Question about 2002 Nissan Frontier Crew Cab
SERVICE ENG SOON CODE P0402
Sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.

If too much EGR flow exists due to an EGRC-BPT valve malfunction, off idle engine roughness will increase.
If the roughness is large, then the vacuum to the EGR valve is interrupted through the EGRC-solenoid valve.
If the engine roughness is reduced at that time, the EGRC-BPT valve malfunction is indicated.
