Back in the Stone Age, we used to pull it, do a scrub-and-rinse with a little gasoline, and pop it back in. BUT if yours has an electric lead/wire, then you probably need a new one.

How do you clean a PO400 code on a nissan frontier 2002

That's going to be an EGR code. More than likely your EGR valve is either clogged with carbon buildup or it stopped working altogether.
Another culprit could be the EGR solonoid but most likely its the valve itself.

Troubleshooting Nissan frontier egr code

Replace the EGR valve. EGR is Exhaust Gas Recirculation valve and you'll lose a lot of power if the valve is bad.

# 2 cylinder misfire i changed # 2 injector plugs wires roter egr light is still on does the vent breather have any thing to do with this problem nissan frontier 2004 xe

Is this the 2.4L? If so, I bet the Exhaust Gas Recirculation (EGR) valve passages are clogged. Likely has 3 of 4 EGR ports clogged, sending all EGR flow to the #2 cylinder. Check if it still has 8mm plugs in each runner for EGR transition passages. If so, remove those plugs to clean the EGR passages.
Hope this helps. Good luck!

sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.
