The EGR (Exhaust Gas Recirculation) valve in Toyota vehicles is an important component that helps reduce tailpipe emissions and lower combustion temperatures inside the engine. It works by recirculating a portion of the exhaust gas back into the engine, which can result in a reduction of available oxygen for combustion.
Toyota EGR valves have a reputation for being unreliable and prone to failure, especially if they are not regularly serviced or maintained. Over time, EGR valves can become clogged with oil and soot, which can further reduce engine performance. If the EGR valve is not functioning correctly, it can lead to issues such as decreased power and acceleration, rough idle, and the engine management light coming on.
If a fault code related to the exhaust gas recirculation is displayed, it is likely that the EGR valve will need to be either cleaned or replaced . Cleaning the EGR valve is generally a cheaper option compared to replacement. Regular servicing and maintenance, including inspecting the EGR valve for signs of wear or damage, can help prevent issues with the EGR system.
The location of the EGR valve can vary depending on the specific Toyota model. For example, in a Toyota Yaris, the EGR valve can be found on the front of the engine on the piping in front of the valve cover. If you are unsure about the location of the EGR valve in your Toyota vehicle, it is recommended to consult your local Toyota Centre or refer to the vehicle’s repair information.

Should EGR be removed?
EGR Systems Have Improved But The Bad Reputation Remains
What some people don’t realize is that yes, deleting an EGR system can help prevent some expensive repairs. But they can also cause major problems in other parts of your engine.
What does EGR do to your car?
EGR systems recycle a portion of the exhaust gas back into the combustion chamber, where it combines with fresh intake air. This lowers the amount of Oxygen and increases the water vapour content to the combustion mixture which reduces the peak combustion temperature.
Is EGR expensive to fix?
How much does it cost to replace an EGR valve? The average cost of replacing an EGR valve is £265, with prices ranging from £150 and £650. If the faulty EGR valve has caused increased emissions and overheating there is a possibility that it could have caused damage to associated components.
Will EGR throw a code?
However, some older EGR systems are completely vacuum/mechanical and have no feedback. So the only symptom you would get might be a poor idle, or even an engine that dies at idle. In modern cars plugged EGR or Stuck open EGR can throw a code.
What is the EGR system on a Toyota?
What is an exhaust gas recirculation (EGR) valve? The EGR valve in your Toyota is fitted within the exhaust system and allows some of the gases produced during the combustion process to be re-burnt within the combustion chamber for a second and more effective time.
How do I know if my EGR is failing?
Let’s start with from the driver’s point of view the most noticeable. And worrying symptom of them all engine. Issues if the EGR valve is stuck open for any reason you might be experiencing a variety
Does EGR reduce engine life?
Once carbon builds up in your engine through the EGR, it causes more damage and reduces its lifespan. However, an EGR delete would reduce the carbon buildup output, extend your engine’s lifespan, and save future maintenance and repair costs.
Is it OK to drive with a bad EGR?
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.
What is the life expectancy of EGR?
Generally, an EGR valve has a lifespan of about 10 years or 100,000 miles, whichever comes first. Regular cleaning every 50,000 miles or so will extend that lifespan.
What happens if your EGR is bad?
A malfunctioning EGR valve can lead to a noticeable decline in engine performance. You may experience a rough idle, hesitation, or stalling when starting your vehicle. Acceleration may feel sluggish, or you may notice a lack of power when driving uphill. Increased fuel consumption.
