FD 35 Isuzu Engine 4LE2 Turbo.

I can't find much on the code P0409 EGR Sensor Malfunction.
I am asking if anyone has run into this problem.
The Trucks Starts and Runs Cold. Once Warm and Shut off, No restart until Cold Again.
Only code stored is P0409.
Unfortunately, Isuzu Support is lacking. I don't want to start throwing parts at it.

The black box flight recorder was invented by Australian scientist David Warren in the mid-1950s. While initially met with indifference in Australia, his invention gained international recognition, particularly in the UK, and is now a mandatory piece of safety equipment on all commercial aircraft.
