i have 04.5 dodge diesel 4x4, and i had the short block rebuilt in the spring and have had nothing but trouble with it. now these engine codes came on yesterday,p0514, p0541 and p2127. also when in Drive it seems like it is in 2nd. 75km/ph at 2000 rpm. all in the last day or so. any ideas. thanx

 

If you are asking what the codes are

po514-battery temp. sensor circuit range /performance

po541-intake heater A circuit low

p2127-throttle/pedal position sensor/switch e circuit low


low / bad battery mabe ??

 

Any idea what those codes really mean? Also i noticed my oil pressure was a little higher than normal. Is there a web site to find out different engine codes?

 

Please fill out your sig so we know what mods you have in the truck...

I'll look up those codes. It sounds like you may be having some ground/old battery problems. Some weird crap happens when those batteries start going. I have an 04.5, and the batteries started taking a poo recently.

 

Thanx Mark, i'll fill that out right away. i'ts a 04.5. It seems one thing after another goes wrong with this truck.My wifes got a 2007 chevy Duramax diesel and trying to persuade me to change teams , but i'v been a loyal moper guy for 23 years. So i'm not ready to switch yet.

Welcome to the DTR, BTW.

When ever you start fooling with big stuff like engine overhaul, you can have some problems like this. If the person that replaced your SB did not tighten grounds or clean contacts, or if he left the door/hood open before he disconnected the batteries, and ran them dead and re-charged them, this could cause a lot of it. How long did the truck sit when he did this? Did it rain? Corrosion, right there.

Go pull both your batteries out of your truck, put one of momma's new D-max batteries in there, see what happens.

 

Now that's alot of info !!

 

It is the dealer troubleshooting matrix. Some of the things you can't do with out their equipment, but some of it is useful.

Ask, you shall receive!

 

U DA MAN !

 

Mark were the hec did you find all of this? the p2127 code [pedalvalidation switch] would that be why the truck feels like it is in 2nd gear when it is in drive? Thanks again.

 

It could be. Remember, on our trucks, almost everything is electronically controlled. Sometimes, when you have tranny/shifting problems like this, signs point to valve body/line pressure problems, or bands being stretched.

With all of this stuff happening at once, I would be looking for what caused every thing to go Tango Uniform at the same time.

You said you are at 2k RPM's at 70? That's normal for a 48re and 3.73 rear end ratio. Listen for the shifts and count them.

Where do you live?

 

Nah... Just tryin to help the Diesel world out!

 

I have a dealer pub...

Anytime.

I'd really look at some batteries before you start tearing stuff up.

 

I had the rebuild done when i was working up in northern bc,and then about a month later it was making a hell of ticking in the moter.So i had to load it up on a flat bed and take it back to the shop were i had the work done[750 miles away] The problem the was when they sleaved the #1 cylinder the sleave broke of on the bottom. So they redid the moter and they started having problems with the wiring, computer, #6 ingecter,fuel pump on the moter. in all it was a $22,000 bill and all most a divorce.Thanks for the help Mark
