It continuously monitors data from sensors throughout the vehicle, adjusting fuel injection, ignition timing, and shift points to optimize performance and efficiency. Without a properly functioning PCM, your Lancer may struggle to start, run roughly, or even enter a failsafe mode that limits power. The module also plays a key role in emissions control, ensuring your vehicle meets regulatory standards. Over time, internal components may degrade due to heat, voltage spikes, or moisture intrusion, leading to erratic behavior or complete failure. If replacement becomes necessary, you\u2019ll need <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/mitsubishi-pcm-ecm-ecu-engine-computer\/lancer-engine-computers.html\">replacement engine computers for the Lancer<\/a> that are compatible with your vehicle\u2019s specifications. While the PCM is designed to last the life of the vehicle, electrical issues or manufacturing defects can sometimes shorten its lifespan, making it important to address symptoms as soon as they arise.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>In the 2012 Mitsubishi Lancer, the PCM is located in the engine bay, typically mounted near the firewall or on the driver\u2019s side fender well. Accessing it requires removing a protective cover or panel, which may involve unbolting a few fasteners. Once exposed, the module is secured with a connector and possibly a mounting bracket. Replacement involves disconnecting the battery, unplugging the wiring harness, and carefully removing the old unit. The new PCM is then installed in the same position, with the connector reattached and the battery reconnected. According to factory labor estimates, the entire removal and replacement process typically takes 0.9 hours. After installation, the module must undergo a relearn procedure to synchronize with the vehicle\u2019s systems, which adds another 0.5 hours of labor. Proper torque on mounting hardware and secure connector engagement are critical to prevent future issues.<\/p>\n<table style=\"width:100%;border-collapse:collapse;margin:18px 0;font-size:15px\">\n<tr>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Operation<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Configuration<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Book Time<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.9 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.9 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After replacing the PCM in your 2012 Mitsubishi Lancer, the vehicle requires a relearn procedure to ensure the new module communicates correctly with the engine and transmission systems.
