Quick Summary
- The PCM is central to engine and transmission control.
- Replacement requires 0.9 hours for R&R.
- Relearn of powertrain and engine modules each take 0.5 hours.
- Engine Control Module reset is 0.3 hours.
- PATS reprogramming is mandatory after installation.
You’ve noticed your 2013 Ford Taurus 3.5L acting strangely—perhaps it stalls during acceleration or the check engine light remains on. The Powertrain Control Module (PCM) sits at the heart of these problems, coordinating fuel delivery, ignition timing, and transmission shifts. Understanding how to replace and reset this module can save you time and prevent further damage. This article walks you through the process step-by-step, from locating the PCM to ensuring it’s fully calibrated with the vehicle’s systems. By the end, you’ll know what to expect and how to keep your Taurus running smoothly.
What the PCM Does in a 2013 Ford Taurus
The PCM in the 2013 Ford Taurus 3.5L serves as the brain of the powertrain, interpreting sensor data and controlling engine and transmission operations. When it malfunctions, it may trigger codes such as P0606 and manifest as poor performance, erratic idling, or even failure to start. This module is part of the broader Powertrain Control Module replacement for the 2013 Ford Taurus 3.5L system, working closely with the Engine Control Module and the Passive Anti-Theft System. Proper replacement and calibration are essential for restoring full powertrain functionality and ensuring the vehicle’s safety systems remain active.
Where the PCM Is Located and What Replacement Involves
The PCM is located under the hood, close to the engine block, and accessed by removing the engine cover. The book time for removing and reinstalling the PCM is 0.9 hours. After removal, the engine control module relearn procedure takes 0.5 hours, while the powertrain relearn also requires 0.5 hours. Once the new module is seated, a reset of the engine control module, which takes 0.3 hours, finalizes the installation.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module R&R | All configurations | 0.9 hr |
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.9 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
Programming Requirements After Replacement
After installing a new PCM, the factory requires a relearn of both powertrain and engine control functions. Because Flagship One units arrive VIN‑programmed, those relearn steps are already completed, so you only need to perform the relearn checks. The process is straightforward and confirms the module’s alignment with your vehicle’s specific configuration. This VIN‑programmed replacement unit eliminates the need for manual reprogramming steps that would otherwise be required.
Symptoms of a Failing PCM
When the PCM fails in a 2013 Ford Taurus 3.5L, you may notice a hard start, stalling while cruising, or a sudden loss of power. The check engine light may illuminate and the engine may misfire, often accompanied by the P0606 code. In some cases, the diagnostic scanner will report a dead link to the PCM, indicating communication failure. These symptoms arise because the module can no longer accurately interpret sensor data or send correct commands to the engine and transmission systems.
Module Trouble Codes on the 2013 Ford Taurus
The 2013 Ford Taurus 3.5L can generate specific trouble codes that point to PCM issues. Understanding these codes helps you diagnose the root cause of performance problems.

Protecting the PCM in Your 2013 Ford Taurus
- Maintain a healthy charging system to prevent voltage spikes.
- Keep PCM connectors clean and free of corrosion.
- Avoid exposing the module to extreme temperatures.
- Respond promptly to any diagnostic codes that appear.
- Ensure all ground connections are tight and secure.
- Check connector seals regularly to prevent moisture ingress.
Frequently Asked Questions
How long does a PCM replacement take on a 2013 Ford Taurus 3.5L?
The typical labor time is 0.9 hours for the PCM removal and installation, plus 0.5 hours each for powertrain and engine relearn procedures, and an additional 0.3 hours for engine module reset.
Do I need to relearn the engine or powertrain after installing a new PCM?
Yes, relearn is required for both the powertrain and engine control modules to ensure they are synchronized with the new PCM. The relearn times are 0.5 hours each.
Will the Passive Anti-Theft System need reprogramming after a PCM replacement?
Reprogramming the PATS is mandatory after a PCM replacement. However, Flagship One units come VIN‑programmed, so this step is already completed.
What symptoms indicate a PCM failure in this vehicle?
Common signs include hard starts, stalling, loss of power, misfire codes, and a persistent P0606 code. A dead link to the PCM on a scan tool also suggests failure.
Can I skip the engine module reset after installing a new PCM?
The engine module reset, which takes 0.3 hours, is part of the post‑installation process to clear residual data. Skipping it may leave old data that could affect performance.
When your 2013 Ford Taurus 3.5L shows signs of PCM trouble, you can choose a repair that follows the factory’s recommended steps or opt for a refurbished replacement that comes pre‑programmed. Either option can restore your vehicle’s performance and reduce future downtime.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2013 Ford Taurus with a lifetime warranty, free shipping and no core charge. The full Ford Taurus module lineup covers other engine configurations as well.
Final Thoughts
For the 2013 Ford Taurus 3.5L, a PCM replacement can resolve many engine and transmission issues. By following the correct installation and relearn procedures, you’ll keep your vehicle running reliably. Reach out to a trusted technician if you encounter persistent problems.
