When it fails, the vehicle can exhibit rough idle, loss of power, or erratic shifting.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM swap time: 0.5 hours for relearn, 0.6 hours for full R&amp;R.<\/li>\n<li>Unit is located behind the console and in the right kick panel area.<\/li>\n<li>Replacement requires removing the console and glove box.<\/li>\n<li>After installation, the unit is factory\u2011programmed to your VIN.<\/li>\n<li>Common failure symptoms include stalling and misfire codes.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>You\u2019ve noticed your 1993 Honda del Sol hesitating on acceleration or turning the key gives a weak engine response. These issues often stem from the vehicle\u2019s Powertrain Control Module, the brain that coordinates engine and transmission functions. This guide explains what the PCM does in your del Sol, where it sits, how to replace it, and what you can do to keep it running smoothly. By the end, you\u2019ll know whether a repair or a refurbished replacement is right for your vehicle and how to get the job done efficiently.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1993 Honda del Sol<\/h2>\n<p>In the 1993 Honda del Sol, the PCM receives inputs from the engine sensors and decides how much fuel to inject, when to advance ignition timing, and when to shift gears. It also monitors emissions parameters and communicates with the transmission control. If the PCM develops a fault, the engine may misfire, the vehicle may stall, or the transmission may shift erratically. This can lead to poor fuel economy and reduced performance. <a href=\"https:\/\/www.fs1inc.com\/honda-ecm-pcm-ecu-engine-computer\/del-sol-engine-computers.html\">1993 Honda del Sol PCM Replacement<\/a> The module\u2019s health is critical for maintaining the vehicle\u2019s drivability 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 in the 1993 Honda del Sol is located behind the console and in the right kick panel area when the glove box is removed. To replace it, you first remove the console, then lift the glove box to access the unit. The book time for a relearn procedure is 0.5 hours, while a full remove and replace takes 0.6 hours. After removal, the new unit is installed in the same position, and the console and glove box are reassembled.<\/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\/1993-honda-del-sol-ecm-location-card-1.webp\" alt=\"1993 Honda del Sol PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 1993 Honda del Sol (reference).<\/figcaption><\/figure>\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\">Civic<\/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\">Civic del Sol<\/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\">Civic<\/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\">Civic del Sol<\/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\">Civic<\/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\">Civic del Sol<\/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>Once the new PCM is installed, the factory procedure requires a relearn of the engine and transmission parameters.
