Failure often manifests as misfires, hesitation, or a MIL. A faulty PCM can disrupt sensor readings and fuel delivery.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM relearn takes 0.5 hours.<\/li>\n<li>PCM R&amp;R also 0.5 hours.<\/li>\n<li>Engine Control Module relearn and R&amp;R each 0.5 hours.<\/li>\n<li>PATS reprogramming is required.<\/li>\n<li>TSB 06-12-10 addresses MIL with P0607.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When your 2006 Lincoln Mark LT displays a check engine light and you encounter codes such as P0607, it is often related to the Powertrain Control Module. Understanding how to properly relearn or replace this module can restore proper engine performance and eliminate lingering trouble codes. This guide outlines the essential steps, labor estimates, and post\u2011replacement programming that ensures your vehicle runs smoothly.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2006 Lincoln Mark LT<\/h2>\n<p>The Powertrain Control Module in the 2006 Lincoln Mark LT is responsible for coordinating engine timing, fuel injection, and transmission shifts. <a href=\"https:\/\/www.fs1inc.com\/ford-lincoln-mercury\/lincoln-pcm-ecm-ecu-engine-computer\/mark-lt-engine-computers.html\">replacement engine computers for the 2006 Lincoln Mark LT<\/a> This module interprets sensor data and sends commands to actuators, making its reliability vital for smooth acceleration and fuel efficiency. A malfunctioning PCM can lead to erratic throttle response or a sudden loss of power.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM is located under the passenger side seat, accessed by removing the seat cushion and the lower dash panel. The labor book time for a relearn is 0.5 hours, and for a replace-and-relearn it is also 0.5 hours. The procedure involves disconnecting the battery, removing the PCM, installing the new unit, and performing a relearn cycle.<\/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\/2006-lincoln-mark-lt-pcm-service-figure.webp\" alt=\"2006 Lincoln Mark LT PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2006 Lincoln Mark LT.<\/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 2006 Lincoln Mark LT<\/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 powertrain control module (PCM) electrical connectors (3 required).<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the PCM bolt (4 required).<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the PCM bracket bolts.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the PCM 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\">0.5 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 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, the factory requires a relearn of the passive anti\u2011theft system.
