The Function of the EGR Valve on a Honda Civic

What does a Honda EGR valve do?

Now what an EGR valve basically is well today’s internal combustion engines employ a procedure called exhaust gas recirculation. Or EGR to cut down on the amount of nitrogen oxides emitted into the

Can I still drive my car with a bad EGR valve?

Technically you can drive without a working EGR valve.
The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn’t working quite right, more toxic gases will be released into the air. For this reason, we don’t recommend driving without a working EGR valve for too long.

What will happens if EGR valve is blocked?

A faulty EGR can result in excessive carbon/soot at the turbine end of the turbo charger. This could cause the VNT mechanism to become clogged and stick which in many cases will cause engine management lights to appears along with reduced performance known as “limp mode”.

How do I know if my EGR valve needs replacing?

And hesitation. And in some cases you might even have a misfire. Especially under hard loads. And sharp accelerations.

Can I drive with a blocked EGR?

Is it safe to drive with a faulty EGR valve? It might be safe for a short period, but prolonged driving with a faulty EGR valve can impact engine performance and emissions. It’s best to address the issue promptly.

What happens when the EGR valve goes 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.

What is the most common causes of EGR failure?

However, the single biggest cause of failure is the buildup of carbon particles from the exhaust gases along the EGR and intake system passages. Over time this will clog tubes, exhaust gas channels and eventually the valve’s plunger mechanism, causing it to either stick open or close.

Is it OK to drive with a bad EGR?

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.
