The PCM/ECM in your 2011 Mitsubishi Lancer Evolution 2.0L is the main computer controlling engine timing, fuel injection, and boost pressure. Failure can cause drivability issues, check engine light, and code P0606. Replacement requires programming to match your vehicle’s VIN.
If you own a 2011 Mitsubishi Lancer Evolution with the 2.0L turbocharged engine, you rely on a single electronic brain to manage fuel delivery, ignition timing, and boost control. That brain is the Powertrain Control Module (PCM) or Engine Control Module (ECM)—terms often used interchangeably for this vehicle. When this module begins to fail, the car may exhibit erratic behavior, from intermittent stalling to a complete no-start condition. The check engine light may illuminate with code P0606, signaling an internal processor fault. Understanding what the PCM/ECM does, how to recognize its failure, and what replacement involves can save you time and frustration. This guide covers the symptoms, the replacement process using factory book times, and the critical programming step that ensures the module communicates correctly with your Lancer Evolution. You will also learn how Flagship One’s pre-programmed units simplify the repair by eliminating the need for a dealer visit or specialized scan tool.
The PCM/ECM in your 2011 Mitsubishi Lancer Evolution 2.0L is the central computer that interprets sensor inputs and controls actuators to keep the engine running efficiently. It manages fuel injector pulse width, ignition coil firing, variable valve timing, and the turbocharger wastegate solenoid. Because the Lancer Evolution is a high-performance vehicle, the PCM/ECM also monitors knock sensors and adjusts timing to prevent detonation under boost. It communicates with other modules via the CAN bus, including the ABS and SRS systems. When the module fails, the engine may lose these critical controls, leading to poor performance or a no-start. Replacement requires a unit that is replacement PCM/ECM for the Lancer Evolution specifically programmed to your vehicle’s VIN to ensure proper immobilizer and emissions functions. Without correct programming, the car may not start or may run poorly. The module is designed to withstand underhood temperatures and vibration, but electrical surges or moisture can damage its internal circuitry.
Replacement of the PCM/ECM in your 2011 Lancer Evolution has a book time of 0.9 hours. The procedure involves disconnecting the battery, removing the module from its mounting, and transferring any necessary brackets. After installation, a relearn procedure is required, taking an additional 0.5 hours. This relearn typically involves using a scan tool to reset adaptive values and synchronize the module with the vehicle’s immobilizer system. While the exact location of the module is not specified in the available labor facts, it is commonly found in the engine bay or behind the glove box on Mitsubishi models. Ensure the battery is disconnected before handling any connectors to avoid short circuits. The mounting bolts should be tightened to factory specifications, though specific torque values are not provided here.
| 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 |
After installing a new or replacement PCM/ECM in your 2011 Lancer Evolution, the factory procedure requires a relearn process that takes 0.5 hours. This step is necessary to calibrate the module to the vehicle’s specific engine and transmission parameters, as well as to pair it with the immobilizer system. Without this relearn, the engine may not start or may run with reduced performance. Flagship One eliminates this post-installation step by providing a VIN-programmed replacement unit that arrives ready to install. The module is pre-loaded with the correct software and immobilizer data for your Lancer Evolution, so you can simply install it, reconnect the battery, and start the engine. This saves you the time and expense of a dealer visit or the need for a professional scan tool. The 0.5-hour relearn is already completed during the programming process at Flagship One’s facility.
When the PCM/ECM begins to fail in your 2011 Mitsubishi Lancer Evolution, you may notice a range of drivability issues. The engine may crank but not start, or it may start and then stall shortly after. You might experience intermittent misfires, rough idle, or a sudden loss of power during acceleration. The check engine light will likely illuminate, and a scan tool may retrieve code internal control module fault indicating an internal processor error. Other symptoms include the engine running in a reduced power mode (limp mode), poor fuel economy, or the cooling fan running constantly. Communication with the scan tool may be lost entirely, suggesting a complete module failure. Because the Lancer Evolution relies heavily on the PCM/ECM for boost control, a failing module can also cause overboost or underboost conditions, leading to hesitation or surging. If you experience any of these issues, it is important to diagnose the module promptly to avoid secondary damage to sensors or actuators.
The following internal trouble code is documented for the PCM/ECM in your 2011 Mitsubishi Lancer Evolution 2.0L. This code indicates a fault within the module itself rather than a sensor or circuit issue.
| Code | Meaning | Full Guide |
|---|---|---|
| P0606 | Module processor failure | Full P0606 guide → |
Code P0606 indicates an internal fault within the PCM/ECM itself. This could be a processor error, memory corruption, or a voltage regulation issue. It often requires module replacement or reprogramming to resolve.
Driving with a failing PCM/ECM is not recommended. The engine may stall unexpectedly, lose power, or enter limp mode, which can be dangerous in traffic. Continued operation may also cause damage to other components like the catalytic converter.
The book time for PCM/ECM replacement is 0.9 hours, plus an additional 0.5 hours for the relearn procedure. However, with a pre-programmed unit from Flagship One, the relearn step is already completed, reducing total installation time.
Yes, the factory procedure requires a relearn that takes 0.5 hours to synchronize the module with the immobilizer and adaptive values. Flagship One provides units that are pre-programmed with your VIN, so no further programming is needed.
Common symptoms include no-start, stalling, misfire codes, loss of communication with a scan tool, and the check engine light with code P0606. You may also notice erratic boost control or the engine running in limp mode.
When your 2011 Lancer Evolution’s PCM/ECM fails, you have two main options: have a dealer repair the original module or replace it with a refurbished unit. Repairing the original may be possible if the damage is limited, but replacement often provides a more reliable long-term solution. Flagship One offers refurbished PCM/ECM units that are pre-programmed to your vehicle’s VIN, eliminating the need for a dealer visit and the 0.5-hour relearn. This model-specific approach ensures a direct fit and quick return to the road.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2011 Mitsubishi Lancer Evolution with a lifetime warranty, free shipping and no core charge. The full Mitsubishi Lancer Evolution module lineup covers other engine configurations as well.
The PCM/ECM in your 2011 Mitsubishi Lancer Evolution 2.0L is a critical component that controls engine performance and drivability. Recognizing symptoms like code P0606 and understanding the replacement process—including the 0.9-hour book time and required relearn—helps you make an informed repair decision. Flagship One’s VIN-programmed units simplify the job by removing the post-installation programming step, getting your Evolution back to full power sooner.
