Are the powertrain control modules in a 2004 Dodge Ram and 2008 Dodge Ram the same?
We are trying to figure out the trucks problem. I got a p0601 code as well as ignition coil codes and evap system codes. We bought a truck from a dealer and the engine went out within a week, they replaced the engine with an 04, they disabled our check engine light in the process and i doubt they changed out the pcm to match the current engine that was put in. Would a pcm for a 2008 cause a 2004 engine to have ignition coil codes, and evap system codes. Im trying to figure out if I just need to get the right pcm or is this worse than im thinking?

Experienced mechanics share their insights in answering this question :
The powertrain control module (PCM) part numbers for the 2004 and 2008 model year trucks are different. So, it’s possible that the PCM could be the problem. However, there are countless things that could have gone wrong with an engine swap like this. Just one wire being left disconnected could cause all kinds of problems, including those you describe. I recommend taking the vehicle back to the shop that did the repairs to demand they make things right. If that doesn’t work, the team at YourMechanic would be happy to diagnose and repair your Dodge.
How to Identify and Fix Common car Problems ?

The PCM–or powertrain control module–in a Dodge is responsible for controlling many of the electrical systems in the vehicle. This includes airflow to the engine, temperature and more.
The PCM, or powertrain control module, is your vehicle`s onboard computer. PCM Reprogramming or reflashing is essentially a software upgrade and may be required to resolve a hot or cold starting issue, idle roughness, stalling, or an emissions failure.
It`s important to note that when you disconnect the battery on your Ram 1500, it not only resets the engine light, but the computer, and also resets the vehicle`s security system and other electronic systems.
Common signs of a failing PCM/ECM/ECU include the Check Engine Light coming on, engine performance issues, and the car not starting.
The powertrain control module (PCM) is an integral part of a vehicle`s performance. It controls all functions related to the powertrain, from gear changes to transmission control and engine management. By coordinating every task digitally, PCMs can increase fuel economy and offer improved power delivery.
Any time your car`s informative display shows a powertrain warning light, it should be a matter of immediate concern. If you go on without being vigilant then you are in for a rude shock. Signs of a powertrain malfunction are; Reduces speed, Unusual handling, Overheating, and Growling noise under the bonnet.
PCM (Powertrain Control Module) – This is a combined engine and transmission control unit which will provide management and correct function of the engine and transmission from one control unit. ECU (Engine Control Unit) / ECM (Engine Control Module) – This is an electronic control unit that manages the engine only.
Check the voltage of the battery in the PCM using a multimeter. Set the multimeter to DC volts and connect its probes to the battery terminals. The reading should be around 12V. If it is lower than 10V, then check for any loose connections or other issues with the power supply before proceeding further.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
PCMs are built with microchips that can be reprogrammed electronically without being removed from the vehicle. Reflashing is a process where you electronically transfer approved files from a vehicle manufacturer`s website using a diagnostic connector.
Not to mention, if you go the route of replacing your faulty PCM, you`re able to save cost on labor by simply replacing it yourself. All you have to do is make sure you identify the correct PCM for your particular vehicle—because there are a lot of different types and you want to avoid unnecessary returns.
When a battery drains, it may send lower voltages of power which may or may not hurt your PCM. But it can definitely cause some problems that are related to your PCM due to it not receiving enough voltage. Also, your PCM can create problems that aren`t caused by your battery too.
The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.
You plug an OBD-II scanner tool into it and, in most cases, out pops a code that tells you what the problem is. The scanner also allows you to clear the vehicle`s internal code, which is what triggered the check-engine light. Do that, and the warning light will turn off.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.

If it is lower than 10V, then check for any loose connections or other issues with the power supply before proceeding further.
PCM`s typically fail for one of two reasons: voltage overloads (often due to a short in a solenoid or actuator circuit) or environmental factors (corrosion, thermal stress or vibration). If water gets inside a PCM, it can short circuits and set up irreversible corrosion that ruins electronic connections.

hi, I need some help to decide weather to purchase a 2000 dodge ram 1500 magnum or a 2003 dodge ram 1500 small engine
ANSWER : On the 2000 magnum you can expect to pay $500 on tires. If the 2003 had an overheating issue, whether or not it get fixed is a concern. The 2003 is a newer vehicle even though it has 15k more miles. My best guess could possibly not be very accurate, since it comes down to the condition and how good they look to me.
I would recommend having a professional mechanic do a complete pre-purchase inspection on both trucks in order to give you an idea of the problems they may have. Afterwards you’ll have the information to make an informed decision.
transmission control module failing. We just replaced the computer module (pcm) 4 days ago?
ANSWER : The P0700 trouble code is a code for transmission control module (TCM) failure. Without knowing the other codes, it will not be possible to give you an accurate answer; it all depends on the other codes:
If you get a P0755 code, you may have a transmission solenoid pack issue.
P0725 indicates a likely crank position sensor issue.
I would suggest having your Check Engine Light diagnosed by a qualified mechanic.
ABS, ESP, EBR malfunction
ANSWER : You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.
Trying to change 2002 Dodge ram 1500 5.9 ltr engine with 2000 Dodge ram 1500 5.9 and motor mounts don’t line up
ANSWER : Hi there. Although the engines are the same size internally, it is very common for manufacturers to change the location of engine mounts both on the engine and the interior of the engine compartment. Unfortunately, this type of swap would require some fabrication of the motor mount location in order for it to fit correctly.
How often should you replace drive belt on 2008 dodge ram
ANSWER : The recommended replacement interval for all of the belts on the 2008 Dodge Ram 1500 is 120,000 miles so yes the belt should be replaced if it is the original belt. There are many other components and systems on the vehicle that should be thoroughly inspected, though, if you have not done so already. YourMechanic offers a comprehensive pre-purchase inspection and such an inspection would assist you in making the wisest possible decision and, if need be, seeing to it that other deficits in the vehicle are addressed or that the price is adjusted accordingly. Please let us know if you have further concerns or would like to set up an inspection.
Engine control modules replaced on a newer car
ANSWER : Hi there. These modules are common failures on the Jaguar XF. I am sure that this does not make you feel any better about it, but from my experience, once the modules are replaced you usually do not have any further issues, assuming that new factory modules were used. Many times these modules fail due to voltage issues in the electrical system, so it is important to always make sure that the battery and alternator are good and that all do the ground connections are clean and tight. Your car should be fine for now, but if it begins to have drivability issues, you may want to start looking to sell the car.
I have a 2008 Dodge Ram 1500 Quad cab it will start when the engine is cold but when the engine is warm it won’t start I have to w
ANSWER : Hi there. When you can’t start a vehicle when it’s hot, the most common sources are the fuel pump, spark plugs, cap + rotor, coil, fuel filter, starter, battery cable, or a wiring harness fault. Since so many different systems can cause your car not to start it should be diagnosed by having a professional mechanic complete a car is hard to start inspection.
