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.

Nissan codes po400 and po328


EGR inop, check the BPTV hose. this valve is located next to the EGR and the hose to check is a small vacuum type hose under the valve going to a metal pipe. This is not vacuum hose (vacuum hose will burn) so you will have to get it from Nissan if it is faulty. Also check to see it the EGR moves when revving engine,if it does the EGR ports are plugged and need to be clean (not for the novice)

1998 nissan frontier xe 4 cyl auto misfire cyl #2 engine vibrates like a bad sparkplug when driving


To review - - do you know for a fact the distributor is firing that cylinder? And do you have power and a ground pulse for that injector ?
You say no vac leak, but have you done a compression test on all cylinders ? Is it possible the egr valve is leaking and affecting that cylinder ?

# 2 cylinder misfire no rough idle excelarets fine no loss of power i changed # 2 injector roter plugs wires egr turned light off it came back on after a frew miles


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!

Check engine soon light on. EGR code


Before you unpack the EGR you might be able to save the old one by cleaning it an then collect a refund. The purpose of the EGR is to supply a measure of exhaust gas to the intake mix so that the charge delivered to the engine is reduced in oxygen. This reduces the ignition temperature and prevent nitrous oxide formation in the exhaust. The EGR valve has two ports in it side by side. The one to the exhaust is gated by the valve and the other is connected to the intake. The valve is pulled open by a diaphragm acted on by a vacuum line from the intake manifold. The EGR valve is often monitored and regulated by differential pressure feedback exhaust DPFE sensor that lies upstream on the vacuum line leading to the EGR. If this DPFE fails it will report the same EGR light. Remove your EGR valve and plug the open EGR intake port on the manifold with a cloth and reconnect the vacuum line to the EGR valve. Start the car and now watch the action of the EGR valve. It should seen to open and close depending on engine demand. If it looks badly coked, spray it liberally with carb choke cleaner and wipe with a cloth until everything is polished metal. If the EGR looks good and is obviously working take a long look at the DPFE sensor; DPFE sensors have a reputation for failing many more times more often than the EGR valves they monitor.

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.
