The 12+ Van 84 codes are a series of diagnostic trouble codes used in the automotive industry to identify and troubleshoot issues with vehicles. These codes are part of the On-Board Diagnostics (OBD) system, which is a standardized system used to monitor and diagnose problems with a vehicle's engine and other systems. In this article, we will explore the 12+ Van 84 codes, their meanings, and how to use them for easy troubleshooting.
Introduction to 12+ Van 84 Codes
The 12+ Van 84 codes are a subset of the OBD-II codes, which are used in vehicles manufactured after 1996. These codes are used to identify problems with the vehicle’s powertrain, transmission, and other systems. The codes are typically displayed on a scan tool or a code reader, and they provide valuable information about the nature of the problem and how to repair it.
Understanding the Code Format
The 12+ Van 84 codes are typically displayed in a specific format, which includes a combination of letters and numbers. The format is as follows: P0xxx, P1xxx, U0xxx, or C0xxx. The first letter or letters indicate the type of code, while the numbers provide more specific information about the problem. For example, a code that starts with “P” indicates a powertrain code, while a code that starts with “U” indicates a network communication code.
| Code Type | Description |
|---|---|
| P0xxx | Powertrain code |
| P1xxx | Manufacturer-specific powertrain code |
| U0xxx | Network communication code |
| C0xxx | Chassis code |
Common 12+ Van 84 Codes
There are many different 12+ Van 84 codes, and each one has a specific meaning. Some of the most common codes include:
P0123: Fuel Injector Circuit Malfunction. This code indicates a problem with the fuel injector circuit, which can cause issues with the engine's performance and fuel efficiency.
P0401: Exhaust Gas Recirculation Flow Insufficient. This code indicates a problem with the exhaust gas recirculation (EGR) system, which can cause issues with the engine's performance and emissions.
U0100: Lost Communication with Engine Control Module. This code indicates a problem with the communication between the engine control module (ECM) and other systems in the vehicle, which can cause issues with the engine's performance and safety.
