RIDEX Fuel Pressure Sensor – Overview

The RIDEX 3942S0015 fuel pressure sensor is engineered to deliver precise and reliable measurement of fuel system pressure for a wide range of light‑to‑medium duty vehicles. Designed with high durability in mind, it meets OEM specifications for Fiat, Ford, Peugeot, Citroën, Mitsubishi, and related models.

Key Identification Numbers

• Part Number: 3942S0015
• OEM Reference: 8C1Q9D280AA1465A034
• Serial Range: 966461388096654006801497163

Core Functionality

The sensor converts the mechanical pressure of fuel in the high‑pressure rail into an electrical signal. This signal is then interpreted by the engine control unit (ECU) to adjust fuel delivery, ensuring optimal combustion efficiency and emissions compliance.

Electrical Characteristics

• Signal Type: Analog voltage output (0–5 V)
• Operating Voltage: 12 V DC ±10%
• Output Range: 0.2 V to 4.8 V corresponding to 0–100 psi
• Signal Accuracy: ±1% of full scale
• Temperature Range: –40 °C to +125 °C

Mechanical Design

• Housing Material: High‑strength alloy with corrosion resistance coating
• Mounting Interface: Standard threaded connection (M6 × 1.0 mm)
• Seal Type: O‑ring compatible with fuel system standards
• Dimensions: Length 70 mm, Diameter 15 mm

Vehicle Compatibility

The sensor is specifically calibrated for the following vehicle families:

• Ford Transit Mk6 (including Transit Tourneo and Transit FB variants)
• Fiat Ducato, Fiat 500L, and related commercial models
• Peugeot Boxer, Peugeot 3008, and other light commercial vehicles
• Citroën Jumper, Citroën C3, and similar platforms
• Mitsubishi L200/Triton, Mitsubishi Outlander, and related models

Installation Notes

1. Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove the existing fuel pressure sensor by unscrewing the mounting bolt.
3. Clean the mating surface on the fuel rail with a solvent compatible with fuel systems.
4. Insert the new RIDEX sensor, ensuring proper alignment of the O‑ring.
5. Tighten the mounting bolt to the manufacturer’s torque specification (typically 15 Nm).
6. Reconnect the battery and perform a diagnostic scan to verify correct sensor operation.

Performance Highlights

• High Accuracy: Maintains ±1% accuracy across the full pressure range, enabling precise fuel metering.
• Fast Response Time: Less than 50 ms to reach steady‑state after a pressure change, critical for rapid engine load adjustments.
• Robust Construction: Designed to withstand harsh operating environments, including high vibration and temperature extremes.
• Long Service Life: Expected lifespan of over 200,000 km under normal driving conditions.

Diagnostic Compatibility

The sensor’s analog output is fully compatible with standard OBD‑II diagnostic tools. When connected to a scan tool, the ECU will display real‑time fuel pressure values, allowing technicians to confirm proper sensor function or identify potential issues such as leaks or pump failure.

Quality Assurance

Each RIDEX 3942S0015 unit undergoes rigorous testing:

• Pressure calibration against traceable reference gauges.
• Electrical noise immunity assessment in automotive electromagnetic environments.
• Environmental stress screening (temperature cycling, vibration, and humidity).
