How to Replace an Exhaust Gas Recirculation (EGR) Control Solenoid
Exhaust gas recirculation (EGR) systems are controlled by the EGR control solenoid, which is controlled by the powertrain control module (PCM).
How to Replace an Exhaust Gas Recirculation (EGR) Pressure Feedback Sensor
Exhaust gas recirculation (EGR) systems use a pressure feedback sensor to tell the powertrain control module (PCM) how much exhaust gas is flowing.
How to Replace an Exhaust Gas Recirculation (EGR) Valve
The exhaust gas recirculation (EGR) valve can cause drivability problems if it fails and should be replaced to avoid engine performance issues.
Symptoms of a Bad or Failing EGR Vacuum Modulator
Common signs include engine performance issues, the Check Engine Light coming on, and failing an emissions test.
Symptoms of a Bad or Failing EGR Cooler
Common signs include engine overheating, exhaust leaking, and the Check Engine Light coming on.
How Long Does an EGR Cooler Last?
Within your vehicle is a part called the EGR cooler. EGR stands for Exhaust Gas Recirculation. This cooler is responsible for taking care of the exhaust gases once they leave the engine....
How Long Does an EVP Shut Off Solenoid Last?
The EVP shut off solenoid is the EGR (exhaust gas recirculation) valve position sensor. With that said, it has a fairly important job to perform that will help ensure your...
How Long Does an EVP Position Sensor Last?
An integral part of your vehicle's EGR (exhaust gas recirculation) system is the EVP position sensor. This sensor has the important job of figuring out where the gate is positioned in...
How to Replace an Exhaust Gas Recirculation (EGR) Vacuum Modulator
The EGR vacuum modulator meters the EGR valve in some car systems. Some signs of a failing EGR vacuum modulator include stalling and a rough idle.
How Long Does an Exhaust Pressure Control Valve Last?
The exhaust pressure control valve is used in diesel vehicles as part of its EGR (exhaust gas recirculation) system. The EGR system is meant to bring down the amount of...
How to Clean an EGR Valve
The EGR valve is the heart of the emissions system on an engine. EGR is an acronym for Exhaust Gas Recirculation, and that is exactly what it does. This wonderful...
How to Replace an EVP Shut Off Solenoid
An EGR valve is essential to the EGR system in your vehicle. For this valve to work, the EVP shut off solenoid must monitor its position and function.
How to Replace an EVP Position Sensor
The EGR valve is monitored by a valve position sensor. This sensor helps your car's EGR system to run more efficiently and better control emissions.
How to Replace an Exhaust Gas Recirculation (EGR) Tube
The EGR valve is connected to an EGR pipe, which helps distribute molecules through your vehicle’s EGR system. A bad pipe leads to performance issues.
How to Replace an Exhaust Gas Recirculation (EGR) Cooler
Exhaust gas recirculation (EGR) coolers lower the temperature of the exhaust gas before it enters the car engine. EGR coolers are mainly for diesel.
How to Replace an Exhaust Gas Recirculation (EGR) Temperature Sensor
Exhaust gas recirculation (EGR) temperature sensors monitor the EGR cooler's operation. One is on the exhaust manifold and one is near the EGR valve.
How to Buy a Good Quality Exhaust Gas Recirculation (EGR) Tube
Exhaust gas recirculation tubes (EGR tubes) are responsible for moving a very small amount of gas from the exhaust manifold to the intake manifold in order to help reduce emissions of nitrous...
How to Buy a Good Quality Exhaust Gas Recirculation (EGR) Valve
The exhaust gas recirculation valve (EGR valve) serves to dramatically reduce the emissions that are key contributors to pollution in the air. While EGR systems were not routinely added to engines until...

Check the engine for a vacuum leak and see if the valve on the brake booster is leaking. Also check the EGR (Exhaust Gas Recirculation) is stuck on all the time. A vacuum leak or the EGR being stuck on...
Question
Want to pass emissions testing, but I have a P0400 code for my vehicle. 2000 Nissan Altima
Hi there - the P0400 code you have suggests a problem with the Exhaust Gas Recirculation system of your car. Given your mileage, this malfunction could be a clogged EGR valve or tube, solenoid or leaking exhaust gas tube. I...
Question
Massive hesitation between 1-2 shifting and nearly dies occassionally at stop.
Hi there. It seems that the EGR (Exhaust Gas Recirculation) Valve is stuck and not allowing the engine to run good causing the engine to hesitate, especially when shifting. Take the EGR off and clean it. Then put it back...
Question
My check engine light is on and I have a code P0401 in my 2010 Chrysler Town & Country
Hello. Typically when you get this code it is because you have low flow in the EGR system. If the EGR valve is good and if the tube is clear then you either have a clog in the intake manifold...
Question
2009 Ford Escape has a code P0400 even after EGR valve replacement
If your test results for KD5 and KD7 are accurate, there is a short between the PCM and EGR stepper motor. Your readings indicate both a short to ground and power, so my guess is that the four wires inside...

Question
Difference between egr valve and egr valve pressure sensor
Hello, thank you for writing in. The EGR valve (exhaust gas recirculation valve) takes exhaust emissions and recirculates it back into the air intake as to lower toxic emission levels. The EGR valve itself is pressure regulated, and needs some...
Question
Egr valve insufficient flow
Insufficient EGR flow is probably not the cause of the rough or low idle and thus is just a coincidental fault. You should repair it and perhaps first, just to be absolutely sure, but rough idle is more likely due...
Question
Why is it still misfiring?
Hi there. Check the Exhaust Gas Recirculation valve on the engine. It seems to be sticking on when the engine is running at low idle and causing a misfire as the old exhaust that is burnt is reentering the engine....
Question
Have code P0174, did smoke test smoke comes out EGR valve. Does that mean it's bad? 2004 Ford Ranger
Hi there - smoke coming out of the EGR valve simply means the valve is either leaking, or stuck in the "open" position. The P0174 code indicates a "lean" condition too much air/not enough fuel on the bank of cylinders...
