Changed the egr valve but still get the code p0406 what could it be now
Did someone check the power from the PCM (power control module) or maybe the pipe from the intake to the egr could have a small leak.

P406 is a EGR code, EGR will also cause a knocking/ pinging sound when there bad. Very common problem. The position sensor inside the valve goes bad. Your going to have to replace the whole EGR valve and it can put out variety of codes from P0401 to P0406. The new valve will solve the problem and easy to replace, you can pick one up at Auto Zone and they can give you the step by step instructions to replacing the EGR with common tools. Good luck and hope this helps.

Hi there good luck with it ,,,, this is what I did. It was going to take a week to order one from Schucks auto so I took matters into my own hand. I removed the valve from the car lots of posts on how to do this I then pried up the three double tabs with a screw driver marked the cap location to the body and carefully removed the top plastic cap. inside you will find two spade lug style connectors and the top of the plunger. this is a solenoid style egr. If you can push down on the solenoid and it returns easily great. the inside of the cap has a small plunger that is the sensor part. the solenoid should read about 7 to 8 ohms resistance at the spade lugs. the sensor should read around 3 thousand ohms and one of the terminals should vary between 3 thousand and 0 ish. If thats all good the problem you may have had is the electrical connection between the spade lug connectors and the two leads that point straight down from the black plastic cap. Give the spade lug connector a gentle squeeze with a pair of pliers and use a bit of electrical grease and carefully press the cap back down into position with the pins inserted into spade lug slots. reinstall and celebrate.
