What Does the P0404 Code Mean? Diagnostic Trouble Code (DTC) P0404 stands for Exhaust Gas Recirculation Circuit Range/Performance Problem. It is a generic OBD trouble code that activates if the powertrain control module (PCM) detects erratic Exhaust Gas Recirculation (EGR) valve performance.

How much does it cost to replace the EGR valve?

The average cost for EGR valve replacement is between $332 and $413. Labor costs are estimated between $81 and $103 while parts are priced between $251 and $311. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

How do I fix code P0400?

What repairs can fix the P0400 code?

  1. Replacing the EGR valve.
  2. Replacing a broken vacuum line to the EGR valve.
  3. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it.
  4. Cleaning carbon out of EGR tubes to intake manifold.

Can you drive with a blocked EGR valve?

Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.

Where is the exhaust gas recirculation sensor?

The EGR temperature sensor is usually mounted in the exhaust manifold or mounted near the EGR valve.

What does exhaust gas recirculation control circuit mean?

The exhaust gas recirculation (EGR) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. On GM vehicles (such as a 2016 Silverado), the P0403 code is stored when: The ECM/PCM detects an open circuit condition of an EGR motor control circuit for greater than 3 seconds.

What damage can a faulty EGR valve cause?

One of the most significant parts of the EGR system is the EGR solenoid. A faulty EGR valve can damage the EGR solenoid which can, in turn, cause performance issues for the engine. The engine check light would turn on then, and then the engine might knock and ping.

How do I unblock my EGR valve?

EGR Valve Cleaning

  1. Spray carbon deposits with EGR-valve or carburetor cleaner. …
  2. Use a dull scraper and a pipe cleaning brush to scrub carbon buildup. …
  3. To deal with rock-hard buildup, leave the valve soaking in the cleaning solution for a few minutes. …
  4. Repeat step 3 to fight stubborn carbon deposits.

How do you clean an EGR valve without removing it?

How To Clean an EGR Valve Without Removing It

  1. Gather the needed cleaning supplies.
  2. Locate the EGR Valve.
  3. Gain access to the EGR Valve.
  4. Start the vehicle and rev it to 2000 RPMs.
  5. Spray half of the cleaning solution (250ml)
  6. Reinstall the EGR valve cover.
  7. Scan the vehicle for error codes.

How do I know if my EGR valve is stuck open?

Open Position: Rough idling and problems with acceleration are the two most common indicators that the EGR valve is stuck open. The truck might also stall excessively. When the EGR valve is stuck open, all of the exhaust gas cycle back into the chamber, meaning there’s not enough oxygen for a combustion to take place.

Can the EGR valve cause starting problems?

The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases, into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting.

How do you clean an EGR valve?

The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases, into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting.

What is EGR valve position sensor?

The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.

Where is the EGR valve located?

The EGR valve is usually located near or attached to the intake manifold, with a tube running to the exhaust manifold. There should also be a vacuum or electrical connector (or both) running to the valve which will need to be detached.

What is EGR a control circuit range performance?

Exhaust Gas Recirculation Circuit Range/Performance

Using the information from the EGR, the power control module (PCM) controls the valve to regulate the exhaust fumes going through the cylinders. The valves will open or close to increase or reduce the exhaust fumes flow depending on how your engine runs.

Is it worth replacing EGR valve?

On older cars operated by engine vacuum, the EGR valve diaphragm can deteriorate and leak, causing a rough idle and a check engine light. In that case, the valve should be replaced. Also, over time the valve can accumulate carbon buildup and stick open, causing a rough running engine.

Can I replace my EGR valve myself?

In most models, replacing an exhaust gas recirculation (EGR) valve is not difficult. You can do it in your garage in about an hour or two, depending on your particular system, using some common tools and a good solvent like carburetor cleaner.

How long do EGR valves last?

An average car’s EGR valve has a lifespan of approximately 10 years in service. Proper maintenance of the valve is a must if you want to avoid any performance related issues on your car. If you notice a smell of fuel that comes out from under the hood or rough idling, then it might be time to replace the valve.

Can I drive with P0400 code?

It really depends on the cause. If the code P0400 is caused by some minor issue like a faulty EGR temperature sensor and the EGR system works properly, there should be no problem driving.

What can cause a P0400 code?

What are the Possible Causes of the P0400 Code?

  • Faulty EGR valve.
  • Clogged EGR passage.
  • Disconnected or damaged vacuum lines.
  • Faulty EGR-related sensor (e.g., EGR temperature sensor, EGR pressure sensor, etc.)
  • Issues with the EGR control circuit, such as damaged wires or poor connections.

What causes exhaust gas recirculation flow?

One of the most common culprits here has to do with your car’s air filter. An overly dirty filter restricts airflow into your engine, often leading to rich fuel conditions. By replacing your air filter, you should not only restore an ideal air-fuel ratio, but also the problems associated with excessive EGR system flow.
