How to Clear Service Emission System Duramax

If your Service Emission System Duramax is giving you trouble, there are a few things you can do to clear it. First, check all of the connections and make sure they are secure. Next, clean the sensors and the MAF sensor.

Finally, reset the system by disconnecting the battery for 30 minutes.

  • Park your vehicle on a level surface and turn off the engine
  • Disconnect the negative battery cable
  • Remove the EGR valve from the exhaust manifold using an appropriate socket or wrench
  • Clean the EGR valve with carburetor cleaner and a brush
  • Inspect the EGR valve for damage and replace it if necessary
  • Reinstall the EGR valve and reconnect the negative battery cable

Most drivers never think about their car’s emissions system until there’s a problem. But this system is actually critical to your vehicle’s performance and longevity. Here’s everything you need to know about how your car’s emission control system works.

Your car’s emission control system is made up of several different parts, all working together to reduce the harmful pollutants emitted by your vehicle. The most important part of the system is the catalytic converter. This device uses a chemical reaction to convert dangerous gases like carbon monoxide and hydrocarbons into harmless water vapor and carbon dioxide.

The other parts of your emission control system work to prevent these harmful gases from ever reaching the catalytic converter in the first place. For example, your engine’s air intake filter keeps harmful particles from getting into the combustion chamber where they can be emitted through the exhaust. And your fuel injection system ensures that only clean, properly-burned fuel enters the engine.

Regular maintenance is key to keeping your emission control system functioning properly. That means changing your air filter regularly, using quality gasoline, and getting regular tune-ups according to your manufacturer’s recommendations. Neglecting these simple steps can lead to big problems down the road – including costly repairs or even total failure of the emission control system.

What Does It Mean When It Says Service Emissions System?

When a car’s service emissions system light comes on, it means that the vehicle’s emission control system is not functioning properly. The light may come on due to a problem with the catalytic converter, oxygen sensor, or other emission control device. If the light comes on, it is important to have the car checked by a mechanic as soon as possible to avoid damaging the engine or causing excessive pollution.

How Do You Clear Codes on a Duramax?

In order to clear codes on a Duramax, you will need to use a code reader or scanner. Once you have located the code, simply press the button on the device that says “Clear” or “Erase.” If the code does not clear, then it is likely that it is a permanent error code and will need to be addressed by a mechanic.

How Do You Reset the Check Engine Light on a 2006 Duramax?

If your 2006 Duramax is displaying a check engine light, there are a few things you can do to reset it. First, try disconnecting the battery for 30 seconds. This will sometimes cause the light to reset itself.

If that doesn’t work, you’ll need to take it to a mechanic to have the code read and then reset.


If your truck is a 2004.5-2005 model year and it has the 6.6L Duramax LB7 engine, then it’s time to perform the service emission system (SES) procedure. This simple maintenance task will save you money and headaches down the road. The SES light comes on when there is a problem with the exhaust gas recirculation (EGR) system or the diesel particulate filter (DPF).

The light will either be solid or flashing, and if it’s flashing, that means the problem is more urgent. If you ignore the light, eventually your truck will go into limp mode and can do serious damage to the engine. The SES procedure involves opening up the DPF and cleaning out all of the soot that has accumulated over time.

It’s a messy job, but it’s not difficult to do. You’ll need to purchase a DPF cleaning kit from your local auto parts store or online. Make sure you get one that’s specifically for your truck model year and engine type.

Once you have the kit, follow these steps: 1) Park your truck in a well-ventilated area and put on safety glasses and gloves before starting work. 2) Remove the negative battery cable from your truck to prevent any electrical shocks while working on live wires.

3) Locate the DPF under your truck near the exhaust pipe (it looks like a large metal canister). There are two hoses connected to it – one coming from the EGR valve and one going to the muffler/tailpipe assembly. Use clamps or pliers to loosen both hose connections at their base (but don’t remove them completely).

Have a drain pan handy to catch any diesel fuel that may drip out when you disconnect these hoses later on in this process..” Assuming you want me to summarise what needs doing:

The Service Emission System needs performing every now an again as specified by Chevrolet – especially if living in dusty conditions as this affects how often it’ll need doing .It takes around 2 hours should no issues arise during disassembly/reassembly such as rusted bolts etc,. You’ll need specific equipment which can be found in an automotive store or easily enough online . Safety first of course so make sure work space is well ventilated an wear gloves/eye protection .
