Failure of these computers can trigger stalling, no\u2011start conditions, and diagnostic trouble codes such as P0601 or P0606, often requiring re\u2011learn procedures or replacement.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM\/ECM relearn takes about half an hour for most tasks.<\/li>\n<li>Ground strap three attaches to the low forward stud.<\/li>\n<li>Never disconnect PCM connectors with the key on.<\/li>\n<li>New modules must be VIN\u2011programmed to avoid DTCs.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2014 Dodge Avenger experiences persistent MIL illumination or erratic engine behavior, the powertrain and engine control modules become the focus of diagnosis. Understanding how these computers operate, where they sit, and what factory procedures demand can help you decide between repair and replacement. This guide outlines the key facts, typical labor times, and safety cautions so you can approach the job with confidence.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2014 Dodge Avenger<\/h2>\n<p>The PCM and ECM in the 2014 Dodge Avenger coordinate fuel injection, ignition timing, and transmission control to keep the powertrain running smoothly. They store calibration data and monitor sensor inputs, issuing codes when parameters fall outside limits. Proper operation is essential for performance and emissions compliance. The vehicle relies on <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/avenger-engine-computers.html\">replacement PCM for Avenger<\/a> to maintain these functions after a failure.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM is secured with a ground strap labeled three, which attaches to the lowest forward stud on the engine block. Access typically requires removal of the intake assembly to reach the module. Labor times listed in the service guide indicate 0.3 hours for a 3.6L PCM removal and replacement, while the ECM removal for the same engine also averages 0.3 hours. Follow the factory caution to keep the ignition key off and disconnect the battery before handling any connectors.<\/p>\n<figure style=\"margin:22px auto;text-align:center;max-width:720px\"><img decoding=\"async\" style=\"max-width:100%;height:auto;border:1px solid #e2e6ec;border-radius:8px\" src=\"https:\/\/www.fs1inc.com\/blog\/wp-content\/uploads\/2026\/07\/2014-dodge-avenger-pcm-service-figure.webp\" alt=\"2014 Dodge Avenger PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2014 Dodge Avenger.<\/figcaption><\/figure>\n<div style=\"background:#f7f9fc;border:1px solid #e2e8f2;border-radius:10px;padding:18px 24px;margin:18px 0\">\n<h3 style='margin-top:0'>How to Reach the PCM on the 2014 Dodge Avenger<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the Powertrain Control Module (PCM) electrical connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the three nuts.<\/li>\n<\/ol>\n<p style='margin:10px 0 0 0'><em>Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.<\/em><\/p>\n<\/div>\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 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\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">2.4L<\/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\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">3.6L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.3 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\">2.4L<\/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\">3.6L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.3 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After installing a new PCM or ECM, the factory procedure calls for a scan tool to reprogram the unit with the original VIN and mileage, preventing a diagnostic trouble code from setting.
