An integral part of your vehicle's EGR (exhaust gas recirculation) system is the EVP position sensor. This sensor does the important job of sensing the throttle position so gases can pass into the intake manifold. The information this sensor collects is sent to the engine control module so it can make the necessary adjustments to the EGR valve flow. With this information, the engine can run at peak efficiency and also reduce emissions.

This sensor always works, because it sends information literally many times per second. With that said, it takes quite a bit of beating over time. What's tricky is that many of the signs of an EVP position sensor no longer working are also the same signs of other issues and problems. Therefore, it is very important to entrust car diagnostics to AvtoTachki professionals, who will accurately determine the problem and how best to proceed.

Here are some of the signs that may signal that it's time to replace the EVP position sensor:

  • When you start the car in the cold, it can be quite difficult to start it, and when it does, it can continue to run rough until it warms up.

  • Most likely the Check Engine light will come on. This is where diagnosis is all the more important as the mechanic can read the computer codes to determine the exact cause of the warning light.

  • If you just attempted a fog test and failed, the EVP position sensor may no longer be working properly. If this is indeed the problem, replacing it should allow your vehicle to pass the inspection.

There are many parts involved in your car's EGR system and one of those parts is the EVP position sensor. This part works constantly, sending important information to the engine control module many times every second. Once this part fails, your engine will not be able to run efficiently and you will probably fail the smog test. If you are experiencing any of the above symptoms and suspect that your EVP position sensor needs to be replaced, have a diagnosis or have an EVP position sensor replaced by a certified mechanic.
