Question about 2005 Dodge Caravan

1 Answer

PO406 Code I have a 2005 Dodge Caravan SE. The engine light came on and I took it to get checked...the computer found it had a PO406 Code. Which means that the ECM has detected the EGR position senosr voltage was too high. I am low in funds due to lossing my job...my question is, How much would it cost me to have it fixed? Does the valve need to be replaced and how much would it cost? Can I keep driving it for short trips to the store? Thank You, ALicia of Houston, TX

Egr code d 0406


CODE PO406 EGR POSITION SENSOR CIRCUIT HIGH INPUT.

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

2005 dodge caravan, with po406 code, what do i need to do


This code refers to the EGR valve. I have an idea for you to try that just might save you a repair bill. Go to napa, autozone wherever you buy parts and get a bottle of Seafoam. Put Half in the gas tank. For the other half, pull the vacuum line from the brake booster and get a skinny funnel. Pour the remain fluid slowly into the vacuum line. This line goes to your motor not the brakes just to clear that up. Have a friend hold the RPM's at 2,000 and start pouring. Your van is going to smoke white for a few minutes. Drive it for about 10-15 miles. Come home and reset the computer by removing the negative terminal for 2 minutes. Start the engine and see if the code is gone. This works 8 out of 10 times. Hope this helps.

2005 Dodge Grand Caravan. Check engine light on displaying PO0406 any ideas? Code came up by cycling key on and off 3 times.


the PO406 code is the EGR position sensor.
I have heard tho that DMX corp had some issues with this code in the past where basically it was just tossing false codes. But they also did have a higher fail rate on them during 05-07, so you may have to replace it anyways.

Error Codes P0700 and P0605


0605 is for an Internal Control Module Read Only Memory (ROM) Error. This is typical of a malfunctioning computer. If the computer is bad, your retrieved codes are probably wrong anyway. May need to replace computer, drive, then see if if your check engine light returns.

The check engine light on means there is a code stored in the ECM. You will have to have the OBD II system scanned and cleared. The other problem is probably just a blown fuse. If you need more help get back to me.
