When it fails, you may experience no-start conditions, stalling, or diagnostic trouble code P0606, indicating an internal processor fault.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>Replacing the PCM\/ECM on a 2013 Tundra 5.7L has a book labor time of 0.5 hours for removal and installation.<\/li>\n<li>A separate 0.5-hour relearn procedure is required after the new module is installed.<\/li>\n<li>Access to the module requires removing the connector holder block.<\/li>\n<li>An internal module fault may set diagnostic trouble code P0606.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 2013 Toyota Tundra 5.7L is experiencing starting issues, stalling, or a check engine light, the powertrain control module (PCM) or engine control module (ECM) could be at fault. This module is the brain of the engine and transmission management system. This guide explains what the module does, where it is located, how replacement is performed, and what programming steps are needed. You will also learn about common symptoms and the specific trouble code P0606 that points to an internal module failure. 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 2013 Toyota Tundra<\/h2>\n<p>The PCM\/ECM in your 2013 Toyota Tundra 5.7L is a single computer that controls both engine and transmission functions. It receives input from sensors such as the crankshaft position sensor, throttle position sensor, and oxygen sensors, then adjusts fuel delivery, ignition timing, and shift points accordingly. This module also monitors system health and stores diagnostic trouble codes when something goes wrong. When the module itself fails, it can cause a range of drivability problems because it cannot process sensor data correctly. For this reason, <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/tundra-engine-computers.html\">replacement PCMs for the Tundra<\/a> are often needed when internal faults like P0606 appear. The module is critical for maintaining performance, fuel economy, and emissions compliance.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM\/ECM on a 2013 Toyota Tundra 5.7L is mounted in the engine compartment, typically near the firewall on the passenger side. To access it, you must first remove the connector holder block that secures the wiring harness connectors to the module. The book labor time for removing and replacing the module is 0.5 hours. After installation, a separate 0.5-hour relearn procedure is required to synchronize the module with the vehicle&#8217;s systems. No special torque specifications are provided for the mounting hardware, but care should be taken to reconnect all connectors firmly and ensure the holder block is properly seated.<\/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\/2013-toyota-tundra-pcm-service-figure.webp\" alt=\"2013 Toyota Tundra PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2013 Toyota Tundra.<\/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 2013 Toyota Tundra<\/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> connector holder block.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Raise<\/b> the 2 levers while pushing the locks on the 2 levers.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 2 connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 4 bolts and ECM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> ECM gasket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the tape of the gasket without using bladed objects.<\/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\">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\">0.5 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\">0.5 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<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After installing a new PCM\/ECM in a 2013 Toyota Tundra 5.7L, the factory procedure requires a relearn process that takes 0.5 hours.
