Take the car to a place that will read the ODBII DTC (diagnostic trouble codes in a PXXXX format) for free. Nearly every item on the car is monitored or controlled electronically and it's not a very big difference between power production and consumption when all is healthy. These cars are VERY finicky when available power fluctuates. If it is over 3 years old, consider a replacement. Very thorough inspection of wiring and connections along the backside of the engine and transmission especially if anyone else has attempted repairs or diagnosis.Ĭheck the age of the battery. Both unfortunately are often referred to as CPS since one is the Crankshaft Position Sensor while the other is the Camshaft Position Sensor. Without it connected since it seems to be part of the main issue.Ģ.5L engines have two primary sensors that control fuel timing and spark timing. This gives me an idea though to find out how useful the CPS actually is, and if I could run the car for a while I have to calculate this to the point I know exactly what to fix, before it's ran dead. She was just able to get to work before the car would overheat.Īs far as I can tell, the heads and block have not warped. I'm just lucky, no credit card companies will give her anymore cards to burn up, but I made a huge mistake mentioning AMScott to her.īefore I got to FL, she was driving the car without a working cooling fan for approx. So every few days sometimes a week before her payday, she let's her bank account get down into single digits, and comes begging me for money. Worst part of this is that even though she works she spends way beyond her meansĪnd can't manage her money at all, and I can't do a thing about it. Which gets very costly very quick, and ultimately continues to mess up my finances. I'm left with less than bare minimum in every situation unless I pay for it, I can work on her car anytime, and I don't have any problem when I know what needs to be done,īut I don't have access to it while she is at work unless she takes my car which isn't registered yet (dangerous) here in florida.Īs far as money goes I don't have any money to throw at all her stuff that seems to go wrong all the time,Īnd I would never ask her to pay me for fixing her stuff anyway. This being my mom's car, hence the name, I can't go and buy her the parts since I have my own car to deal with. Then needing to do all this in one session, and I can't afford to pay for it or throw money at possibilities. Possibly new computer, probably 30 at the junkyard, if they are not locked to VIN. However, from what I can tell all this requires some ground work,ĬPS $? probably 30 bucks at the junkyard.
#ECM RESET HOW TO#
Then fudging up the CPS, which this awesome video shows how to removeīut haven't been able to afford it, even from a local junkyard. Now, after some research I came to the conclusion the intermittent studdering in the idle, may have been from oil getting past the sparkplug seals. Lower fuel starved sounding rougher idle. Symptoms listed in order of occurrence in the last 6+ months:Īn intermittent kind of studder in the idle once the car is warmed up. So, what has you thinking about replacing something that we've rarely seen go bad? Have you been able to retrieve any DTC codes from a reader?īTW, I own a 99 with 240,000 miles on it.Īlright, reasoning behind me looking into the computer is simple. The "Key Dance" that is often talked about in most Chrysler forums does NOT work on these years. There is NO provision on this year, 98 or 2000 for readout of ANY DTC to the owner. Now for the worst part of the news, be very careful on the 99 model.
#ECM RESET CODE#
If you don't fix the cause of the code then it will come right back. Having thrown out that info, resetting any DTC's (Diagnostic trouble codes) is all that the removal of power does. The worst potential is the Sentry Key module which will completely disable the car.
#ECM RESET INSTALL#
It's not something to change out on a whim since you might get ahold of a module that has an activated option that your car doesn't have, install it causing the other related modules to pick up on that option and then report it faulted because it isn't there. Particularly any options that are security related. These communicate over an internal network called CCD (Chrysler Communications Databus IIRC).ĭepending on the specific model and options they can "imprint" one another. The PCM (Powertrain Control Module - Electronic engine management), the TCM (Transmission Control Module - Electronic transmission management) and the BCM (Body Control Module - Electronic interface for operator inputs and displays). There are three primary modules used on this year that talk to each other.
