2016 Dodge Dart PCM Replacement: Symptoms, Programming, and TSBs
The powertrain control module (PCM) in the 2016 Dodge Dart 1.4L manages engine and transmission operation. When it fails, you may experience no-start, stalling, or diagnostic trouble codes such as P0606, indicating an internal processor fault.
Quick Summary
- PCM replacement on the 2016 Dodge Dart 1.4L has a book time of 0.9 hours for the PCM itself, with an additional 0.5 hours for an ECM relearn if needed.
- The PCM ground strap is located at the lower most forward stud; ensure the ignition is off and battery disconnected before unplugging connectors to prevent voltage-spike damage.
- A new PCM must be programmed with the vehicle’s original VIN and mileage using a diagnostic scan tool per factory procedure.
- Two service bulletins address drivability and powertrain diagnostics: #18-059-18 and #18-009-15, both requiring a flash update.
- The internal trouble code P0606 is documented for this vehicle’s PCM, indicating a processor fault.
If your 2016 Dodge Dart 1.4L is experiencing drivability issues, a failing powertrain control module (PCM) could be the cause. The PCM is the central computer that controls engine timing, fuel delivery, and transmission shifts. This article explains what the PCM does in your Dart, where it is located, what replacement involves, and the factory programming requirements. You will also learn about common failure symptoms, relevant service bulletins, and how to protect the module from future problems. Understanding these details helps you make an informed decision about repair or replacement.
What the PCM Does in a 2016 Dodge Dart
The powertrain control module (PCM) in the 2016 Dodge Dart 1.4L is the primary computer that coordinates engine and transmission functions. It receives input from sensors throughout the vehicle and adjusts fuel injection, ignition timing, turbocharger boost, and shift points to optimize performance and emissions. Because the PCM directly controls so many critical systems, a failure can cause a wide range of drivability problems. If you need a replacement, you can find replacement PCMs for the 2016 Dodge Dart that are built to factory specifications. The module is essential for your vehicle to start, run smoothly, and pass emissions tests.
Where the PCM Is Located and What Replacement Involves
The PCM on the 2016 Dodge Dart 1.4L is mounted in the engine bay, with its ground strap (3) attached to the lower most forward stud. Replacing the module requires disconnecting the battery and ensuring the ignition is in the off position before unplugging any electrical connectors; failing to do so may cause a voltage spike that damages the PCM. The factory book time for PCM removal and replacement is 0.9 hours. If you are also replacing the engine control module (ECM), that job is listed at 0.5 hours, and an ECM relearn procedure adds another 0.5 hours. Access is straightforward once the battery is disconnected and the ground strap is removed from the forward stud.
How to Reach the PCM on the 2016 Dodge Dart
- Disconnect the negative battery cable.
- Disconnect the Powertrain Control Module (PCM) electrical connectors.
- Remove the three nuts.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module R&R | All configurations | 0.9 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.5 hr |
Programming Requirements After Replacement
After installing a new PCM in the 2016 Dodge Dart 1.4L, the factory procedure requires using a diagnostic scan tool to program the module with the vehicle’s original VIN and mileage. This step is necessary for the PCM to communicate correctly with other systems and to meet emissions regulations. When you purchase a VIN-programmed replacement PCM from Flagship One, that programming is already completed before shipping. Your unit arrives ready to install, saving you the time and expense of a dealer-level scan tool session. Simply install the module, reconnect the battery, and perform any required relearn procedures as directed.
Symptoms of a Failing PCM
A failing PCM in the 2016 Dodge Dart 1.4L often produces symptoms such as an engine that cranks but does not start, intermittent stalling, rough idle, misfire codes, or a check engine light. You may also notice poor acceleration, erratic shifting, or a complete loss of communication with a scan tool. One specific internal fault documented for this vehicle is the P0606 internal processor fault, which indicates the PCM’s processor has malfunctioned. If you experience any of these issues, especially in combination, the PCM should be tested or replaced.
Module Trouble Codes on the 2016 Dodge Dart
The following internal trouble code is documented for the PCM in the 2016 Dodge Dart 1.4L. This code indicates a fault within the module itself, not a sensor or wiring issue.

Factory Service Bulletins Worth Knowing
Two factory service bulletins apply to the 2016 Dodge Dart 1.4L PCM. Bulletin #18-059-18 covers a flash update for powertrain diagnostic and system enhancements. Bulletin #18-009-15 addresses drivability improvements specifically for the 1.4L engine. Both bulletins require a dealer to reflash the PCM with updated software. If your vehicle has not received these updates, you may experience unresolved drivability concerns that a flash can correct. Check with a dealer to see if these bulletins apply to your VIN.
| Bulletin | Subject | What It Addresses |
|---|---|---|
| 18-059-18 | Service Bulletins/Recalls • 18 – Vehicle Performance • Flash: Powertrain Diagnostic and System | — |
| 18-009-15 | Service Bulletins/Recalls • 18 – Vehicle Performance • Flash: 1.4l Drivability Improvements | — |
Protecting the PCM in Your 2016 Dodge Dart
- Keep the battery and charging system in good condition; voltage fluctuations can stress the PCM.
- Inspect and clean the PCM ground strap connection at the lower forward stud to ensure a solid ground.
- Always disconnect the battery and turn the ignition off before unplugging any PCM connectors to avoid voltage spikes.
- Address diagnostic trouble codes promptly; ignoring a code like P0606 can lead to further module damage.
- Protect the PCM connector seals from moisture and debris to prevent corrosion on the pins.
Frequently Asked Questions
How do I know if the PCM in my 2016 Dodge Dart 1.4L needs replacement?
Common signs include a no-start condition, stalling, misfire codes, or a P0606 internal processor fault. If you have ruled out other causes like sensors or wiring, the PCM may be at fault. A professional diagnostic scan can confirm.
Can I replace the PCM in my 2016 Dodge Dart myself?
Yes, if you have basic mechanical skills. The book time is 0.9 hours for the PCM. You must disconnect the battery and turn the ignition off before unplugging connectors.
