my Nissan frontier with the 2.4 motor is showing a code of P1402, just wondering what that might be?

Suspect EGR valve or part of the EGR system...maybe transducer. How does the vehicle idle?

Sounds like the EGR may not be closing at idle due to dirty EGR valve or defective EGR or improper signal from the ECM to the EGR.

Most can be cleaned if that is all it is. I would try that first. If defective, obviously it will need to be replaced.
