What should the p0406 EGR sensor reading be?
There is a feedback sensor on most EGR valves that informs the computer of the actual EGR position. This sensor usually ranges between .4 and 5 volts If this EGR position sensor has an abnormally high reading for too long, this code may set. Symptoms of a P0406 DTC may include:
Where does the wiring harness start at the EGR valve?
Being that the wiring harness that goes to the EGR valve is by the hot engine it has a higher propensity to fail than other wiring in the vehicle, it is often the problem. Find the wiring harness where it starts at the EGR valve.
What happens if you have a bad EGR valve?
When the valve is opened, exhaust gases are allowed through the vehicle’s EGR system to help control vehicle emissions. When the EGR valve has an issue, it can cause problems with the flow and operation of the EGR system, which can lead to increased emissions and performance issues. Usually, a bad or failing EGR valve will produce any these 4…
Where is the EGR valve on a Chrysler?
Open the hood and locate the EGR valve on the upper area of the engine, next to the valve cover. The valve resembles a thick mushroom with a round, metal hat.
Where is the vacuum hose on a Chrysler Town and Country?
Unplug the vacuum hose from the top of the EGR transducer. This is a disc-shaped, plastic component attached to the EGR valve through a rubber hose and a metal line.
