You have two options to fix this error code. One, obviously, you can replace the EGR valve. If you do this, just reset the codes and you should be good to go. Two, you can remove the EGR valve and clean the carbon build up out of it. You can do this with throttle body cleaner and just make sure to let it dry out before you put it back on. You need to make sure that the valve (diaphram) is moving freely after you clean it. If it isn't, you are going to need to replace the EGR valve. Let me know if you have any further questions. Thanks for rating my response and for using FixYa!

Either clean with carburetor cleaner or replace with a known good one or a new one.You have to remove it to clean the carbon from the inside of the EGR valve.Sometimes this works,the cleaning part that is Repalcing with new is always best.

You can try removing the EGR valve first and cleaning the carbon deposit with carburetor cleaner. Once it's clean,dry, and inspected for any damages. Re-installed the EGR, double check the wire harness and look for any damages. If the codes don't clear after the third start up then it's time to replace the EGR valve. 
Good luck and hope this helps. Keep me posted, be glad to answer any questions you may have.

PO122 and PO405 engine codes


Code 122 is for a low signal coming from the TPS. Since you have replaced the sensor, the problem may be in the wiring harness. The signal would need to be checked.
Code 405 is also a low signal coming from the EGR valve. Same thing, you need to check the signal with a scanner or volt meter.
And when the computer is not getting an acceptable reading from the TPS it uses a known good signal to bypass the sensor which will cause the idle speed and shifting problems. The computer does not know when you open the throttle.

Erroe code po405 on my car


Hello.
The error code PO405 = EGR, ( Exhaust Gas Recirculation ), sensor A circuit low input.

What the EGR does;
EGR = Exhaust Gas Recirculation system
Recycles small amounts of exhaust gas from exhaust system, 8 to 10 %, and mixes it with intake manifold air going into the combustion chambers. The addition of this inert, or non-combustable exhaust gas limits the peak combustion temperatures to a range that is below 2,500 degrees F, where the formation of nitrogen oxide, ( NOx ), is known to occur.

Here's a picture of an EGR valve to help you locate yoursem1cl_1.jpg
You may find that you just have a lose hose, or you may have a small vacuum leak.

I hope this helps you.

2001 Isuzu Trooper PO405 code


The throttle body is coated with a sludge resistant material. If you cleaned it all out you are actually hurting your engines performance, because the throttle body resists sludge which in turn protects your throttle plate and bore. You may want to check your egr vacuum regulator, for the cause of your problem.

1998 Cavalier 2.2L I'm pulling codes of PO404 and PO405 The First says EGR Flow CKT Range/Perf The second is a Circuit Low Input for EGR Sensor A. PO405 is a constant code while 404 came up only once, but...


In the top picture you can see egr adapter, three bolts, the egr valve mounts to adapter. Hope the picture gives you some orientation? You can see the 5 wire connector and wire colors. The bottom picture should be the egr valve.
