Trouble Code 1406

Can anyone tell me what a code 1406 means, or possible causes. I have a 1997 Chevy C1500.

P1406 is reference to EGR position. I just had this on my bosses 97 Suburban. Either your EGR valve is clogged or bad. Take it off and use some carb cleaner and clean it out real good. Put it back on, clear the codes and see what happens. If it comes back you likely have to replace the EGR Valve itslef.
Hope this is helpful to ya,
