Are You Having Car Problems? Here Are 5 Important Signs That Could Indicate a Failing PCM

Barack Diego
The powertrain control module (PCM) of a car is a specialized computer system that controls many aspects of the engine. It is also commonly referred to as the ECM or EMU. Having a faulty PCM is a serious problem that needs to be sorted out immediately. According to the National Motor Vehicle Crash Causation Survey (NMVCCS) conducted between 2005 and 2007, it was reported that vehicle-related critical issues were the second leading cause of automobile accidents. This clearly demonstrates the dangers of not addressing crucial engine problems at the right time. Listed here below are some of the main symptoms that could indicate a failing PCM. If you notice any of these signs, be sure to contact Car Computer Exchange who will send you a fully-repaired and functional Ford PCM within a short time. Here are the important signs to look out for:

1. Engine stalling

Do you find it difficult to start your car in the morning? Persistent engine stalling could be an early indication that your PCM is faulty. Also, if your engine has developed the habit of suddenly switching itself off while you are driving, then this is another sign that you should definitely get the computer system checked. If you continue to operate a vehicle with a faulty PCM, then the problem will only get worse and worse.

2. Appearance of error lights or warning signs

Have you recently noticed some strange warning lights appearing on your dashboard when you switch on the engine? These signals are usually red in color and they tend to flash on and off continuously depending on the make of car that you have. If you are unsure about the meaning of a particular warning sign, go to your car’s instruction manual and look for the section that explains the meaning of different symbols on the dashboard.

3. Reduced fuel efficiency

Have you noticed a sudden change in the fuel consumption of your car? A simple way to determine this is to look back at previous months and calculate an average of how much you usually spend on gas in a week. If this figure is much lower than what you are currently spending, then this could mean that your PCM is not functioning properly.

4. Excessive emissions

The PCM controls the type and quantity of emissions produced by your car. So, if you notice dark-colored or foul-smelling emissions, then this could be an early indication that something is wrong with your PCM. If you notice such emissions, then you should immediately stop operating your vehicle until the problem is fixed. This is because dangerous emissions cause environmental degradation and can lead to serious health problems.

5. Recent history of trauma or environmental damage

If your car has recently been involved in a car accident, then you should definitely check for PCM damage. This is because your car’s computer system is very sensitive and it can be damaged by excessive force among other factors. In addition, environmental factors such as flooding or snow can also cause serious damage to the PCM.
