Intake Manifold Pressure Temperature Sensor LDCRE 14935-JF00A Metal

Description

Product Overview

The LDCRE intake manifold pressure temperature sensor is a precision‑engineered component designed specifically for a range of Cummins engine families, including the M11, ISC, ISL, ISM and ISX series. Constructed from a robust combination of metal, ceramic and high‑temperature polymer, the sensor delivers reliable performance in demanding environments such as heavy‑duty trucks, construction equipment, and industrial generators. Its digital output provides clear, real‑time data that can be integrated with modern engine control units, allowing operators to monitor both manifold pressure and temperature simultaneously. With an upper temperature rating of 392 °F, the sensor maintains accuracy even under extreme thermal stress, ensuring that critical engine parameters remain within safe operating limits. The compact dimensions of 2.76 × 1.65 × 1.65 inches and a lightweight design of just 0.634 ounces make installation straightforward without compromising durability. The sensor’s part number 14935-JF00A aligns with OEM specifications, ensuring a seamless replacement for original components such as 2897334, 4921324, 2872784 and RP32270001. Its direct‑replace mounting type eliminates the need for custom brackets or extensive wiring modifications, reducing service time and labor costs for fleet maintenance teams.
Compatibility is a cornerstone of the LDCRE sensor’s design philosophy. By matching the exact dimensions and electrical characteristics of the original Cummins part, the sensor fits seamlessly into the intake manifold cavity, preserving the integrity of the engine’s airflow path. The built‑in ceramic element provides stable temperature sensing across the full operating range, while the metal housing protects against vibration, corrosion, and exposure to oil or coolant. Installation requires only the removal of the faulty unit, alignment of the mounting tabs, and a secure torque to the manufacturer‑specified value. No additional adapters or sealants are necessary, which minimizes the risk of leaks and ensures a tight seal that maintains the engine’s calibrated pressure dynamics. The sensor’s digital signal is compatible with standard OBD‑II diagnostic tools, allowing technicians to quickly verify functionality and calibrate the system after replacement.
Performance benefits extend beyond simple measurement accuracy. By delivering precise pressure data, the sensor enables the engine control module to optimize fuel injection timing, improving combustion efficiency and reducing emissions. Simultaneously, accurate temperature feedback helps prevent overheating of the intake manifold, protecting downstream components such as turbochargers and intercoolers. Operators can expect smoother engine response during acceleration, better fuel economy under steady‑state cruising, and enhanced durability of critical engine parts. The sensor’s rapid response time ensures that transient pressure spikes are captured in real time, providing the control system with the information needed to adjust boost pressure on the fly. This level of control is especially valuable in applications where load conditions fluctuate frequently, such as in construction equipment that alternates between idle, low‑load, and high‑load cycles throughout a workday.
Each sensor undergoes rigorous testing to meet industry standards. LDCRE subjects every unit to thermal cycling, vibration endurance, and electromagnetic compatibility assessments, ensuring reliable operation from sub‑freezing temperatures to the maximum 392 °F rating. Certified to ISO 9001 quality management protocols, the sensor’s production line maintains traceability and consistency, giving customers confidence in long‑term performance. Independent third‑party labs verify the sensor’s accuracy and durability, providing documented proof of compliance with automotive safety regulations.
Beyond performance, the sensor contributes to environmental sustainability. Its metal housing is fully recyclable, and the ceramic core is designed for a long service life, reducing the frequency of replacements and associated waste. By enabling more efficient combustion, the sensor helps lower fuel consumption and emissions, supporting greener operation of diesel engines in fleets that prioritize eco‑friendly practices.

Usage

The LDCRE sensor is ideally suited for heavy‑duty trucks that operate in harsh climates, where temperature extremes and dust exposure can challenge less robust components. Fleet managers in logistics, mining, and oil‑field services will find the sensor’s durability and low maintenance requirements valuable for keeping vehicles on the road longer. In addition to on‑road applications, the sensor performs reliably in off‑road equipment such as excavators, bulldozers, and agricultural tractors, where intake manifold pressure monitoring helps maintain optimal engine performance under variable load conditions.
Technicians installing the sensor benefit from its direct‑replace design, which shortens service intervals and reduces downtime. Because the sensor integrates with existing engine control software, no additional programming is required after installation; the system automatically recognizes the new component and resumes normal operation. This ease of use makes the LDCRE sensor a practical choice for both in‑house service bays and mobile repair units that need to perform quick swaps on the roadside. The sensor’s compatibility with standard diagnostic scanners also simplifies troubleshooting, allowing quick verification of pressure and temperature readings during routine maintenance checks.
Cold‑weather starts and high‑altitude operations place additional demands on engine monitoring. The sensor’s rapid response and accurate temperature sensing ensure that the engine control unit can adjust fuel delivery and boost pressure to compensate for thinner air or colder intake temperatures. This capability reduces the risk of hard starts, improves warm‑up times, and maintains power output in mountainous regions, making the sensor a valuable upgrade for vehicles that travel across diverse terrains.
