Those symptoms can often point to the Powertrain Control Module, the central brain that coordinates fuel, ignition, and shift timing. Understanding how this module works, why it can fail, and what a replacement involves helps you make an informed decision. By the end of this guide you\u2019ll know the key signs of PCM trouble, the precise steps to replace it, and how a pre\u2011programmed unit from Flagship One can save you time and hassle.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1996 Plymouth Neon<\/h2>\n<p>The Powertrain Control Module (PCM) in the 1996 Plymouth Neon interprets sensor data from the engine and transmission, adjusting fuel injection, ignition timing, and shift points to maintain performance and emissions compliance. This module works closely with the Engine Control Module (ECM) to share critical data. When the PCM stops responding or outputs incorrect parameters, the vehicle may misfire, stall, or fail to start. <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/plymouth-pcm-ecm-ecu-engine-computer\/neon-engine-computers.html\">Replacement Powertrain Control Module for 1996 Plymouth Neon<\/a> is a direct substitute that matches the original PCM\u2019s architecture and electrical interface.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM sits beneath the steering column, accessible by removing the dashboard trim panel. A technician will disconnect the battery, remove the mounting screws, and lift the module out. Replacement takes roughly 0.5\u20130.6 hours, depending on whether the vehicle is in a van or car configuration. The new unit is then bolted in, reconnected, and the battery is reattached.<\/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\/1996-plymouth-neon-pcm-location-diagram.webp\" alt=\"1996 Plymouth Neon PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 1996 Plymouth Neon.<\/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 1996 Plymouth Neon<\/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> negative cable from battery.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> positive cable from battery.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the washer bottle neck from the rubber grommet.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> screws attaching PCM to body.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Lift<\/b> PCM up and disconnect two 40-way connectors.<\/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\">Van<\/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\">Car<\/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\">Van<\/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 R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Car<\/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\">Van<\/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\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Car<\/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\">Van<\/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\">Car<\/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 procedure typically requires a reprogramming step to update powertrain data and calibrate the module for the specific vehicle.
