You need to look into the wires at athe position sensor and if all look good then the position sensor for the EGR can then be assumed as the fault. Afte repairs the Code will need to be cleared by removeing the negative battery cable.

Had code po404 so changed the sensor, now code po406 is showing up and car idles extremely high. What is causing this and how to I fix it?


Opp's

OBD Codes have nothing to do with changing parts

Codes are Parameters that are out of range

You check for codes & use them to diagnose the
system that set them & component test to find a problem

So--- Google your codes & read up

Aside from the P0406 code, I'm also getting code P1561. Are they related and what can I do to fix it? I have 2006 Dodge Ram 1500.


The po406 is an egr code which is common for a bad egr valve, but check your wiring and check for plugged port or carbon lodged in valve, as far as the p1561 this is not a good code, this must of been gotten with a genric scan tool, i would fix the po406 and then reset the computer readiness monitors and drive it and go from there. hope this helps, good luck

What will be wrong if I got code p0406 and p 404


both codes po406 and po404 refer to a fault in the EGR system
Po404 > Exhaust Gas Recirculation Circuit Range/Performance not within proper range.
Po406> Exhaust Gas Recirculation Sensor A Circuit High (meaning the circuit is open or disconnected)
Without actualy checking the voltages (wiring)
Replace the EGR valve
clear codes
test drive
