A malfunction typically triggers the P0606 code and can lead to loss of power, stalling, or communication failure with diagnostic tools.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM removal generally requires about 0.7\u202fhours of labor.<\/li>\n<li>ECM replacement adds roughly 0.5\u202fhours for removal and another 0.3\u202fhours for reset.<\/li>\n<li>Both modules demand VIN registration and throttle\u2011body initialization after installation.<\/li>\n<li>Factory procedure also calls for a reset of transmission memory when the ECM is changed.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If you are facing a P0606 code or erratic power\u2011train behavior in your 2013 Toyota Tacoma X\u2011Runner, the issue often points to the PCM or ECM. Understanding what these computers do, how they are accessed, and the steps required after replacement can help you decide between a new factory unit or a refurbished option. This guide walks you through the essential facts 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 2013 Toyota Tacoma X-Runner<\/h2>\n<p>The powertrain control module in the 2013 Toyota Tacoma X\u2011Runner oversees the interaction between the engine and transmission, regulating fuel injection, ignition timing, and shift timing. The engine control module performs similar duties focused on engine operation, interpreting sensor data to keep the engine running smoothly. Together, they ensure optimal performance and emissions compliance. <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/tacoma-x-runner-engine-computers.html\">replacement engine computers for the 2013 Toyota Tacoma X\u2011Runner<\/a> These units are critical because any fault can disrupt power delivery and cause diagnostic trouble codes.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>Access to both the PCM and ECM in the 2013 Tacoma X\u2011Runner is achieved by removing the cable that connects to the vehicle\u2019s negative battery lead. Once the cable is cleared, the modules sit within the engine compartment, secured with bolts that typically require no special torque specifications. Removing the PCM generally takes about 0.7\u202fhours, while extracting the ECM is listed at 0.5\u202fhours. Reinstallation follows the same steps in reverse, and a brief reset procedure of 0.3\u202fhours may be needed for the ECM after it is 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-tacoma-x-runner-pcm-location-diagram.webp\" alt=\"2013 Toyota Tacoma X-Runner PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2013 Toyota Tacoma X-Runner.<\/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 Tacoma X-Runner<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> INSTRUMENT PANEL FINISH PANEL SUB-ASSEMBLY LOWER RH More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 4 connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 bolts and nut, then remove the ECM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> ECM bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 3 screws, then remove the ECM bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> ECM bracket no.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 screws, then remove the ECM bracket No.<\/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 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\">0.7 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<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\">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<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After installing a new or rebuilt unit, the factory procedure calls for VIN registration, throttle\u2011body initialization, and a reset of transmission memory if the ECM is replaced.
