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....
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...
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...
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...
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...
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...
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...
Code P0400 does not necessarily mean that there is something wrong with the EGR valve itself. The only way to condemn the EGR valve is to directly test it. In particular Code P0400 includes a circumstance where the EGR passages...
P0406 involves the EGR system but that may or may not be the only factor causing your rough running condition. Typically, P0406 will set if you have a failed EGR valve, excessive carbon buildup, an open or short in the...
In order to isolate the cause of the misfire you will need to do an engine compression and leakdown test to make sure the compression is good and no valves are burned. If compression test is good on all cylinders...
Hello, thank you for writing in. Unfortunately, the picture you tried to add did not come through. If you are trying to find a particular part, you will want to determine what it does first. Since you are dealing with...
Hello, thank you for writing in. For exact specifications on tools needed and a step by step procedure, you will need to access a service manual for the vehicle. Typically you would expect to use a 12 mm socket or...
Hello. I would need to know which EGR code you are getting in order to be able to precisely tell you what may be going on. Most of the time if replacing the EGR valve does not solve the problem...
Hi there. The EGR (exhaust gas reciculation) Valve needs to removed and cleaned out. If the engine continues to not drive faster than 40 mph, then I recommend replacing the EGR valve. If you need further assistance with your vehicle...
Check to see if any diagnostic trouble codes have been stored. If the engine runs (actually "runs", even momentarily, as opposed to stumbles) when you directly introduce fuel, that means there is something wrong with either the fuel system and/or...
In order to replace the EGR tube it can be replaced in less than an hour. The tube may not be the only issue though and the intake manifold EGR ports may be clogged and need the intake manifold to...
Either the EGR (Exhaust Gas Recirculation) valve is stuck open or is closed and not opening. First try removing the EGR valve and cleaning it out. Then see if the engine light goes out and the engine runs good. If...
Either the EGR (Exhaust Gas Recirculation) valve is stuck in the open position or is closed and not opening. First try removing the EGR valve and cleaning it out. Then see if the engine light goes out after cleaning the...
You may be having an issue with the EGR control solenoid sticking or not venting the EGR system and causing the problem. I would suggest to disconnect the solenoid and road test to see if problem goes away? If it...
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...
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...
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....
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...
Hi there. Check the Idle Air Control valve and see if it is plugged or not working. The IAC valve controls the engine idle and when the vehicle is at a stop the idle can drop and cause the engine...
Either the EGR - Exhaust Gas Recirculation - has been plugged up or the MAF - Mass Air Flow - sensor is dirty or damaged. Try removing the vacuum line to the EGR and test driving the vehicle with the...
