LDCRE Intake Manifold Pressure & Temperature Sensor for Cummins M11/ISC/ISL/ISM/ISX/ISB — Direct-Fit, OEM-Style

LDCRE intake manifold pressure and temperature sensor replaces part numbers 2897334, 4921324, 2872784 and RP32270001 for Cummins M11/ISC/ISL/ISM/ISX/ISB engines.

This engine sensor measures both manifold pressure and air temperature to provide the engine control system with accurate inputs. Built to match OEM fitment and electrical connections, the LDCRE unit is designed as a direct replacement for failing or worn original sensors on heavy-duty Cummins diesel engines. It’s constructed from corrosion-resistant materials and precision electronics to withstand under-hood heat, vibration, and contaminants common in commercial vehicles.

How does this sensor restore engine performance?

Replacing a faulty manifold pressure/temperature sensor helps the engine control module regain correct air-mass and boost measurements, improving fuel delivery and combustion timing. That can reduce rough idling, limp-home modes, and diagnostic trouble codes related to intake conditions.

• Restores accurate boost and intake air temperature readings to ECU/PCM
• Eliminates erratic sensor outputs that trigger fault codes
• Helps stabilize idle and transient throttle response
• Direct-fit electrical connector and mounting flange for easy swap

What vehicles and part numbers is this compatible with?

The LDCRE sensor is compatible with a range of Cummins diesel engines including M11, ISC, ISL, ISM, ISX and ISB series. It is intended as a replacement for multiple OEM part numbers, making it suitable for workshops and fleet maintenance.

• Replaces Cummins part numbers: 2897334, 4921324, 2872784, RP32270001
• Compatible engine families: M11 / ISC / ISL / ISM / ISX / ISB
• Designed to match original mounting and connector layout

How difficult is installation and what should I check before fitting?

Installation is straightforward for technicians familiar with intake sensors: typically one mounting fastener and a single electrical connector. Before fitting, compare the replacement to the removed sensor and check wiring, harness clips, and the mounting surface for damage.

• Simple direct-replacement design — one-to-one fit
• Verify connector pin count and orientation against old sensor
• Clean mounting surface and inspect harness for corrosion
• Torque mounting fastener to vehicle or engine maker specifications

What materials and durability features does this part offer?

LDCRE manufactures the sensor from robust materials to endure heavy-duty operating conditions. Seals and electronics are chosen to resist moisture, oil, and heat, extending service life compared with cheaper aftermarket units.

• Corrosion-resistant housing and mounting flange
• Sealed electronics and connector to protect against contaminants
• Engineered to meet or exceed common OEM performance benchmarks

Who this is for: fleet managers, professional diesel technicians, and owner-operators running Cummins M11, ISC, ISL, ISM, ISX or ISB engines who need a reliable, direct-fit intake manifold pressure and temperature sensor. Choose this LDCRE replacement when you want correct engine air-mass data restored quickly, lower diagnostic downtime, and a durable sensor that fits the original mounting and connector arrangement.
