If you own a 2016 Dodge Challenger with the 5.7L engine and are experiencing drivability issues, the Powertrain Control Module (PCM) may be at fault. This module is the central computer that controls engine timing, fuel delivery, and transmission operation. When it fails, symptoms like no-start, stalling, or check-engine lights with specific codes can appear. This guide explains what the PCM does in your Challenger, where it is located, what replacement involves according to factory labor times, and the critical programming steps required after installation. You will also learn about a related safety recall and how to address internal trouble codes. Understanding these details helps you make an informed decision about repairing or replacing the module.
What the PCM Does in a 2016 Dodge Challenger
The Powertrain Control Module (PCM) in your 2016 Dodge Challenger 5.7L is a single unit that combines engine and transmission control. It receives data from sensors throughout the vehicle and adjusts ignition timing, fuel injection, and shift points to optimize performance and emissions. The PCM also monitors system health and stores diagnostic trouble codes when it detects a fault. Because it manages both the engine and transmission, a failing PCM can cause a wide range of symptoms from rough idling to complete no-start. If you need a replacement, you can find replacement PCMs for the Challenger that are built to match the original specifications. Choosing the correct module ensures your vehicle continues to run smoothly and meet emissions standards.
Where the PCM Is Located and What Replacement Involves
The PCM in the 2016 Dodge Challenger 5.7L is typically located in the engine compartment, often near the battery or on the driver-side fender well. According to factory labor times, removing and replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM) is allotted 0.6 hours. A PCM or ECM relearn procedure is listed at 0.5 hours, and an ECM reset is 0.3 hours. The factory notes that if a new PCM is installed, it must be programmed with the original Vehicle Identification Number (VIN) and mileage. Additionally, the service information directs you to Section 08 – Electrical/8E – Electronic Control Modules for module programming details. A factory caution advises verifying the vehicle’s VIN and software level in the PCM when diagnosing concerns. Access to the module may require removing some covers or components, but the book time reflects a straightforward replacement.
How to Reach the PCM on the 2016 Dodge Challenger
- Disconnect and isolate the negative battery cable.
- Remove the hood ajar switch.
- Remove the Powertrain Control Module (PCM) retaining bolt.
- Disconnect the PCM electrical connectors.
- Remove the PCM from the vehicle.
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 Relearn | All configurations | 0.5 hr |
| Powertrain Control Module R&R | All configurations | 0.6 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
| Engine Control Module R&R | All configurations | 0.6 hr |
Programming Requirements After Replacement
After installing a new PCM in your 2016 Dodge Challenger 5.7L, the factory procedure requires programming the module with the original Vehicle Identification Number (VIN) and current mileage. This step is essential for the module to communicate correctly with the vehicle’s anti-theft system and other controllers. The service manual references Section 08 – Electrical/8E – Electronic Control Modules for the specific programming process. To simplify this, you can choose a VIN-programmed replacement unit from Flagship One that arrives with the correct VIN and mileage already set. This eliminates the need for a dealership visit or specialized scan tool, saving time and ensuring the module is ready to install and drive.
Symptoms of a Failing PCM
A failing PCM in your 2016 Dodge Challenger 5.7L can produce several noticeable symptoms. The engine may crank but not start, or it might start and stall shortly after. You could experience intermittent misfires, rough idle, or hesitation during acceleration. Transmission shifting may become erratic or harsh. The check engine light often illuminates, and a scan tool may show communication errors with the module. One common internal fault is internal control module fault P0601, which indicates a memory checksum error within the PCM. Other symptoms include poor fuel economy, surging, or the vehicle entering a limp-home mode. If you notice any of these issues, diagnosing the PCM early can prevent further drivability problems.
Module Trouble Codes on the 2016 Dodge Challenger
The following diagnostic trouble codes are documented for the PCM in the 2016 Dodge Challenger 5.7L. These codes indicate internal module faults that may require replacement or reprogramming.
