egr valve pintle position circuit

My SES light came on and I got it checked. The code was p1406 which is "the egr pintle position was 10% of the expected position" the guy at auto zone was saying it is likely a short or pinch in the circuit and to check the wires from the egr to the computer (because I just replaced the egr valve around the start of the summer)

My questions:
Is it possible that the egr valve is already clogged and a cleaning would fix it?

I know very little about auto electronics and electronics in general so can anyone give me info on how to check the connection and find/fix my problem in the wiring? Thanks guys!

There is an EGR pintle relearn procedure you can do.
I don't remember the exact steps.

I dont know about the procedure, though Im sure Navy is right. I do know that there is a separate code for a clog in the EGR system. I forget what it is but I know I have it.

Sounds like it reset itself.

Cool! Side note: im going code reader shopping tonight. I dont know much about them other than they are for sale for a wide range of prices. Can anyone tell me a good code reader that I can grow into and what features are useful to have in one?

You want one you can update via a USB cable and that can also clear codes.

This is the one that I have. Its easy to use and plenty of nice features. I didn't pay that much though. I might have a 20% off coupon code though.
