Signs Your 2006 Ford Explorer PCM Might Be The Problems

All of our autos’ systems were manual not long ago. And one had to keep an eye on every component of his/her vehicle, from timing to tire pressure, and mechanics would routinely give your automobile a “tune-up” along with an oil change. Have you ever wondered why something isn’t required any longer? The reason for this is because of the computer system in your vehicle. The control module for the powertrain is a single computer in charge of these systems (PCM).

The transmission control module (TCM) and the engine control module (ECM) are two components of the engine control module. While today’s automated automobiles are more dependable and efficient than ever before, earlier. In the event that a computer malfunctions, it can have a wide range of consequences for the vehicle. We’ll let’s see into common Symptoms of PCM failure and what they indicate for your automobile

1. The Check engine light on your vehicle is on

The check engine light illuminates as a warning, and several test fault codes should appear. When this light appears on your dashboard, it usually indicates that the 2006 Ford Explore Engine Control Unit (ECU) is malfunctioning. The mechanic will first clear the error code and check if the indication is correct and the sensors are in good working order. The next step is to figure out where the problem is based on the methods listed in the code.

Your PCM may be destroyed if everything in your car is in working order, yet the check engine light is illuminated. Depending on the extent of the damage, you can replace the damaged portion of the complete machine. However, a lousy PCM shouldn’t be a cause for concern, and many jurisdictions allow drivers to pass inspections even if the engine light is illuminated. However, the sooner you address it, the better your engine will run, and you’ll be able to protect other parts and systems that could be harmed.

2. Your vehicle fails to start or artlessly

Another PCM failing system could cause your car not to start or take multiple attempts to start. Various PCM issues can cause this, but it could also indicate a problem with your ECM.

The following are some of the possible causes:

• A fuel-to-air ratio that isn’t correctly adjusted
• Engine timing is incorrect.
• The wire harness has a short.

This is a severe issue since your car could fail to start while you’re trapped on a country road, in an empty parking lot or in unfavorable settings.

3. An immediate loss of gas mileage

The PCM collaborates with the Ford ECM and TCM to control the fuel-to-air ratio and determine when to shift gears. Your gas mileage will suffer if either of these functions isn’t performing correctly. There are, of course, other reasons for lousy gas mileage. Ensure your tires are properly inflated and that all filters have been replaced according to the manufacturer’s recommendations. If all of these items are current, it’s conceivable that your car’s computer system is malfunctioning.

4. Emissions test failed

The PCM and ECM in your car manage the fuel-to-air ratio. The fuel won’t fully combust if the mixture is vibrant (too much fuel compared to the amount of air), resulting in much more particulates and carbon monoxide than a well-running engine. You may fail your state’s emissions test as a result of this. Check your PCM and ECM first if your automobile fails. A failing PCM or PCM could be excellent news: replacing any of these systems is much less expensive than purchasing a new catalytic converter.

6. Random or erratic shifting

Rough shifting is one of the most extreme PCM failure symptoms. This is usually due to a defective sensor or water damage to some of the circuits in your vehicle’s your vehicle isn’t shifting correctly, take it to a repair right away. A faulty PCM or TCM might cause the vehicle to become stuck in gear, posing a significant safety risk. It may also result in expensive transmission damage.

7. A PCM-Related error code has been received

The error code is the last symptom on our list. When your PCM has an issue, it logs an error code that will appear on any code reader device linked to it. Congratulations if this is your first sign of problems! You discovered the issue before it became more serious. The U0100 code, the P0603 code, the P0113 code, and the P0606 code are among the codes we’ve already discussed. However, this is not an exhaustive list. A PCM failure is the most common code beginning with “P06,” although there are a few more. For further information on any codes, you see, consult your code reader’s manual.

8. Stuck Heater

Your car is heating up — it’s on fire, and it’s not in a reasonable manner. According to reports, the Ford Explorer tends to overheat when the heater is set to the highest. When the heater’s blend door breaks, the heater stops working correctly. You can imagine what would happen if this actuator failed, as it controls the temperature inside the car. The inability to set the temperature and a clicking sound reverberating from the actuator motor are symptoms of this problem. In this instance, get the heater blend door checked to catch any errors early. Replace it if it’s entirely broken. A heater replacement can range from $570 to $930.

9. Stalling and rough idle

Rough idling and stalling are two Ford Explorer issues that can cause serious harm to the vehicle. The intake manifold’s O-ring gaskets may leak, resulting in a vacuum leak. The O-ring gaskets seal off several sections, providing the perfect lock. Air can quickly enter the fuel and engine system if there is a vacuum leak. The engine cannot deal with the increased air pressure and begins to fail—gaskets for the intake manifold cost between $700 and $950.

10. Fuel inefficiency results in a reduction in mileage

A sudden decrease in gas mileage should prompt a PCM diagnostic. The PCM controls the fuel-to-air ratio and tells the engine when to change gears. You will lose gas mileage whenever this function fails, albeit there are various additional causes for this condition. Faulty ECMs can lead to inefficient combustion patterns and lower overall fuel economy. If the engine is unsure how much fuel to burn or the automobile has transmission problems, it will consume more fuel to cover a shorter distance. It is critical to keep track of your vehicle’s fuel consumption.

Conclusion

There are several other signs and symptoms of a defective engine management system. For some, it’s only a simple error signal that appears when your engine computer is malfunctioning. Because other faults with your automobile can cause bad PCM symptoms, you should have a trained repairer inspect it and restore the computers to regular operating order. PCM problems can lead to more significant problems. Therefore it’s best to fix them as soon as possible. It’s essential to be aware of the negative PCM symptoms.
