This guide explains what the PCM does, where it is located, and what replacement involves. You will learn about common failure symptoms, the factory programming requirement, and relevant service bulletins. Understanding these details helps you make an informed decision about repair or replacement.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2011 Chrysler 300<\/h2>\n<p>The Powertrain Control Module (PCM) in your 2011 Chrysler 300 3.6L is the central computer that controls engine and transmission operation. It processes sensor inputs and adjusts fuel delivery, ignition timing, and shift points to optimize performance and emissions. When the PCM fails, it can cause a range of drivability problems. If you need a replacement, consider <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/300m-engine-computers.html\">replacement PCMs for the 2011 Chrysler 300<\/a> that are pre-programmed to avoid additional steps. The PCM also stores diagnostic trouble codes that help pinpoint issues. Its proper function is critical for reliable operation.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The Powertrain Control Module (PCM) in your 2011 Chrysler 300 3.6L is located in the engine compartment. Replacement book time is 0.6 hours for removal and installation, and a PCM relearn takes 0.5 hours. An ECM reset is listed at 0.3 hours. If a new PCM is installed, it must be programmed with the original Vehicle Identification Number (VIN) and mileage. Access typically involves removing the air intake duct and possibly the battery tray. Ensure the ignition is off and the battery is disconnected before handling the module.<\/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\/2011-chrysler-300-pcm-location-diagram.webp\" alt=\"2011 Chrysler 300 PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2011 Chrysler 300.<\/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 2011 Chrysler 300<\/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>Remove<\/b> the engine cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the wiper arm linkage.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> bolts and the strut support brace.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the Powertrain Control Module (PCM) wire harness connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the crash sensor wire harness connector from inner fender.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> bolt and the PCM with mounting bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> nuts and the PCM from mounting bracket.<\/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\">All configurations<\/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\">All configurations<\/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 procedure requires that a new PCM be programmed with the original VIN and mileage before the vehicle can start.

You may also notice poor fuel economy or erratic shifting. A professional scan tool can confirm if the PCM is not communicating.<\/p>\n<h3>Can I replace the PCM in my 2011 Chrysler 300 3.6L myself?<\/h3>\n<p>Yes, if you have basic mechanical skills. The PCM is in the engine compartment and replacement book time is 0.6 hours. However, a new PCM must be programmed with the VIN and mileage, which typically requires a dealer or a pre-programmed unit from a supplier like Flagship One.<\/p>\n<h3>What is the difference between a PCM and an ECM in my 2011 Chrysler 300 3.6L?<\/h3>\n<p>In this vehicle, the PCM (Powertrain Control Module) controls both engine and transmission. An ECM (Engine Control Module) would only control the engine. The 3.6L uses a PCM, so the terms are often used interchangeably, but the PCM is the correct module.<\/p>\n<\/div>\n<div class=\"info-section\">\n<p>When your 2011 Chrysler 300 3.6L needs a new PCM, you have options: repair the existing module or replace it with a refurbished unit. A refurbished PCM from a trusted supplier can be a cost-effective solution, especially if it arrives pre-programmed with your VIN. This avoids dealer programming fees and gets your vehicle back on the road faster.<\/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\/media\/wysiwyg\/googleshop\/chrysler1gray1black\/chrysler-grayblack-large1.jpg\" alt=\"Refurbished VIN-programmed PCM for the 2011 Chrysler 300\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">A refurbished, VIN-programmed replacement PCM for the 2011 Chrysler 300 from Flagship One.<\/figcaption><\/figure>\n<p>Flagship One stocks a <a href=\"https:\/\/www.fs1inc.com\/2011-chrysler-300-3-6l-engine-computer-pcm-ecm-ecu-programmed-plug-play.html\"><b>refurbished, VIN-programmed PCM for the 2011 Chrysler 300<\/b><\/a> with a lifetime warranty, free shipping and no core charge.
