Caravan/Voyager :: 2007 - P1607 Internal Shutdown Timer Rationality Condition
Dec 26, 2012
My caravan is doing this thing lately (cold weather) where i start it and when i hear it start i let off the key and it dies instantly (like It fires for an 1/8 second). Ive had it go as bad as 7 tries before it stays running. after it does get running it runs perfectly. The most recent time it threw a code of "p1607 internal shutdown timer rationality condition"
other noted issue is that the power steering pump squalls really bad when its under about 45 degrees until it warms up, fluid level is fine. I think the fluid is gelling up causing alot of friction. I dont know if this added friction upon cold start could lead to the engine dying right away.
I have also heard that there are some idle sensors of some sort that can cause this dying on startup condition.

My 2007 Dodge Caravan has only one working headlight, the passenger side does not work on high or low beams.
At this time I'm wondering if the problem is in the headlight plug itself, because there are no other complications other than the passenger side not working.
The light did work at first on high beams but now not at all. replacing bulbs makes no difference. There is some brown discoloring on the white strip on the plug face, nothing like this on the driver side.
Also hoping that the problem is not the relay or front control module.

2002 Chrysler Voyager, 3.3L V6, 133K miles.
I'm experiencing an intermittent total electrical shutdown. Driving at any speed, electrical system cuts out - lights, radio, gauges, motor - everything shuts down for a period of 3-4 seconds, then power is restored. Transmission that has disengaged during shutdown takes a few more seconds to re-engage. This can happen 15-20 times during a 25 mile trip or not at all. Last evening a 25 mile trip to destination w/ no problems. On the return, 6-7 shutdowns in the first few miles, then nary an issue. This morning, in pulling around a block to unload some cargo, 2 cutouts. I do not have to touch the key for the restart.
I have cleaned battery terminals & connectors w/ baking soda, scrubbed them w/ battery brush, coated w/ DiElectric grease, run an auxiliary ground, had the battery load tested (good for 700 cold cranking amps), and taken to the local mechanic who spent a few hours and 3 cruises w/ an analyzer hooked up. Not to worry, no problems manifest when van was w/ mechanic. BTW, no fault codes thrown, no "Check Engine" light appearing. Ignition switch tested as OK.

My mechanic has diagnosed a trouble code P0601 (Internal Control Memory Fault) on my 2002 Dodge Grand Caravan. He and I feel the car is running fine. Do I need to get the PCM replaced (as I've been reading online) or can I drive it as is? We don't have emissions checks.

We just purchased a 2012 Grand Caravan and was wondering where to get a key and program it. I know the key will be an arm and a leg if i get it from the dealer. Is there a tutorial that tells how to program it as well?

2006 Caravan. Heat comes and goes every minute or so. Also noticed the temp gauge goes from normal operating range to cold and back again frequently. Hasn't overheated. Does that sound like a thermostat problem?

On my 2005 3.3L Grand Caravan the ABS light keeping coming on. I inspected the sensors for the front and used my compressor to give them a quick puff of air to get rid of dust. The light went off for about 5 days. Now it is back on.
How does one read ABS codes? If I knew for sure that the problem is a speed sensor and which one I could clean or replace the faulty sensor.
If I clean to sensor are there any special precautions I need to take? As far as I could see they didn't look very dirty.

What am i missing i have a terrible clunk in the front end when i hit bumps. I thought it was the struts and mounting plates so they are new . no change Stabilizer links were tight but i replaced them as well. Everything else seems tight but the noise has not changed with any of the above mentioned repairs.

I'm having trouble with my 96' 3.0L, its kind of crazy its intermittent and while driving the engines surges one or twice and then dies... when I try to crank it up again cranks but don't starts if I try again it wont even crank ( no starter winding up ) what I noticed is that is I'm driving when it dies my check engine light disappears for a while and if I connect my OBD 2 reader does not link up with the ECU if I wait a while and I crank it up again its starts and the while cranking up I can hear a bang noise from the engine compartment drives side and then after a couple of minutes dies again...

I have a 2006 Grand Caravan 3.8 that just stalled at a set of lights yesterday and have had it towed back to the shop here. I turns over and starts briefly then will die and then just turn over strongly. I cleaned the throttle body and IAC but this did not work. I connected fuel pressure tester and have no pressure when turn key on or turn it over.
The fuse and relay check out ok, so I'm thinking bad or clogged fuel pump.
I have a 2004 Caravan out back that I have used for other small parts to interchange before and was wondering whether or not the fuel pumps between these two are compatible. Be a lot of work to pull the one off the one in the yard, only to find out its not going to fit.

142k, having some problems lately, the van won't accelerate now and again, moreso when the engine isn't up to temp, but lately it's gotten more and more prevalent. I have done some recent and needed maintenance in hopes of fixing the issue, but to no avail so far. I've replaced the plugs and wires, air and fuel filters, and both upper and lower O2 sensors (first replaced the upper with a Bosch, almost immediately had problems with P0134 code, so instead went with a Denso, hasn't come back yet). I checked fuel pressure, 60 psi sitting in the shop, the cat doesn't seem to be clogged, and it idles fine all day long.
Problem resembles running out of fuel, or more maybe like I'm letting off the gas, but my cheap scanner says the TPS is working fine, and I was watching the TPS percentage as I was driving it was reading normally. As I'm accelerating slowly from a stop, it'll start to cut out around 30 mph, but speed doesn't seem to matter, if I accelerate sharply it just bogs and slows down, if it does shift up a gear, the rpms will jump to about 5k, then slowly decrease even if I've got my foot on the floor. I keep coming back to the fuel pump, but I don't have a long enough hose to have it connected while test driving. Considering removing the hood so I can prop the gauge up so I can see it while driving. I am getting a P0132 code now, but I'm more concerned with the accelerating issue.

Intermittently the ABS Light is coming on. 84,000 miles.
Brakes have been changed once, 10,000 miles ago.
Minor clunk sound when light is on.
Light goes off after van has set, brakes work fine at that point.

I've been fighting with these vehicle for months, and I've only been able to narrow down the list of possible issues. Tried replacing the ignition switch, battery terminals and cables, starter, and even a PCM since according to the dealership it was bad. I've checked all the fuses and relays, and they're all ok.
I'm getting fuel and spark, but no crank from the starter. The voltage going to the hot post on the starter is 12.7, but the voltage from the igniton wire is only reading around .5-.6, fluctuating a bit. Before I spend the money on taking it to a mechanic I wanted to know what your opinions were on what the next step is. I know a bit about electrical systems in cars but I'm no expert.

Someone put sugar in my gas tank so I had it worked on at the Dodge place they replaced my fuel pump..fuel filter cleaned the tank..flushed the lines cleaned my injectors and replaced the plugs..I went to pick it up I barely made it a mile down the road I had no power and a lady flagged me down to tell me to pull over because I had sparks coming from the bottom of my van I looked under the van and the catalytic converter was red like hit coals the Dodge place is telling me its my flex plate? I think they are misdiagnosing the issue because before the sugar issue I had no problems with my van?

2005 town country, on interstate, cruise a 85, drives smooth, then vibrates pretty good, it will vibrate for a few seconds then smooth, then vibrate. the vibration is felt everywhere, steering wheel, seats, even the outside mirrors vibrate, at 60 we don't feel it much, at 45 nothing. we notice when coming to a slow stop or just scooting up in traffic that it seems to have a little wobble to it too.
All brakes and rotors and all motor and transmission mounts are new, struts, strut mounts, sway bar, sway bar end links and bushings are new, have had it checked and nobody can find anything wrong. no clunking noise moving the tires left to right and up and down. alignment is perfect. the tires are crappy but am thinking if it was a tire problem it would vibrate all the time and not on and off. its never been wrecked either. it is a 3.8, front and rear sway bars, long wheel base, nivomat rear.
Wheel bearings? I don't know but would think they'd make noise moving the tires back and forth and side to side. and hear no clunking over bumps at any speed.

I start my van and open the hood to check Coolant and I notice gas spilling out engine and running down the side close to my power steering pump. So I stop the vehicle and notice gas sprayed on different parts by the back spark plugs and a little area by sensor.

Changed oil on the 2014 grand caravan, replaced the filter. afterwards the oil light comes on at low rpm goes out when u accelerate, and the engine light is on. Took it to autozone, it is saying, that the oil sensor switch is stuck.

2001 T&C with 3.3, 4speed tranny and 128K miles.
Here's an interesting one: This morning I went went to get gas and no problems getting to the gas station. I pull out of the gas station and get to the first light, again no problem. Light turns green, I go and the tranny shifts from 1st to..... nothing! Just like I slipped it into neutral. I coasted into a parking lot, moved the gear selector from Park to R to D to L, and nothing.
I put it in Park and shut off the engine, then restart and shift into drive and it goes into gear! I start to drive away and when it's time to shift, it goes from 1st to.... nothing again! Once again none of the gears work, until I shut the engine off and restart.
After I restarted the engine I shifted to L and drove home in 1st gear keeping an eye on the tach so I wouldn't exceed 3500 RPM. Got home with no problem.
So, to recap, when it goes to shift up from 1st it goes into nothing. Just like neutral. No check engine light, not "limp mode". If I shut off the engine and restart, it'll go into 1st, and if I keep it in L so it won't try to shift up, it'll drive all the way home in 1st. Reverse doesn't work no matter what I try.
Some background: I changed the tranny fluid and filter 2 years ago at around 90K. fluid level is good. It did rain hard last night, conicidence? The engine compartment is dry.
I think it is safe to rule out a mechanical problem, this seems to be electrical and we can probably rule out the tranny range sensor since it keeps it in 1st when I have it in L and the backup lights come on when I put it in R.

My boss bought me a van, so we could start a detailing business, anyways, we got the van for . Not bad inside, and ran ok, boss didnt notice it wasnt shifting i guess. So it went straight to the shop, got new brakes, rotors, belts, plugs, and oil change. Boss did transmission flush on it to see if it would work, he said it shifted into second for him, but when i was driving home. It would not shift outta first gear.Check engine light is on. It is an automatic. I dont know what to do now,
