A failure typically results in loss of engine drive, erratic idle, or diagnostic trouble codes such as P0606, indicating internal processor issues.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>ECM reset may resolve intermittent glitches in about 0.3\u202fhours.<\/li>\n<li>Full removal and reinstall generally requires 0.8\u202fhours of labor.<\/li>\n<li>Factory removal accesses the module next to the air\u2011cleaner assembly.<\/li>\n<li>Flagship One units arrive pre\u2011programmed, eliminating post\u2011install steps.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When the engine control module in your 2019 Lexus NX300 begins to misbehave, the vehicle may hesitate, stall, or refuse to start. Understanding how the ECM functions, where it sits, and what the factory recommends for removal and re\u2011learn can help you decide between a repair or a replacement. This guide walks you through the module\u2019s role, access steps, required programming, and typical symptoms so you can make an informed choice.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2019 Lexus NX300<\/h2>\n<p>In the 2019 Lexus NX300 the engine control module serves as the brain that processes sensor data to command fuel injection, spark timing, and emission controls. Its proper operation is essential for smooth acceleration and emissions compliance. When the unit fails, the vehicle may lose driveability and trigger diagnostic codes. For those seeking alternatives, <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/lexus-ecm-pcm-ecu-engine-computer\/nx300-engine-computers.html\">replacement engine computers for the 2019 Lexus NX300<\/a> provide a direct swap without modifying wiring.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The ECM is positioned beside the air\u2011cleaner assembly, reachable after removing the battery cables, clamp sub\u2011assembly, insulator, battery, and the air\u2011cleaner cap. Labor times list 0.8\u202fhours for removal and reinstall, while a reset or relearn adds 0.3 to 0.5\u202fhours. Follow the factory caution to wait after switching off the engine before disconnecting the battery cables.<\/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\/2019-lexus-nx300-ecm-location-card.webp\" alt=\"2019 Lexus NX300 PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2019 Lexus NX300 (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 Lexus NX300<\/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> cable from negative battery terminal.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> cable from positive battery terminal.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> BATTERY CLAMP SUB-ASSEMBLY Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> BATTERY INSULATOR Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> BATTERY Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> air cleaner cap sub-assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the intake mass air flow meter sub-assembly connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Detach<\/b> the 2 clips, loosen the hose clamp and remove the air cleaner cap sub-assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> air cleaner case sub-assembly.<\/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 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\">0.8 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\">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\">0.8 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 unit, the factory calls for an ECM relearn procedure lasting about half an hour.
