When it fails, the vehicle may not start, run poorly, or trigger a check engine light. The module is located next to the air cleaner assembly.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>The PCM is located next to the air cleaner assembly and requires 0.6 hours of labor to remove and replace on the 2.4L engine.<\/li>\n<li>After replacement, the factory procedure demands a scan-tool reprogram with the vehicle&#8217;s original VIN and mileage, a 0.5-hour relearn step.<\/li>\n<li>A stored trouble code P0601 indicates an internal control module fault that often requires PCM replacement.<\/li>\n<li>Flagship One supplies pre-programmed units that arrive with the correct VIN and mileage already set, eliminating the post-install programming step.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 2019 Dodge Journey 2.4L is experiencing no-start conditions, erratic shifting, or a check engine light with code P0601, the Powertrain Control Module (PCM) may be the root cause. This guide explains what the PCM does in your Journey, where it is located, what the factory replacement procedure involves, and how a pre-programmed replacement unit can simplify the repair. You will learn the book labor times, the critical programming requirement, and common symptoms that point to a failing module. Understanding these details helps you make an informed decision about repairing or replacing the PCM.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2019 Dodge Journey<\/h2>\n<p>The Powertrain Control Module (PCM) in the 2019 Dodge Journey 2.4L is the primary electronic brain that coordinates engine and transmission operation. It receives sensor inputs for throttle position, crankshaft speed, oxygen levels, and more, then adjusts fuel injector pulse width, ignition timing, and transmission shift patterns to keep the vehicle running efficiently. Because the 2.4L engine relies on precise electronic control for emissions and drivability, a failing PCM can cause hard starting, stalling, poor fuel economy, or transmission slipping. When the module fails internally, the only reliable fix is to replace it with a new or refurbished unit. For this reason, <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/journey-engine-computers.html\">replacement engine computers for the Journey<\/a> are a common solution when diagnostic trouble codes like P0601 appear and other causes have been ruled out. The PCM is vehicle-specific and must be programmed with the Journey&#8217;s original VIN and mileage to function correctly.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What Replacing the PCM Involves<\/h2>\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\/2019-dodge-journey-ecm-location-card-1.webp\" alt=\"2019 Dodge Journey PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2019 Dodge Journey (reference).<\/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 2019 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>Remove<\/b> the air cleaner body.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Unlock<\/b> and disconnect the electrical connectors from the PCM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the fasteners.<\/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 information for the 2019 Dodge Journey 2.4L states that after installing a new PCM, you must use a scan tool to reprogram the module with the vehicle&#8217;s original Identification Number (VIN) and the vehicle&#8217;s original mileage. This step is critical because the PCM will not operate the engine or transmission correctly without those parameters. The relearn procedure is listed at 0.5 hours of labor. Flagship One eliminates this post-install programming step by supplying <a href=\"https:\/\/www.fs1inc.com\/2019-dodge-journey-2-4l-pcm-engine-computer-ecm-ecu-programmed-plug-play.html\">a VIN-programmed replacement unit<\/a> that arrives with the correct VIN and mileage already loaded. This means you can install the module and, after a brief relearn, have the vehicle running without needing a factory-level scan tool or a trip to the dealer.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>When the PCM begins to fail in a 2019 Dodge Journey 2.4L, you may notice a no-start condition where the engine cranks but does not fire, or intermittent stalling that leaves you stranded. The check engine light often illuminates with a stored <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\">internal control module fault<\/a> that indicates the PCM has detected an internal error. Other common symptoms include rough idle, misfire codes that persist after replacing spark plugs and coils, erratic transmission shifting, and a complete loss of communication with a scan tool. Because the PCM controls both engine and transmission functions, a failure can mimic problems in other systems. If you have ruled out wiring, sensors, and actuators, the PCM itself is a likely suspect.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Module Trouble Codes on the 2019 Dodge Journey<\/h2>\n<p>The following trouble codes are stored internally within the PCM and indicate specific failures that point to the module itself rather than external components.
