Ford F150 PCM Failure Symptoms & Solutions To Fix

Your Ford F150’s PCM (Powertrain Control Module) is akin to its brain. It makes your truck run more efficiently. But occasionally there may be issues with this crucial component. These issues have telltale symptoms, such as when you feel ill and have a temperature. In this article, we’ll discuss these symptoms and warning indicators that indicate a PCM issue with your F150.

The “Check Engine” light may come on if the PCM is having issues. When you’re really thirsty on a hot day, your truck may start to consume more gas. When you feel weak or dizzy, it might also cause your F150 to feel wobbly or stall. Your truck’s gears could occasionally not shift correctly, making it challenging to drive. In this article, we’ll delve into some common Ford F150 PCM failure symptoms and solutions to fix them in detail.

Understanding PCM Failure In A Car

Failure of the Powertrain Control Module, or PCM, indicates that your Ford F150’s critical brain is malfunctioning. This “brain” (the PCM) acts as a manager, ensuring that the truck’s engine, gearbox, and other vital components all function properly. When the PCM malfunctions, it might lead to some issues. These include things like your truck stalling or running rough, the “Check Engine” light turning on, it using more gas than it should, and the gearbox acting strangely.

This occurs as a result of the PCM’s diminished capacity to perform its duties. Therefore, recognising these problems and being aware that you might need to repair or replace this crucial component in order to keep your F150 in good operating order is the key to comprehending PCM failure.

Explain Ford F150 PCM Failure Symptoms

Your Ford F150’s PCM acts as the engine’s brain, directing how it operates. Your truck, however, can exhibit certain warning signals if something is wrong. The following are typical signs of a PCM issue:

1. Check Engine Light:

The PCM may be malfunctioning if you frequently see the Check Engine Light (CEL), especially if it stays on. The PCM evaluates the condition of your truck and alerts you through this light if there is a problem.

2. Bad Gas Mileage:

Your PCM may be having trouble getting your F150 to run properly if it suddenly becomes thirsty for fuel and you find yourself stopping at the gas station more frequently.

3. Strange Idling Or Stalling:

Your truck may be experiencing PCM issues if it stalls unexpectedly or feels unstable even when it is merely standing still.

4. Gearbox Issues:

Your gears may be acting strangely if you’re changing too quickly or late because the PCM isn’t communicating properly with the gearbox.

5. Power Issues:

Your F150 might not be receiving the proper signals from the PCM if it feels less powerful and has trouble gaining speed.

What Are The Causes Of Ford F150 PCM Failure?

Understanding the causes of PCM (Powertrain Control Module) failure in a Ford F150 is crucial for efficiently preventing or resolving problems.

1. Wear And Age:

Like any other component of your truck, the PCM in your F150 can become worn out over time. There may be issues if the electronic components within deteriorate. This ageing process can be slowed down with routine maintenance.

2. Voltage Jumps:

Voltage spikes can occasionally be caused by electrical issues, such as a malfunctioning alternator or problems with your truck’s wiring. Because the PCM is sensitive to variations in electrical voltage, these spikes could be harmful. This can be avoided by quickly repairing electrical problems or installing a surge protector.

3. Moisture Damage:

Electronics and water don’t mix nicely. Leaks or flooding can cause water to enter your F150, which can harm the PCM and other electronic components. To prevent water damage, be sure to fix any leaks and steer clear of driving in deep water.

4. Corrosion:

Moisture or exposure to extreme circumstances can cause corrosion to form on the connectors and wiring of the PCM. Failure may result from the electrical signals being disrupted. To avoid corrosion, regularly check and clean these connectors.

5. Production Errors:

A manufacturing flaw in the PCM itself can occasionally be the root of failure. Consult your dealership or a reputable mechanic if you have any suspicions.

Therefore, knowing these reasons can help you prevent problems and deal with PCM problems as soon as they arise, keeping your Ford F150 in good working order.

Solutions To Fix The Ford F150 PCM Failure?

When the PCM (Powertrain Control Module) in your Ford F150 malfunctions, it’s critical to fix the issue right away. Here is a thorough examination of the PCM failure sets:

1. Diagnostic Scan:

To start, have an auto repair shop or certified mechanic perform a diagnostic scan. This scan will pinpoint the precise problem with your PCM and direct the fixing procedure.

2. Repair Or Replace:

You have two choices, depending on the degree of PCM damage. It could be possible to fix a minor issue, such as a broken component on the PCM board. When compared to a complete replacement, this may save you money. However, a replacement may be required if the PCM is seriously harmed or outdated.

3. Expert Assistance:

PCM replacement and repair call for specialised tools and experience. It is strongly advised to get help from a qualified mechanic or technician who is familiar with your particular Ford F150 model and its PCM.

4. Aftermarket Or OEM:

You can choose between an Original Equipment Manufacturer (OEM) or an aftermarket PCM when replacing it. Ford manufactures OEM parts, which are often more dependable but also more expensive. Although they may be more affordable, aftermarket choices can range in quality.

5. Programming:

Make sure the PCM is correctly programmed to match the requirements of your car, whether it is new or repaired. Performing this step will guarantee that your F150 runs without a hitch following the repair.

6. Prevention Techniques:

Maintain the electrical system in your truck, take care of any wiring issues right away, and adhere to a regular maintenance programme to avoid PCM problems in the future. This will support the long-term maintenance of both your PCM and your F150.

In order to handle PCM failure in your Ford F150, diagnostic scans, expert assistance, and a decision between repair and replacement are required. By following these instructions, you can make sure that the PCM problems with your truck are effectively fixed, allowing you to get back on the road in a smoothly operating vehicle.

What Is A Repairing Cost To Fix The Ford F150 PCM Failure?

Depending on the degree of the damage, labour costs, and whether you choose a new or refurbished PCM, the cost to repair a Ford F150 PCM can range from $300 to $1,200. Simple problems may merely require reprogramming, which costs about $100. However, the cost increases if a complete replacement is necessary.

Mechanic rates and location affect labour costs as well. For a precise diagnostic and cost estimate, always consult a qualified mechanic. Keep in mind that fixing PCM faults right away can avoid more serious and expensive engine problems in the future.
