This is my first dodge truck...was hoping that I wouldn't have any problems so soon. Today I stopped to get gas...my next stop was just a few miles up the road. When I went back to get in my truck it took awhile to get it started. Now it idles rough and the computer must have taken over...no trottle response at all. There are 4 codes..P0129, P0340,P0652 and P2127. I was hoping someone might know what these codes mean. Called the dealer and sounded like I knew more that the service writer. Any help would be appreciated!

Ok, here's your codes
p0129--Barometric Pressure Out of Range

p0340--Camshaft Position Sensor

p0652--Sensor Reference Voltage 2 Low

p2127--Accelerater Pedal Position Sensor 2 Circuit Low
p2127--PPS 2 Voltage Too Low

I think the first thing I would check is your battery connections. Clean them up good, then make sure they are properly tightened.
When you lift the the battery connection, that will reset the computer. Just to make sure that it fully resets, while the battery terminals are disconnected, turn on the headlights.

If that doesn't do it, I'd suggest taking it to a dealer. It should still be under warranty.

 

Also, since you just filled up check the gas cap, that can cause rough idle and no power. Easiest way to tell if it is the cap is to take it off and give it try without.

 

BTW Somewhere here on the forum, you can download the Factory Service Manual for your truck. I purchased one when I bought mine, so I ended up paying for it, but either way, it is out there. And as you've found out, sooner or later, you'll need it. These new Dodges have several computers in them for all sorts of stuff that help them GO FAST

 

Thanks Guys...appreciate the help!

Most likely your gas cap. It's a common enough post around here. Tighten it lots, don't be afraid of the clicks.

 

I checked the gas cap and the grounds to the block, frame and body. I loosened them, made sure they looked clean and snugged them back up. At first I thought of the fuel, since I had just stopped, but when it was throwing all those codes...I tried disconnecting the battery. After Gone Fishin's post, I tried the battery again and then the head lights...I didn't think about if there might have been a capacitor that might store current. I'm sure that it is something simple...just frustrating. I've owned one dodge before an 88' daytona. I had nothing but trouble. Then fell in love with the Ram and bought one, even though everyone around here drives a chevy or ford. The really bad part is all the crap I'll have to put up with from my friends...that told me not to buy it. But, sometimes it's best to stand alone and be different! haha Again...to everyone that responded...Thanks.

I'll pass along what the dealer finds.

Highly unlikely something failed on the truck. Very likley that you got a tank full of water or diesel and codes are caused by the continuous cranking with no start.

Sorry to hear about that problem...I've got 38k on my '04 without a hiccup yet. You should still be under the 7/70 warranty, so just take it in and let the dealer figure it out. Sounds like you've tried all the obvious stuff, and that many codes can drive you nuts sorting them out. Let us know what you find out.

Use this link if you need to download your service manual. Good luck.

 

Thought I'd pass it along...just in case it could help someone else later.

Just got my truck back and as it turned out it wasn't bad fuel...the dealer replaced the MAP sensor.

Hopefully it was just one of those things and I won't have anymore issues for a long while.
