Caravan/Voyager :: 2000 - RPMs Will Jump Up 400 And Go Back While Driving
Feb 5, 2015
My wife has a 2000 t&c with 150k on it its a fwd with 3.8 and about a month ago while driving we noticed the rpms will jump up 400 and go back, with cruise control on or off being held at a consistent speed. and about for days ago it started shifting late. Still has all gears fluid looks o.k. and is full no check engine light .
I am hearing transmission solenoid, tps sensor, input sensor, output sensor, tcm, iac, map, or egr are all possibilities or a rebuild . Or simple as a flush.. tonight i went out n started it it idles around 800 tried to hold it at 1200 and it would for a second and drop back to 800 with accelerator being slightly held. Not sure if related. Just observed it..

2007 Grand Caravan SXT, 86K Miles
Factory Radio Clock, AM/FM, CD and Tape Player.
Radio and Clock looses power and completely shuts off and will not turn back on while driving. Miles driven does not seem to be consistent.
All other Electrical seems to work fine, overhead console, Wipers, Blower, Turn Signals, Head Lights, Instrument Panel all seems fine.
When car is shut off, Blower continues to run for a few seconds and then stops.
When car is restarted Radio/Clock magically comes back, clock is reset to 12:00 and radio is on AM.
Get some funny flashing of Idiot lights on cluster that to my recolection is not normal behavior. Once while my wife was driving it the Vehicle Theft Alarm Light came on when she started it up and it stayed on until she stopped and then started it back up when she left the store she was at. That has only happened once.
I checked the Battery Voltage while running and stopped and all seems normal. The Battery was new this December. I also checked fuses and there are none that are blown.

My GC is overheating. Started as occasionally but now increasing in frequency. I find it will being to overheat after driving on the interstate for half hour or so but I can "calm" it back down but turning on the heat. I've replaced the following:
1. coolant (no drips or leaks nor am I losing coolant over time)
2. thermostat (twice)
3. temperature sensor
4. serpentine belt and tensioner
5. radiator (last summer)
6. water pump (last winter)
I notice the fans run more often than they should. For example, after a 10 minute ride to work in the morning,. I notice the fans are running as I pull into my parking space.

1st problem is shifting from 1st to 2nd and sometimes from 2nd to 3rd though, 2nd to 3rd is not as bad as from 1st to 2nd. It stumbles and gets really bad if I don't let up on the gas. After the initial shudder it will go into 2nd just fine. I also have to gun the gas a little bit when I first start the car, or it will just sit there and idle and never go into gear.
2nd and more annoying is that it stalls after driving around a bit. It happens on freeway or city. It doesn't stutter or anything the rpm's drop to 0 and it just stalls and won't start up for a 5 - 10 minutes or so.
Codes pulled are P0731, & P0736. The transmission was replaced about 2 years ago with a refurbished one. Could it be going out again already? The guy at Autozone suggested replacing the TSS (Transmission Speed Sensor?) to see if that was the problem. I have not done this yet, but plan to.

My check engine light came on today and while driving, the idle (RPM's) were very high. At about 80KMs, it was about 3500 and when I accelerated, the engine would race along with the RPMs. While stopped, idling seems fine. I couldn't get over 80KMs/Hr without the idle going too high.
What it could be? Haven't had time to check codes as it is long weekend and garages are now closed till tuesday.

A few weeks ago I took my 03 Caravan to a shop and they said my alternator was fine, but the Wal*Mart battery (which I assume is a piece of rubbish) reads a bit low. When the temperatures are about 25 Fahrenheit or below the engine will sputter a bit usually at stop lights and the headlights will dim then go back to normal brightness a few times.
Now that the temperatures are in the 40s-50s I am still having this problem, but not as pronounced and sometimes it happens rather randomly. There is now another problem to go along with it. If I have the steering wheel turned hard while backing up and am not pressing the accelerator I have almost had Edward (my name for the Caravan) stall on me instead of just sputtering. Sometimes I feel like the engine is surging a wee bit as I drive down the road if I have just let off the accelerator. In general the RPM seems a bit erratic at times.
The fuel economy is the same as ever, the belts are all new over the past year, spark plugs, and all that. Recently replaced the vacuum plugs where the cruise control would go as well.

So the other day I was driving to my storage locker about 30 miles away. All of a sudden my rpms would shoot up to 2000 rpms then back down to 1500 . Slowly they would go up higher every time. On my way back I was about 2 miles away and I lost 3rd and 4th a presume. I would be going 20-25 and it felt like it would be shifting up to third but would shift down to 2nd running 3500 rpms. I had to go 20 the rest of the time. Finally I got home and realized my dipstick tube wasn't in the tranny and must have lost oil. So I got it back in and added more. Thought it was the filter and oil so dropped the pan and replaced it. Still nothing.

97 2.4 caravan dies while driving. Its been going on for awhile, coded at o'riellys and autozone several times. It started with having the camshaft and crankshaft replaced. Problem solved for a few days but it always returned.It would restart a few minutes later then it got worse. I called it the 30 mile van 'cause that's all it would go before dying or not restarting immediately.
Go to the grocery store, have to wait another 30 minutes to go home. Then it started only going a few blocks before shutting down while driving. I replaced the o2 sensor, the shutoff and fuel pump relays and finally took it to a shop that engine coded it. On their advice, they said the codes were all over, jumping everywhere, we replaced the ECM. It went 5 hours driving great then died and immediately restarted. Again no dash codes.

I have a 2003 Dodge Grand Caravan and while I was driving it stopped on me. It will turn on but once you put it in gear it will turn off and wont turn back on. I have replaced the fuel filter and fuel pump.

I had to replace my swaybar links on my T&C due to it not passing state safety inspection. There was also some random noise that occasionally occurred on bumps. The tech said the "book" said to replace the strut and strut mounts but he could not see anything wrong. After replacing the swaybar links, there is now clunking while driving. I thought it was a lack of grease in the links but I greased them and while it got a little better...it still happens.

I just replaced the transmission in my 2000 3.3L Grand Voyager and now it won't start. It started fine when I drove it into the shop. The battery is good, the cables are ok. The starter worked good up to this point. I checked all the connections to make sure they are tight. I replaced the transmission because reverse went out.
When I turn on the key, the shift letters (PND32) appear on the instrument panel, but the little circle that shows what gear it is in does not appear. When you turn the key to the run position, the circle should be around the P to show it is in park.
When I turn the key to start, nothing happens. No clicks or anything. The next thing I am going to do is see if there is power to the starter when the key is in the start position. Where to start looking?

I am about 600 miles from home and when I was driving on the intertsate the battery light came on. I am in northern Maine where there are long stretches of nothing. I checked to make sure the belt was on and it runs fine. When I got to civilization I shut it off and it started and the light went out. Now I don't know if I should trust it or try and get to a dealer 70 miles away?

My wife has been driving our 98 Dodge Grand Caravan the last couple of days and while she is driving the Tachometer and Speedometer will drop to 0. This does not affect the performance of the engine or anything else. Runs and drives "perfect" (or at least for its age and mileage). The dash seems to "reset" when she parks and turns off the ignition then restarts it.

My van just started to have this issue today with jerking real hard like its dropping a couple of gears while going between 50-60mph. It is a 2000 with the flex fuel 3.3L 4 speed auto.When this happens the spedo will go from 55mph to 40 instantly while keeping a steady speed and it feels like the tranny is going to rip right out. This will happen every 5 to 10 min but go back to normal driving after 3 sec and has not popped any codes. It runs like a top and all fluids are at the correct levels. I have to commute 50 miles a day to work so i really need to figure this out!!!

Drivers side not bowing hot air? We changed the blower motor and the resister on the passenger side. We hadn't tried to use the heat until last night when we needed the defrost and that's when we realized only heat on passenger side.

First, sometimes the engine began shuts off. When the drive up to the traffic lights. When sharply throw gas pedal. When the engine speed is less than 2000. If you release the gas pedal, you will see that the tachometer needle drops below 500 rpm and the engine stalls. This happened happened two or three days all right. And sometimes a day, 3-4 times shuts off. Then ringing under the hood.
Was the flywheel. I remove the transmission and replace the flywheel. More repair parking brake pedal. So it turns analyzed under the panel. I have a new problem. After repair. I driving my Dodge week. And once. After an overnight stay the machine, on morning the engine not start. I checked the spark. The spark is. I removed the fuel hose. and there is no pressure. Just a little bit of fuel.
I decided that this is the fuel pump. I took off his tank, bought a new fuel pump. The pump has not changed. Today I decided to apply voltage to the old pump, it still stands in the tank. It works. Buzzing. Then I decided to check the voltage on the connector. I turned on the ignition. The instrument appears briefly on 12 volts. They are only momentary. Now I think there should always be 12 volts? Fuel tank removed. All hoses are disconnected. Not really the problem in the fuel pump? How to troubleshoot? Where can I get the wiring diagram?

I have an engine noise on my 2000 Dodge Caravan with the 3.3 engine. It sounds a lot like the grinding of a rotating part. It occurs at start up, momentarily, then goes away. If I drop it in gear and start doing low speed maneuvering in the driveway, it comes back. If I turn on the AC it comes back. In all cases, the noise goes away at around 1200 rpm.
The noise occurs again, when I shut the engine down.The engine performs and runs smooth and normal otherwise. No stalling, stumbling, or bad gas mileage to report.
I can "feel" the noise with my hand, when I put my hand on the ac compressor bracket, or the intake manifold, or the valve cover. I've tried the listening through the stick method, and it seems to be coming from the front area of the engine. But I can't be sure. It is something internal. Let me describe:
I thought it was my AC compressor or clutch going bad. The fact that my AC had stopped working well, and was making jet engine noises at high rpm supported me decide this. I replaced the compressor. The AC works great now, and the jet engine noises went away. But the grinding noise is still there. As described.
I wishfully thought it was the belt tensioner or idler pulley. I replaced both of those. Noise still was there. I pulled off the serpentine belt, and started the engine. It made the noise, very briefly as it started, then went away completely. It made the noise again briefly as I shut the motor off. So it's still there without any of the accessories turning.
The noise is loud and obnoxious at idle when under load. It just can't be good. I've read theories about similar sounding problems, saying they could be loose timing chain, bad oil pump, slapping pistons, crank journals, flexplate/flywheels cracked.
I'm going to try doing an oil system flush, and then I'll change it out with a little thicker oil. See if that makes any difference in the noise. Currently I'm running 5w-30 Mobile 1. I think. I'll let you know if it changes anything. I'm also thinking I want to make a short video of the car idling and making the noise for my video camera. I'll post that on youtube and link it here.

I had a VERY bad leak, to the point where I would fill it, an hour later it all leaked out. I had a mechanic work on it, and he rebuilt the PS pump, BUT the pulley was cracked, they DON'T make that size anymore. He put a bigger one on, only to find out, it was rubbing on my brake lines so I couldn't drive it! SO I had another grease monkey work on it, went through a few new pulley's FINALLY found one! BUT went through 4 Serpentine belts!!
After 3 months with NO VEHICLE, we finally got it all back together. BUT now it is not all lining up we couldn't tell until we had the belt on. it is about a 1/4 of an inch to much to the right.
I'm thinking maybe washers or spacers would work?
