You were probably correct about the first two codes.

P0406 is most likely an egr valve.

P0868 is for low line pressure. It is usually caused by low fluid. It was likely fixed by the trans service you did.

The P1521 was caused by putting 5w40 in it. That code is for incorrect engine oil type. Is that what you usually use? Is this your first oil change with this truck? 5w20 is the recommended engine oil weight.

5w40 works just fine in the Hemi engine. I've been running it for years. There might be a TSB for PCM software updates that cover fixing that code. It's a stupid code really.

if the truck has mds, it is more finicky regarding oil unlike the 03's-05's.

What year is your hemi? There is no tsb. If the guy is trying to diagnose a code for incorrect oil type, the first step would be to put in the correct oil viscosity. Seems pretty simple.

yes guys i intend to stick to 5w30 next time that code and the egr code i don't really care about them

what makes me sleepless is the P0868 low line pressure code i did already change the transmission oil and filter 3 weeks ago but the code has just come back 2 days ago >>>> really dunno what i should do next ????


i'm going to dodge service center and see what they gonna say about that

and for sure i will keep you informed .

but if already someone have some kind of suggestion or information about that matter you so welcome..

sorry i know my English aint that perfect.

TSB for 2006, not sure if it applies to 2008 or not:

Thank You xtremewlr

i will ask them in the garage to do this update

any idea about the low line pressure code

I would start by making sure the trans fluid isn't low. See if after the truck sits and is cold if it doesn't want to move when you put it in gear. You might have trans fluid draining back out of the torque converter into the pan.

It does not apply to 2008.

clear the codes and when you start it in the mourning let it idle for 10 to 20 seconds before shifting, my 05 daytona will throw the the code if i rush it, its been that way since new, at 800 miles dealer did the filter swap, same problem, i have since done 3 trans service's and now have 83,000 miles shifts great, just have patience on cold startup and it should be fine
