When either unit fails, the engine may refuse to start, run erratically, or trigger diagnostic codes such as P0601 or P0606, indicating internal processor or communication faults.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM or ECM replacement typically requires about six tenths of an hour for removal and installation.<\/li>\n<li>Relearn procedures add roughly half an hour for each module after installation.<\/li>\n<li>Factory service bulletins call for reprogramming the PCM with the original VIN and mileage.<\/li>\n<li>Diagnostic codes P0601 and P0606 are common indicators of module internal failures.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2016 Dodge Journey experiences no\u2011start conditions, rough idle, or unexpected shifting, the powertrain control module or engine control module may be at fault. Understanding how these computers operate, where they sit, and what steps are needed after replacement can help you decide between a repair or a refurbished unit. This guide outlines the essential labor, programming requirements, and common symptoms so you can make an informed choice for your vehicle.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2016 Dodge Journey<\/h2>\n<p>The PCM in the 2016 Dodge Journey coordinates engine and transmission functions, translating sensor data into precise fuel and spark timing while also controlling shift points. The ECM focuses on engine-specific management, ensuring combustion efficiency and emissions compliance. Together they keep the powertrain running smoothly, and any internal fault can disrupt performance. Proper operation is vital for fuel economy and drivability, and <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/journey-engine-computers.html\">replacement powertrain control modules for the 2016 Dodge Journey<\/a> often require the same diagnostic procedures as the originals.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM and ECM are mounted within the engine compartment, accessible without extensive disassembly. Removing either unit follows the book\u2011time estimate of 0.6 hours for the 3.6L engine version. Installation mirrors the removal time, also listed as 0.6 hours. After the new module is in place, a relearn of the control strategy typically takes an additional 0.5 hours for the PCM and 0.5 hours for the ECM, ensuring the vehicle recognizes the replacement.<\/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\/2016-dodge-journey-pcm-location-diagram.webp\" alt=\"2016 Dodge Journey PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2016 Dodge Journey.<\/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 2016 Dodge Journey<\/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> and isolate the negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Unlock<\/b> and disconnect the 2 electrical connectors at the PCM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 4 bolts holding the PCM to the bracket and remove the PCM from the ve.<\/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\">0.6 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\">0.6 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 Reset<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.3 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\">0.6 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\">0.6 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>Factory service instructions require the use of a scan tool to reprogram the new PCM with the vehicle&#8217;s original VIN and mileage after installation.
