yes the EGR control your nox output. by re diverting the exhaust gas's back into the combustion chamber, you want to make sure the egr valve still works by putting vacuum pressure on the egr vacuum line. and feel if the diaphragm moves. if it doesn't move then the egr is bad. My vehicle is also throwing the same code and found out the wiring harness that controls the vacuum solenoid and has an intermittent fault. you might also want to check you vacuum lines that run to the egr valve and make sure they dont have a leak.

That means there's still a problem. This means the computer didn't immediately see the issue, but discovered it when it tried to actuate the valve or after the system warmed up.

 

The FSM has a diagnostic procedure starting on page 93 of the EF&EC section for diagnosing your code. :clickdalink:
