Running 50 mph truck just cut off? code on dash P0340.. I replaced cam sensor still no start.. engine cranks but no start.. anybody deal with this before, local garage suggested engine replacement?? need help. 5.7 hemi eng

 

Local shop suggested engine replacement huh? And I guess they want to sell it to you and install it for you too huh?

IDK bout the code off hand but if you didnt sling a rod through the block then keep your current engine and find another shop.

 

Sounds like the shop was hopping you were stupid and they could make a quick buck.

 

Check ur wiring make sure a rat didnt chew it up. And it could also be the crankshaft position sensor or the pcm.

 

Nope no rod thru the block... going to try a new PCM next will update when that is installed.

 

Zteeters,

There was a TSB regarding P0340 that involved a PCM flash. I am posting it below in case it could help with your issue.

NUMBER: 18-014-09 REV. A
GROUP: Vehicle Performance
DATE: November 6, 2009

SUBJECT:
FLASH: ESP System May Prematurely Activate Momentarily When Negotiating A Curve
Or MIL Illumination Due To Diagnostic Trouble Code P0340, P0344 or P0116
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new software.
MODELS:
2004 - **2007** (HB) Durango
**2007 (HG) Aspen**
**2007 (DR) Ram Truck
2005 - **2007** (WK) Grand Cherokee
2005 - **2006** (WH) Grand Cherokee (International Markets)
2006 - **2007** (XK) Commander
2006 - **2007** (XH) Commander (International Markets)
2004 - 2006 (KJ) Liberty
NOTE: **This bulletin applies to the HB/HG/WK/WH/XK/XH/KJ vehicles equipped
with a 3.7L, 4.7L or 5.7L engine (sales code EKG, EVA, EVD, EZB or EZA).**
NOTE: **This bulletin applies to the DR vehicles equipped with a 5.7L engine (sales
code EZB).**
SYMPTOM/CONDITION:
The customer may experience a premature and momentary activation of the Electronic
Stability Program (ESP) system. The premature activation of the ESP system may or may
not be accompanied with the illumination of the ESP indicator lamp located in the
instrument cluster. The customer may experience the momentary ESP system activation
on a “clover leaf” type turn, at speeds of approximately 25 to 40 MPH (40 to 64 KPH). This
could also be described as a lack of throttle response or hesitation. Driving over speed
bumps at a slight angle can also cause the same ESP event accompanied by lack of
throttle response. The customer may also complain of low idle speed.
The customer may also experience MIL for one of the following Diagnostic Trouble Code:
i. P0340 - Camshaft Position Sensor Circuit - Bank 1 Sensor 1
ii. P0344 - Camshaft Position Sensor Intermittent - Bank 1 Sensor 1
iii. P0116 - Engine Coolant Temperature Sensor Performance

 

Thanks for the info Chris...I will check into that.
In the mean time. Can anyone tell me if I can use ecm part# 05094893AB... My part# is 05094402AI I have an 2007 Ram 1500 4X4 5.7L Hemi..

 

Well No luck replaced the ECM/PCM with a brand new one.. still cranks but no start.

 

Well spent most of the afternoon pulling the front of the engine apart..... What I found was disturbing to say the least.... Timing chain is in pieces...Chrysler says
" Sorry about your luck" it is no longer under warranty.. 53000 miles chain should not have broke in my opinion. but hey who am I ?

To see the damage click the link, I could not post the image>?

Crazy thought. Bad transponder in your key??
If you use a key without the transponder, it'll turn over. But will not start.
