaust burns off and then cools the combustion chamber. This process results in much less nitrogen oxides.
The current version of the EGR system uses an EGR control solenoid. This solenoid is responsible for detecting the amount of exhaust gases entering the intake process. Because this solenoid is an electrical component, it can fail over time. It is important to note that it should not need regular maintenance or repair, but it may need to be replaced from time to time. Overall, it's safe to say that this part is designed to last the lifetime of your vehicle. Unfortunately, once this part fails, it will need to be completely replaced as you will not be able to repair it.
Here are a few warning signs that the EGR control solenoid is nearing the end of its life:
The Check Engine light may come on as soon as it starts to fail. This will mess with how the engine works, so your light should come on. Keep in mind that the Check Engine indicator can mean a wide variety of things, so it's important not to jump to conclusions.
At idle, your car may stall or become rough. This may be due to the EGR control solenoid stuck in the open position.
When accelerating while driving, you may hear a knock in the engine or even a "knock". The reason this can happen is that the control solenoid is not opening properly, possibly sticking.
While the EGR control solenoid is designed to last the lifetime of your vehicle, something can happen and it could fail sooner than intended. It can fail, fail, or simply wear out.
Once your EGR control solenoid fails, you will need to replace it fairly quickly. If you experience any of the above symptoms and suspect that the EGR lockout solenoid needs to be replaced, have the EGR lockout solenoid replaced or serviced by a professional mechanic.
