hey guys, I'm a newb on here... so please forgive my ignorance if this has been discussed in length previously

I have an 05 diesel ram, 4X4 5inch Flo-Pro exhaust, auto trans with an Edge Juice with Attitude....

now for the problems....
it threw a P2146 the other day.... and it hasn't quite run right since, I had noticed that it wasn't boosting as hard before it threw the code, and now it will ONLY slowly climb to 39, not SPIKE to 45 like it did when I first got the box....
the code only stayed lit for less than 24 hours, called the dealership, and they said that since the light went away, there was no use in them lookin it over....

I"m curious if the WG is leaking boost now, since its seen high psi a 'few' times now..... or if there is something else wrong....

thanx in advance

 

come on guys, anyone got a clue?

I had the DTC cleared today at AutoZone... and it runs better, but still doesn't spike like it used to..... so I dunno whats goin on

help me out

 

I would start by looking at the boots and clamps around the aftercooler, airhorn and turbo. Could be leaking.
But the code is strange, P2146 is Fuel Injector Group 1 Supply Voltage Circuit.
Does the truck idle fine, no missing?

idles GREAT, unless I rush and fire it up before the light goes off.....
I"ll check the boost hoses tomorrow.... just to make sure they're not leakin on me....

I LOVE the way this thing runs on warm days..

thanx for the help

 

I just read the J/A manual. Since the connectors on the J/A piggybacks the injectors I would check each one of those, add a little dialectic grease to the female side connectors. My guess there's a intermittent issue in this area that cause the P2146 code.

have you pulled the codes on your truck (personly ) see what it has thrown ect....... after they cleared the codes? by checking to see if the intercooler pipes are leaking they have to be underpressure (boosted) onless if way broke or came off then the truck wouldn't even run .

 

yea, after it was cleared, I did the onboard diagnostics trick, and it showed nothing.... so it was cleared, and did help it run a tid bit bettter

I was planning to get up under it today and tighten all the boost pipes, but the weather decided to drop 20degrees from yesterday, so I don't plan on freezin my *** off for it.....
