Answers :

P1409 is a fault code fo the stepper motor in the EGR-usually they get dirty from carbon and you need to remove the EGR and clean it with throttle body cleaner. \015\012\015\012\015\012This \015\012 egr (exhaust gas recirculation) stepper motor code is \015\012 best checked by physically having a look at the bottom \015\012 of the egr stepper motor. When the vehicle engine has \015\012 a lot of mileage, a carbon build up will occur at the \015\012 pintle rod at the bottom of the motor and make the exhaust \015\012 gas passage difficult causing the code. When removed, \015\012 the carbon can be clean and pintle rod freed up so that \015\012 it moves. Yours is stuck open, causing poor idle since it is introducing exhaust gas into the intake manifold during idle, which if operating properly it will not do at all.
