Last night, I tested the van for over an hour and it didn't shutdown; that's not unusual, given the intermittent nature of this problem. However, for the first time since I started testing it in late June, the check engine light came on. I cycled the ignition switch on - off - on - off - on and read the codes: 12, 27, 55.
 
Code 12 means the 12V battery monitor was disconnected sometime in the past 50 key-on cycles. Code 27 is an injector circuit failure. These were not what I expected after seeing the captured coil driver waveforms.
 
I drove the van to a friend's shop this afternoon where we tried to induce a PCM failure by applying vibration to the PCM mounting points, the PCM connector's mounting bolt, and the firewall next to the PCM mounts using a steel rod inserted into an air tool; i.e., basically a small jackhammer. The van kept running but the scope triggered so I need to look at that data.
 
I'm now wondering if this could be a PCM ground problem. I need to study the grounds to the PCM, especially any splices.

I have a 2007 ram 1500. the gascap warning came on, the service center replaced the cap and reset the light, it came back on later that day, the service center said there was a charcoal filter that needed to be replaced, they said there was not a sensor on it but that was the only other thing it could be, any ideas?

I looked at my alldatadiy.com account for my 94 van and couldn't find any diagnostic aids for the fuel cap. Therefore, I'm afraid I can't help much because of the difference in the age of our vehicles.
 
You could replace the sensor that's providing the signal that results in the failure code. Wouldn't that be a pressure sensor? There might be a fuel-line pressure sensor and also a fuel tank pressure or vacuum sensor but I'm just guessing.

Hi To all the dodge ram guys with passenger side window problem, after six months of trouble shooting the window problem I have fix. It works for me so give it a try, place wedge between the connector plug and the wire harness blue mash snap that holds the connector in the switch plug. I used a large cotter key and behold the window is working and the back windows work again. It must be such a small no contact between the plug and switch blades this is what worked for me. Try it and see what happens. Any ? email me 100nitrodragracingfrontiernet.net put something about windows in Ur email so I know its real.
 
                                       Good luck KB500

A guess: Maybe there's a failue in a warning input to the computer(s). For example, maybe it thinks one of the seat belts should be buckled but isn't. In that case, you might have a bad seat switch, the switch that senses presence of a person.
 
If you've checked the owner's manual and checked with the dealer, try a general web search.
 
Other options: Find a Chilton's (or similar) maintenance manual for your van at your local library or buy one at an auto parts store or online. You could also subscribe for maintenance data for your vehicle at http://www.alldatadiy.com .

Thanks for the response,
 
Web search brought me hear and I was hoping to find out the problem online without bringing it in to the dealer.
 
What's odd about the beeps is that they are long 4 second beeps with a 2-3 second pause in between not like the short ding ding of a seat belt not on.
 
If anyone has had this same issue I would love to hear how you resolved it.
 
Thanks again.

Does the beeping occur while you have your foot on the brake? If so, check for a burnt tail light bulb.

Nope that's not it actually just had the truck safety'd so all lights turn signals etc are working so i'm still puzzled.
 
When I figure this out i'll be sure to post back here what the problem was.
 
Cheers
