Replacement Cost Of Pcm
PCM is a computer, and computers are usually expensive. The replacement cost of the powertrain control module varies according to the vehicle model and labor cost. The average cost to replace a PCM is from $945 to $1,040.
The labor cost for PCM replacement is between $60 and $120. You can save labor costs by replacing it yourself, but you need to use software to configure and program the powertrain for this task. So, we always recommend visiting the proper technician for powertrain control module replacement.
There may be a chance to find a used powertrain control module at a low price from a junkyard. But you still have to spend some money on its installation and reprogramming.
What Is Meant By Reflashing A Pcm
Basically, reflashing a PCM means upgrading the software. PCM is equipped with an electronic chip. These chips can be reprogrammed electronically, without having to remove the PCM from the car.
Reflashing is the process where you send approved files from the manufacturer to the PCM, thus upgrading its software. The process is done using a diagnostic connector.
Powertrain Control Module Identification
Because there are so many different PCMs, accurate identification of the PCM and its correct replacement is absolutely essential to prevent unnecessary returns. Many PCMs appear to be exactly the same on the outside but may be wired or calibrated differently inside.
If the wrong PCM is installed in a vehicle, it may run but probably will not run well. Close enough is not good enough when it comes to replacing PCMs. It must be the correct replacement for the application.
Accurately identifying the PCM requires not only the vehicle year, make, model and engine size, but also the OEM part number on the PCM itself. Most supplier catalogs list replacement PCMs both ways. So if in doubt, always refer to the OEM number on the PCM and look it up in the suppliers cross reference index to find their replacement part number.
The calibration chip and PROM contains the programming instructions for the vehicle application. That is why it usually does not come with the replacement PCM. There are too many different possibilities. On many newer vehicles, flash memory or “EEPROMs” are used. If the replacement PROM is not properly programmed for the application, it must be reprogrammed after it has been installed.

There Are Two Types Of Pcms: On
There are two types of PCMs: on-board diagnostics and OBD II.
The difference between OBD and OBD II is that the former was mandated for all vehicles in 1996, but the latter up to 1995. The most noticeable difference is that OBD II is a 16-pin diagnostic link connector whereas OBD utilized a 12-pin connector.
OBD II helped auto manufacturers better track emissions systems and potentially spot defects more quickly. This system also has standardized diagnostics across the board any mechanic with an OBII scanner can diagnose just about any vehicles issues, regardless if its a Ford or a Toyota.
How To Check For Physical Damage
The PCM is a silver box that sits in your engine bay. Some cars may have their PCM behind the dashboard or in the trunk, so check with your owners manual to find where it is. Once you find it, see if theres any physical damage to the box. If theres damage, well thats confirmation of why your PCM is bad.
But if there isnt, you will need to inspect it further. But before we proceed, keep in mind that this process can be risky if you dont know what youre doing. If you dont see signs of physical damage right away, we recommend reprogramming the PCM first and see if the problem persists. Reprogramming a PCM is much cheaper than replacing it. With that being said, heres how to inspect it further:

Bad Powertrain Control Module Symptoms
The most common symptom of a bad PCM is poor engine performance together with a check engine light on your dashboard. You may also notice problems with the transmission like shifting issues. Poor fuel economy and increased emissions are quite common also.
While its not common for a PCM to break, it does happen from time to time. Before you jump straight to the PCM, though, rule out any other potential causes.
Here is a more detailed list of the six most common symptoms of a faulty PCM below with that noted caveat.
You Should Know What The Pcm Does In Case It Has A Problem
Since the PCM is so important, you should know how to recognize when its having problems. The symptoms are varied, but they mostly revolve around poor engine performance. For example, your car may not start at all or it might take a long time for the engine to turn over. If the PCM has become faulty, you might also notice that your vehicle stalls frequently or loses power while driving. These are just some of the possible issues that can arise if you have a bad PCM. If you suspect your PCM is malfunctioning, you should have it replaced or repaired as soon as possible in order to avoid further damage to your car and ensure optimal performance from your vehicle overall.
When you take your car in for repairs, the mechanic may mention that your Powertrain Control Module is malfunctioning. Many drivers mistakenly think that this part controls the transmission, but its actually responsible for overseeing many other functions of your vehicle. There are many reasons why this module might be failing, and its important to have your PCM checked if you notice any unusual issues with your cars performance.

PHEV stands for Plug-in Hybrid Electric Vehicles. These are cars that use both a gasoline engine and an electric one, like the Toyota Corolla Cross or RAV 4.
What is better, a hybrid or plug-in hybrid?
Hybrid is better. For now. A plug-in hybrid relies more on the batteries than a normal hybrid and therefore needs more charging. A full hybrid is able to recharge its batteries with its own wheels, brakes, and other components.
Should I charge my plug-in hybrid every night?
You do not need to charge your plug-in hybrid every night. This can shorten the battery life of the car just like a phone. Its best to charge it when its lower than 50%, and then to take it off charge as soon as it is finished. You do not want to leave it plugged in all night.
What are the disadvantages of a plug-in hybrid car?
The batteries are awesome for fuel consumption and power, but they are really heavy. Weight has a serious effect on the performance of a car in terms of handling, gas mileage, and speed.

How Do They Work
What is a PCM on a car? To know that, you should know how it works.
The Engine Control Module takes information from multiple sensors from your car and adjusts the engine settings accordingly so it can drive smoothly. The ECM takes information from the exhaust system, cooling system, air intake, and other components.
Afterward, it will make changes to the engine settings accordingly.
For example, if your engine isnt getting enough air, the Engine Control Module will reduce the fuel so it gets complete combustion. The ECM can also control other things like the camshaft, throttle position, and ignition timing.
Much like the ECM the Transmission Control Module or TCM controls several components in a car. By using data from the sensors in your car it controls the transmission similar to the way that the Engine Control Module controls the engine.
Only vehicles with an automatic transmission use the TCM, while manual transmission cars only use the ECM.
For example, the rev-matching function in many sports cars is done by the ECM. It matches the clutch and engine speeds during shifts automatically by using data from the ECM. Older TCMs will decide on switching gears by accounting for the speed of the car and the engine.
Modern ones, however, take more input, this includes data from the cruise control, throttle control as well as traction system. Modern TCM not only decides when to shift but also helps reduce wheel spins and gear hunting.

In Addition To Monitoring The Health Of The Vehicle The Pcm Also Controls Certain Operations Such As When To Shift Gears
In addition to monitoring the health of the vehicle, the PCM also controls certain operations, such as when to shift gears. The data collected by sensors is used to determine when its time for a shift, and it sends a signal that tells the transmission or transaxle to change gears. This information can be adjusted by the PCM in order to optimize performance and fuel economy. Depending on what kind of driving youre doing, different shift points may be favored over others. For example, if youre pulling a heavy load up a steep hill on an icy road, the PCM might adjust its shift points so that you dont slide backward as you accelerate.
This is just one example of how your vehicles computer system works behind-the-scenes to keep things running safe and smoothly. As technology evolves, we will likely see more advanced versions of these systems in our cars and trucksand they will become more reliable with each iteration too!
Sudden Loss Of Gas Mileage
One function of your PCM is to work with the ECM and TCM to control your fuel-to-air ratio and decide when to shift gears. If either of these functions isnt working optimally, your gas mileage will suffer.
Of course, there are other reasons for poor gas mileage as well. Check your tires to make sure theyre properly inflated, and make sure your filters have all been replaced as scheduled. If these things are up to date, its possible theres something wrong with your cars computer system.

Check Engine Light And Error Codes
The PCM will register an error code when it finds a problem with the drivetrain or transmission that it possibly cant fix by itself. When it registers an error code, it will flash the check engine light letting the driver know that there is a problem.
Although, a faulty PCM might display the wrong error codes or register an error code while there are no errors.
When connecting to a cars computer with an OBD 2 scanner, you can determine the problem code. From there, an OBD 2 scanner will scan your computer and display an error code. For example, code P0301 means there is a misfire problem in the cylinder.
However, if youre not experiencing any misfire issue, then your PCM has registered a false error code, in which case the PCM might be faulty. Keep in mind that this problem may also stem from a faulty sensor.
However, once youve verified that theres no actual issue with the vehicle, then you can narrow down the problem into either the PCM or a faulty sensor.
How Can I Save Money
There are two ways to reduce the cost, first, you can get non-OEM Powertrain Control Modules. These are control modules that are not made by the cars original manufacturer but can be used for your car. Youll need to identify your cars PCM part number, and you should be able to find plenty of them online.
The second option is to use remanufactured PCMs. These are used OEM PCMs thats been restored to factory specifications and are now as good as new. You should also be able to find plenty of these on the internet, and both options typically cost somewhere around $250 $400.
However, before buying either of them, you need to check the reviews. Make sure customers are happy with their purchases and that these PCMs work well, and ensure that they will fit your car. And finally, buy a PCM that has a warranty, so if it fails, you wont have to buy a new one.

What Does The Tcu/tcm Do
The transmission control unit/module oversees the function of automatic and dual-clutch transmissions. This module reads vehicle speed sensors, transmission fluid temperature, throttle position, and more.
The TCU/TCM decides when to change gears to optimize performance, acceleration, and fuel economy. When you drive a car with an automatic transmission, the effortless shifts that always happen at the right time are a direct result of the TCM/TCU.
Vehicles with manual transmissions do not have a transmission control unit/module because the driver is the one making the decisions!
Whats A Transmission Control Module
The Transmission Control Module does exactly what it sounds likecontrols your cars transmission. Similar to the ECM, in automatic transmission vehicles, the TCM takes in information and data from various switches and sensors in your car. These switches and sensors include those monitoring the positions of the gas and brake pedals, the transmission input and output speeds, gear selection, engine torque and speed, oil temperature, and wheel speed.
The TCM collects the information from all the sensors and determines when your transmission should shift gears. Traditional manual transmissions dont need a TCM because the driver is shifting the gears themselves, but in automatics this component determines how and when your car should shift in order to produce the most efficiency and torque, given the signals it receives from all the sensors around your engine.

What Is A Pcm
As you likely already know, almost all modern cars and trucks feature some degree of onboard computerization. One of these onboard computers is known as the powertrain control module or PCM for short. Typically, these modules act as the computerized brain that controls the two primary components of the powertrain, those being the engine and the transmission.
That being said, the PCM may be tasked with automating and performing over 100 functions for a single vehicle at once. To accomplish this, a PCM unit is connected to numerous sensors throughout a vehicle that tracks everything from wheel rotation speed to engine temperature. When one of these sensors fail or the PCM outputs an error, a driver is typically informed of the fault when their check engine light flips on.
Though it goes without saying, a vehicle that utilizes a PCM simply cannot function properly without one. Thats because your car would not be able to regulate its own functions without the PCMs brain involved. As such, any known short circuit in your vehicles PCM is a cause for concern. A replacement will almost certainly be necessary unless the problem can be chalked up to an issue with the PCMs software .
