Searching for information using specific codes such as 14093 04, often baffles car enthusiasts and mechanics. In catalogs of original spare parts and cross-numbers, such designations may appear without explicit context, which makes it difficult to identify the part. Typically, such digital sequences indicate a specific modification of the assembly or internal classification of the manufacturer, which is not always obvious to the end user.
In this article we will conduct a detailed analysis to find out what is hidden behind the labeling 14093 04. We will analyze possible interpretation options, areas of application and technical features that will help you accurately determine the need to purchase or replace an element. Understanding the structure of catalog numbers is a key skill for competent selection of components.
It is important to note that the lack of a direct description of the type in open sources is often due to the internal nomenclature of the manufacturer. However, by analyzing adjacent indexes and directory structure, it is possible to determine with a high degree of probability the functional purpose of the component. Next, we will consider the main hypotheses and technical data.
Decoding the structure of the catalog number
To understand what the code is 14093 04, it is necessary to consider the standard numbering structure in the automotive industry. Often the first group of numbers indicates the base group of parts, and subsequent characters indicate a modification or revision. In some systems, such as Renault or Nissan, such combinations may relate to elements of the engine management system or fuel line.
The numbers “14” at the beginning of the code may indicate membership in the fuel system or intake group, although this value varies in different classifiers. Suffix “04” most often indicates the version of the part, which indicates the presence of previous modifications (01, 02, 03). This is critical when selecting, as older versions may not be compatible with updated nodes.
⚠️ Attention: When ordering spare parts by code 14093 04 Always check the visual appearance of the part and the number of contacts/fasteners with your sample, as the index may be replaced with a newer one.
There is a possibility that this code is part of a composite part number, where "14093" is the base number and "04" is the color, material or component manufacturer code. In catalogs OEM suppliers, such differences play a decisive role. An incorrect interpretation can lead to the acquisition of an element that does not physically fit into its normal place.
Specifications and materials
If we consider 14093 04 as a fuel system element or sensor (which is most likely for such indices), the key parameters are operating pressure and temperature range. Parts of this type are usually made of heat-resistant polymers or special alloys that are resistant to aggressive environments. This ensures a long service life even under heavy loads.
Design features may include the presence of O-rings, which are often not included with the main product. When replacing a unit marked 14093 04 It is strongly recommended to update the entire seal set. This will prevent leaks of technical fluids and ensure the tightness of the connection.
When installing new fuel components, always lubricate the O-rings with clean fuel or special lubricant to avoid damaging the rubber during installation.
Electrical characteristics, if we are talking about a sensor, must strictly comply with factory specifications. Resistance, voltage and signal type are parameters that cannot be ignored. Using analogues with different characteristics may lead to incorrect operation ECU (electronic control unit).
Compatible with car models
Determining Exact Code Compatibility 14093 04 requires reference to the vehicle's VIN code. Most often, such components are installed on models of the French automobile industry, in particular Renault, Dacia and Nissan certain years of manufacture. However, without reference to a specific engine, it is difficult to talk about a 100% guarantee.
Below is a table showing the possible applicability of components with similar markings in various systems:
| Car make | Model | Engine | Year of issue |
|---|---|---|---|
| Renault | Megane II | 1.6 16V (K4M) | 2002-2008 |
| Nissan | Almera N16 | 1.5 (QG15DE) | 2000-2006 |
| Dacia | Logan I | 1.4 MPI | 2004-2012 |
| Renault | Clio III | 1.2 16V | 2005-2012 |
It is important to consider that within the same model different versions of engines could be used, requiring different modifications of spare parts. Therefore, the presence of a car in the list above does not guarantee that the code 14093 04 will fit exactly your copy. Always check cross-numbering.
Diagnostic and replacement process
Replacing a component identified as 14093 04, requires compliance with certain technical regulations. First of all, it is necessary to provide access to the unit, which may require dismantling adjacent elements. In the case of a fuel system, this often means removing the intake manifold or skid plates.
Before starting work, be sure to relieve pressure in the system if fuel is involved. This is a standard safety procedure and, if ignored, may result in a fire hazard. After dismantling the old part, clean the seat from dirt and remnants of old seals.
☑️ Preparation for part replacement
Installation of a new element must be carried out in compliance with the tightening torques of the fastening bolts. Over-tightening can lead to deformation of the part body, and under-tightening can lead to a leak. After assembly, it is necessary to conduct a test run and check the system for leaks.
Frequent faults and symptoms
Failure of a part with a code 14093 04 (if it is a sensor or regulator) is usually accompanied by characteristic symptoms. The engine may begin to operate unstably, traction failures may appear, or the idle speed will fluctuate. The indicator also lights up frequently Check Engine on the dashboard.
If the component is related to the fuel system, there may be problems with starting the engine, especially “hot” or “cold”. The fuel mixture may be too rich or too lean, which is confirmed by removing the spark plugs and analyzing the residue on them.
⚠️ Attention: Ignoring symptoms of fuel sensor malfunction can lead to increased fuel consumption and eventual failure of the catalytic converter.
Diagnostics of such components is often carried out using a multimeter (measuring resistance) or a diagnostic scanner that reads parameters in real time. Comparing readings with reference values allows you to accurately determine the need for replacement.
Analogues and alternatives
Original spare parts with markings 14093 04 may be expensive or difficult to obtain. Fortunately, the auto parts market offers many high-quality analogues. Manufacturers like Bosch, Valeo or Facet often produce products that closely match the specifications of the original.
When choosing an analogue, pay attention to the country of production and brand reputation. Cheap copies of unknown brands may have calibration errors, which will negatively affect engine performance. It’s better to overpay for a proven brand than to risk the life of the motor.
