When it fails, the engine may not start, run poorly, or trigger warning lights. Replacement requires reprogramming with the vehicle&#8217;s VIN and mileage.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>The PCM controls engine and transmission functions in the 1999 Dodge Neon 2.0L.<\/li>\n<li>Failure often causes no-start, stalling, or erratic shifting.<\/li>\n<li>Replacement requires 0.5 hours labor plus 0.5 hours for a relearn procedure.<\/li>\n<li>Factory reprogramming uses a DRBIII scan tool to write the VIN and mileage.<\/li>\n<li>A pre-programmed replacement unit eliminates the need for dealer-level programming.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 1999 Dodge Neon 2.0L is experiencing intermittent stalling, hard starting, or a check engine light that won&#8217;t clear, the Powertrain Control Module (PCM) may be the culprit. This computer is the brain of your engine management system, controlling fuel injection, ignition timing, and emissions. Over time, internal components can fail due to heat, vibration, or electrical surges. Replacing the PCM is a straightforward repair, but it comes with a critical step: the new module must be programmed with your vehicle&#8217;s original VIN and mileage. Without that programming, the engine may not run correctly or may fail emissions tests. This guide explains what the PCM does, where it is located, how replacement works, and what you need to know about programming. You will also learn about common failure symptoms and how a pre-programmed replacement unit can save you time and money.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1999 Dodge Neon<\/h2>\n<p>The Powertrain Control Module (PCM) in your 1999 Dodge Neon 2.0L is a single computer that integrates both engine and transmission control functions. It receives data from sensors like the crankshaft position sensor, throttle position sensor, and oxygen sensors, then adjusts fuel injector pulse width, spark timing, and shift points accordingly. This module also manages idle speed, evaporative emissions, and the charging system. When the PCM fails, the engine may run in a default limp-home mode, often with reduced power and poor fuel economy. Because the PCM is specific to your Neon&#8217;s engine calibration, a replacement unit must be programmed with the vehicle&#8217;s VIN and mileage to match the immobilizer and emissions systems. For a reliable fix, consider <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/neon-engine-computers.html\">replacement engine computers for the 1999 Dodge Neon<\/a> that come pre-programmed to your vehicle&#8217;s specifications, eliminating the need for a dealer visit.<\/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 your 1999 Dodge Neon 2.0L is located in the engine compartment, typically mounted near the battery or on the driver-side inner fender. Replacement is a straightforward job: disconnect the battery, unbolt the module, remove the wiring harness connectors, and install the new unit. According to factory labor times, the PCM removal and replacement (R&amp;R) takes 0.5 hours. After installation, a relearn procedure is required, which also takes 0.5 hours. This relearn allows the PCM to adapt to the engine&#8217;s specific idle and fuel trim characteristics. Ensure the battery is fully charged before starting the relearn, as low voltage can interrupt the process. Always use a scan tool to verify that the new module communicates properly with the vehicle&#8217;s other systems.<\/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\/1999-dodge-neon-pcm-location-diagram.webp\" alt=\"1999 Dodge Neon PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 1999 Dodge 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 1999 Dodge 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>Disconnect<\/b> positive cable from battery.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> washer bottle neck.<\/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 the 2 40-way connector.<\/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\">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\">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<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After installing a new PCM in your 1999 Dodge Neon 2.0L, the factory procedure requires using a DRBIII scan tool to reprogram the module with the vehicle&#8217;s original VIN and mileage.
