2019 Chevrolet Camaro 2.0L PCM/ECM Replacement Guide
The powertrain control module (PCM) or engine control module (ECM) in the 2019 Chevrolet Camaro 2.0L is the main computer that manages fuel injection, ignition timing, turbocharger boost, and emissions. Failure can cause no-start, stalling, misfire codes, or loss of communication with the scan tool.
Quick Summary
- PCM/ECM replacement book time is 1.4 hours; a relearn adds 0.5 hours and a reset adds 0.3 hours.
- Always turn the ignition off before disconnecting or connecting ECM connectors to prevent component damage.
- Factory service bulletins #PIP5375B and #PIP5597 address ECM programming errors and engine identification prompts.
- Common failure symptoms include no-start, stalling, misfire, and diagnostic trouble codes such as P0601 through P064F.
- Flagship One supplies VIN-programmed units that eliminate the need for a factory relearn or reset procedure.
If your 2019 Chevrolet Camaro 2.0L is experiencing a no-start, intermittent stalling, or check-engine light with module-related trouble codes, the powertrain control module (PCM) or engine control module (ECM) may be at fault. This guide covers what the module does, where it is located, the labor times involved in replacement, and the factory programming steps required after installation. You will also learn about common symptoms, relevant service bulletins, and how a pre-programmed replacement unit can simplify the repair. The information is based on published labor times and factory service information for this specific vehicle.
What the PCM Does in a 2019 Chevrolet Camaro
The powertrain control module (PCM) in the 2019 Chevrolet Camaro 2.0L is the central computer that controls the engine and transmission. It receives data from sensors such as the oxygen sensors, throttle position sensor, and crankshaft position sensor, then adjusts fuel delivery, ignition timing, and turbocharger boost pressure to optimize performance and emissions. The module also communicates with other control units over the CAN bus. When the PCM fails, the engine may not start, run poorly, or set internal diagnostic trouble codes. For this vehicle, replacement engine computers for the Camaro are available that come pre-programmed with the correct VIN and calibration, reducing downtime and avoiding the need for a dealer visit.
Where the PCM Is Located and What Replacement Involves
The PCM/ECM on the 2019 Chevrolet Camaro 2.0L is located in the engine compartment, typically mounted on the driver-side strut tower or near the air intake box. Replacement involves disconnecting the battery, removing the module from its bracket, and unplugging the wiring harness connectors. The factory caution states that the ignition must be off when installing or removing ECM connectors to prevent damage to the components. Book labor time for PCM or ECM removal and replacement is 1.4 hours. After installation, a relearn procedure takes 0.5 hours and a reset procedure takes 0.3 hours, if required. Access is straightforward but care is needed with the connector locks and mounting bolts.
How to Reach the PCM on the 2019 Chevrolet Camaro
- Disconnect the negative battery cable.
- Remove any debris from around the control module connector.
- Disconnect the electrical connectors.
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 | 1.4 hr |
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 1.4 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
Programming Requirements After Replacement
After installing a new PCM/ECM in the 2019 Chevrolet Camaro 2.0L, the factory procedure requires a relearn and sometimes a reset. The relearn (0.5 hours) synchronizes the module with the vehicle’s security system and learned adaptations. The reset (0.3 hours) clears any stored faults and initializes the module. Additionally, service bulletin #PIP5597 notes that during programming the technician may be prompted to input the engine identification number. Flagship One units arrive a VIN-programmed replacement unit so these steps are already completed, meaning you can install the module and start the engine without needing a scan tool or dealer visit.
Symptoms of a Failing PCM
A failing PCM/ECM in the 2019 Chevrolet Camaro 2.0L often causes a no-start condition where the engine cranks but does not fire. Intermittent stalling, rough idle, or misfire under load are also common. The check-engine light may illuminate with codes such as internal control module checksum error or other module-internal faults. You may also experience poor fuel economy, hesitation during acceleration, or a loss of communication with the scan tool. In some cases, the transmission may shift erratically or fail to shift because the PCM controls shift timing. If multiple unrelated codes appear, the module itself is often the root cause.
Module Trouble Codes on the 2019 Chevrolet Camaro
The following diagnostic trouble codes are documented for the PCM/ECM in the 2019 Chevrolet Camaro 2.0L. These internal module codes indicate a failure within the control unit itself rather than a sensor or circuit issue.

Factory Service Bulletins Worth Knowing
Two factory service bulletins apply to the 2019 Chevrolet Camaro 2.0L PCM/ECM. Bulletin #PIP5375B (dated June 11, 2018) addresses ECM programming errors that set codes E4491 or E4423. Bulletin #PIP5597 (dated October 8, 2018) notes that during ECM programming the technician may be prompted to input the engine identification number. Both bulletins are preliminary information and provide guidance for technicians when programming the module. Following these bulletins helps avoid programming failures and ensures the correct calibration is applied.

Protecting the PCM in Your 2019 Chevrolet Camaro
- Keep the battery and charging system in good condition; low voltage can damage the PCM/ECM.
- Inspect and clean ground connections and harness connectors annually, especially in salt-belt regions.
- Avoid jump-starting the vehicle with a running donor vehicle; use a battery charger instead.
- Address any check-engine light or trouble code promptly before it leads to module failure.
- Ensure connector seals are intact and the module is mounted securely to prevent moisture entry.
- Never disconnect or connect ECM connectors with the ignition on, as stated in the factory caution.
Frequently Asked Questions
What is the book labor time for PCM replacement on a 2019 Chevrolet Camaro 2.0L?
The published labor time for PCM or ECM removal and replacement is 1.4 hours. An additional 0.5 hours is allowed for a relearn procedure, and 0.3 hours for a reset if needed. These times are from the factory labor guide.
Can I install a used PCM from a salvage yard in my 2019 Camaro 2.0L?
A used PCM will need to be programmed with your vehicle’s VIN and calibration, which requires a dealer-level scan tool. The factory relearn and reset procedures are also necessary. A pre-programmed unit from Flagship One avoids these steps and is often a more reliable option.
What does trouble code P0601 mean on a 2019 Chevrolet Camaro 2.0L?
P0601 is an internal control module checksum error. It indicates that the PCM/ECM has detected a fault in its own memory. This code typically requires module replacement because the internal processor or memory chip has failed.
When your 2019 Chevrolet Camaro 2.0L needs a new PCM/ECM, you have two main options: have a shop perform the replacement and programming, or install a pre-programmed unit yourself. The factory book time for the job is 1.4 hours plus programming, but a VIN-programmed module from Flagship One eliminates the need for a relearn or reset, saving time and diagnostic fees. This approach is especially practical for the Camaro’s 2.0L turbo engine, where correct calibration is critical for performance and emissions.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2019 Chevrolet Camaro with a lifetime warranty, free shipping and no core charge. The full Chevrolet Camaro module lineup covers other engine configurations as well.
Final Thoughts
The PCM/ECM in the 2019 Chevrolet Camaro 2.0L is a vital component that controls engine and transmission operation. When it fails, symptoms like no-start, stalling, and internal trouble codes appear. Replacement requires 1.4 hours of labor plus programming steps, but a pre-programmed unit from Flagship One simplifies the repair. Consider this option to get your Camaro back on the road quickly.
