How can I replace the EGR tube in my car?
Scan the computer system in the car. Check all vacuum related hoses to EGR valve. Test EGR transducer. Verify the EGR port is not clogged. Remove and replace the EGR valve and gasket.
How does the exhaust gas recirculation ( EGR ) valve work?
The EGR valve takes a portion of the gas that your engine is excreting, and recirculates it through the intake manifold. The intake manifold then sends the gas back to the engine, where it is used again to power your vehicle. The tube is a key part of the EGR valve, and when the tube fails, the EGR valve will fail to do its job.
When do you Know Your EGR valve needs to be replaced?
One of the earliest signs that your EGR valve needs to be checked is the frequency of your Check Engine Light coming on. Do not ignore this signal. Be proactive and check what could possibly be wrong with your vehicle. You will also notice excess exhaust emissions of your car. If you take an emission test in this condition, you will surely fail.
What causes an EGR valve to stick open?
• Poor performance at low speeds—EGR flow should only occur at cruising speeds and light load. If the valve is sticking open due to carbon buildup, the exhaust flow reduces the amount of fuel added to the cylinder and results in poor performance and lower MPG.

What should I do if my EGR valve is clogged?

Is there a problem with my EGR system?
I have a problem with my EGR system, I have a newly purchased 1997 Subaru Outback limited, High miles 175K, 5-speed, 2.5L, 4 Cyl. Started off I would get the Check engine light with a code P0400 stating EGR flow problem. System consists of BPT (Back Pressure Transducer), Control Solenoid, and EGR valve. I have done all the tests in the manual.
How often should you change the EGR valve?
Clear the trouble codes and test for proper operation of EGR valve. It is a good idea to get an air induction (carbon cleaning) service performed every 50,000 miles. This should clean out any sludge or carbon build-up in the air intake system. Always keep up with the regular oil changes; it will help prevent sludge build-up in the engine.
