How to Clean an Electronic EGR Check Valve

The EGR valve recirculates exhaust gases back into the combustion chamber to optimize fuel delivery and make your ride more efficient. It also reduces the amount of pollutants emitted by the vehicle. If the EGR valve sticks or malfunctions, the air/fuel mixture will be affected, causing the engine valves to knock against the piston heads or the vehicle to idle rough. When you notice that there's something wrong with the EGR valve, inspect it right away. Sometimes, all you need is to clean the EGR valve to restore its functions. Here are the steps in cleaning an electronic EGR valve:

Difficulty level: Moderate

Things you'll need:

  • Service manual
  • Pipe cleaner, toothbrush, or small-bristled brush
  • Carburetor cleaner
  • Wrenches
  • Sockets
  • Ratchet
  • Screwdriver
  • Replacement mounting gasket

Step 1: To avoid short circuit, disengage the negative battery cable from the battery. This way, you can be sure that no current will flow through the system while you're cleaning the EGR valve.

Step 2: Disconnect and remove the sensors, hoses, and electrical connections you may come across with while doing the task.

Step 3: Loosen and remove the bolts so you can take off the EGR valve and gasket.

Step 4: Carefully check the gasket and hoses to know if they can be reused or if they already need replacement.

Step 5: Spray a carburetor cleaner into the valve and hoses. With a brush, eliminate the carbon buildup from the hoses; use a pintle in cleaning small holes. Avoid spraying the cleaner into the sensors or electrical connections.

Step 6: Put the EGR valve, gasket, and bolts back in place and reconnect the sensors and electrical connections.

Step 7: Engage the negative battery terminal.

Check if your newly cleaned EGR valve is functioning well; ask someone to rev the engine while you are checking for the plunger movement. The plunger must be able to open and close. If it does, that means the EGR valve is working well. If it doesn't, then the valve already needs a replacement.
