Why do I need to replace the EGR valve on my Nissan Frontier?
The EGR valve is responsible for taking the spent emissions and recycling them through the engine to be burnt a second time, limiting the exhaust fumes that are sent out of the tailpipe. Occasionally, the EGR valve will need to be replaced due to the emissions clogging up the valve and resulting in reduced gas mileage and a poor running engine.
What happens when you have a bad EGR valve?
This, in turn, reduces the car’s performance and increases pollution as well. When there is a problem with the EGR valve, the check engine light or EPC (VW) light may appear on your dashboard. The two main issues EGR valves face are that, either the valve stays open or it shuts completely.
How much does it cost to replace an EGR valve?
For newbies, we recommend that you take your car to an auto-specialist who can diagnose the problem effectively and provide you with a solution. On average, the EGR valve replacement should cost somewhere between $200 to $900. The component itself costs around $70 to $490. It’s often the repair time that is expensive.
What can I use to clean an EGR valve?
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
What’s the code for an EGR valve throw?
What code will an EGR valve throw have? The P0401 trouble code is related to your car’s exhaust gas recirculation (EGR) system, which controls an engine and reduces emissions. Suppose a computer-controlled valve gives a certain amount of gases back into your engine to be burnt with the air-fuel mixture.
Why is my EGR valve not working properly?
If there is a fault in the EGR system, it can cause the EGR not to function properly. Your vehicle’s EGR valve can be faulty due to the accumulation of carbon deposits in its internal surface, pitting, burnt valve, a damaged diaphragm for a vacuum-type EGR valve, or distortion of the valve seat. This problem can also have the following causes:

What should resistance reading be for EGR valve?
For an electric EGR valve, you need to have a multimeter; this device will be used to do a resistance reading, referred to as an ‘ohms test.’ Once connected, you should see a reading of about 20 to 24 ohms. You can check the repair manual of your vehicle for this.
