Replying to: xwesx (Jun 04, 2009 8:54 am) Don't leave out the O2 sensor in that mix. I believe most engines run "open loop" (in that the output of the O2 sensors are ignored) for a couple of minutes upon start up, until the O2 sensor has a chance to warm up. The ECM uses one of the existing temperature sensors to figure out when this is.

Replying to: robopolo (May 16, 2009 1:49 pm) Okay y'all --- Here is the fix. I took it to a mechanic and he said start by replacing the ECM (Engine Control Module) to take care of the P0601 code. Chrysler dealer wanted $750 for a new ECM & $200 to program it (insert VIN # and Milage etc). I searched ebay and found this place in Florida (SOLO AUTOMOTIVE COMPUTERS, 1-800-886-9926 soloautocomcast.net) and paid $225 for a refurbished with all of the programming done and free shipping and lifetime warranty (as long as I own the vehicle). I installed it and it took care of the P0601 code but the transmission still would not shift. I read online and a Chrysler Mechanic said everytime he has seen the P0605 it has been a bad TCM (Transmission Control Module). I bought a refurbished one from SOLO for $230 free shipping & programming & lifetime warranty. I put it in an whala transmission started working and all error codes were gone. I hope this will be usefull to someone. I spent $455 and fixed it myself --- a dealer would have wanted $1500 to $2000 to fix it. So I saved $1000 to $1500 ---- That makes working on your own vehicles worth while!!!

Replying to: anotherday2006 (Jun 02, 2008 8:38 am) Did you resolve your problem? I have the same exact symptoms... it's like there's a rev limiter at 3500rpm whether its reve'd up with no load in park or driven with load in any gear (auto trans). The same code you got also came up (P0016) but I want to know the actual problem since you've already replaced those and got no joy. Any info greatly appreciated!

Replying to: mako511 (Jun 26, 2009 9:49 am) the P016 error with missing above 3500 rpm is the crankshaft flex plate (flywheel) that is cracked and the crankshaft position sensor is back there getting information from the flex plate. My leasing company had the dealer replace the cam and crank position sensors first with no fix. Pulling the transmission and replacing the flex plate (flywheel) fixed the problem.
#1786 of 1830 25-30 mph jerking computer learn fixed problem by cr119 Jun 30, 2009 (9:22 am)
Ok so I was getting the hard jerk when my 03 Dodge Grand Caravan was decelerating at about 25-30 mph. I first had the codes checked for free at auto zone there were none. Then I disconnected the battery overnight that did not work. I then took it to my local Dodge dealership (that was a mistake) the service advisor told me that it would take the tech at least 2 hrs to look it over at $80 an hour. I told him I would only authorize 1 hr. When they were done three days later he told me I needed a new front oil pump. Now I had already told him about the service bulliten someone recommened online stating that all that was needed was a computer relearn, he then told me they were wrong and it was going to cost me $900 to replace. I then called a local transmission shop the first thing they said was it needed a computer relearn and it would cost $60. And to my surprise it did fix the jerking problem!
#1787 of 1830 1996 Chrysler town and country by belongamick Jul 03, 2009 (8:37 am)
While driving the van in D position the transmission is very erratic it almost feels like the engine missing very bad, after a few seconds the transmission will shift into 2nd gear and stay there. If i select the 3 position next to the D it runs fine shifts through all three gears up and down just fine.Does anyone have an idea what could be causing this? i took it to autozone and had it scanned, no codes came up.Have no way to check transmisson codes. Thanks for any info.
#1788 of 1830 whine in 96 Voyager by hixb Jul 05, 2009 (5:44 pm)
96 Voyager has the small 4 cyl w/the 3 speed auto. 114,000 miles. Has always had some hum under the hood. But after 14 months of driving the whining has gotten so loud we parked it. I changed engine oil to a higher weight; no help but found no metal. Pretty sure it isn't the alternator ior the air compressor. It whine low while at idle but increases as you drive or rev up the engine. Afraid with all I have read the problem is the transmission. Will changing the trans oil/filter help? Any suggestions or advise? Thanks all. hixb Replies to this message: chessor (Jul 06, 2009 6:20 am)
