How do you change the EGR valve on a Dodge Ram?

Push the electrical plug back into the EGR valve plug, and lock the plug with the red tab. For the 4.7/3.7, you will need to re-install the resonator box. To clear the check engine light, disconnect the negative battery cable with a 10mm wrench for five minutes. Figure 6. The 4.7/3.7’s new EGR valve has been installed.

Where is the EGR valve located on a Honda Accord?

There are a total of four bolts: one is on the connector attached to the valve. The 4.7/3.7’s EGR valve is located on the rear of the driver’s side cylinder head, making it very hard to change without removing the resonator box. Refer to Step 1 of the Related Article: How to Replace Ignition Coils and Spark Plugs for this procedure.

Where is the EGR mating surface on a Dodge Ram?

Figure 5. The cylinder head EGR mating surface on the 4.7/3.7 engine. Slide the two bolts with 10mm heads through the valve, and then place the gasket over the bolts. Now guide the valve down into position against the cylinder head/intake manifold.

Where is the intake valve on a Dodge Ram?

The valve is bolted to the intake manifold/cylinder head and a metal hose connects it to the exhaust manifold/intake manifold. An electrical connector sends and receives signals to the PCM (powertrain control module) to control the valves movement for optimal emissions.

Where is the EGR valve located on a Dodge Ram?

The 4.7/3.7’s EGR valve is located on the rear of the driver’s side cylinder head, making it very hard to change without removing the resonator box. Refer to Step 1 of the Related Article: How to Replace Ignition Coils and Spark Plugs for this procedure.

What’s the code for an EGR valve throw?

What code will an EGR valve throw have? The P0401 trouble code is related to your car’s exhaust gas recirculation (EGR) system, which controls an engine and reduces emissions. Suppose a computer-controlled valve gives a certain amount of gases back into your engine to be burnt with the air-fuel mixture.

Why is my EGR valve not working properly?

If there is a fault in the EGR system, it can cause the EGR not to function properly. Your vehicle’s EGR valve can be faulty due to the accumulation of carbon deposits in its internal surface, pitting, burnt valve, a damaged diaphragm for a vacuum-type EGR valve, or distortion of the valve seat. This problem can also have the following causes:

What is the code for a bad EGR valve?

The odometer will then flash any codes the computer is giving. In this case my odometer showed P0406. I then went to Google, looked up the code and found it was the code for a bad EGR Valve. There are many ways to deal with a bad EGR valve found on Google, some say to clean it, some say to replace it.

How do you install a check engine light on a Dodge Ram?

Install the hose to the valve by hand first, and then tighten the bolts until snug. Push the electrical plug back into the EGR valve plug, and lock the plug with the red tab. For the 4.7/3.7, you will need to re-install the resonator box. To clear the check engine light, disconnect the negative battery cable with a 10mm wrench for five minutes.

Why is the EGR on my Hemi not working?

This EGR is a robust design and really shouldn’t have this kind of problem – ever! ( see next) THE mechanical problem – The design of the EGR allows the exhaust gases to put “pressure ” on the seal that should keep them from laying down carbon deposits on the stem of the valve.

What are the symptoms of a bad EGR valve?

When there is a problem with the EGR Valve, the check engine light or EPC(VW) light may occur on your dashboard. The two main issues EGR valves face are that, either the valve stays open or it shuts completely. Here are some common symptoms you will notice if you have a bad EGR valve.

How much does it cost to replace an EGR valve?

For newbies, we recommend that you take your car to an auto-specialist who can diagnose the problem effectively and provide you with a solution. On average, the EGR valve replacement should cost somewhere between $200 to $900. The component itself costs around $70 to $490. It’s often the repair time that is expensive.

What are the different types of EGR valves?

This helps to ensure the car maintains fuel efficiency and emits fewer emissions. There are two types of EGR valves; a vacuum-operated and an electronically controlled EGR valve. A vacuum-operated EGR valve is usually only found in older vehicles. It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open.

What happens when you have a bad EGR valve?

The engine will have a rough idle when the EGR valve is faulty because it will remain in an open or closed position. This implies that too few or too many exhaust gases are entering the chamber, and this is why the engine is idling.

What can I use to clean an EGR valve?

This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
