Product Description
MOPAR 68447684AB INTAKE AIR TEMPERATURE (IAT) SENSOR FOR 07.5-24 RAM 2500/3500 WITH 6.7L CUMMINS ENGINE
Restore accurate air intake monitoring and maintain peak diesel performance with the genuine Mopar 68447684AB Intake Air Temperature (IAT) Sensor for 2007.5-2024 Ram 2500 and 3500 trucks equipped with the legendary 6.7L Cummins turbo diesel engine. This OEM Mopar sensor precisely measures incoming air temperature, allowing the engine control module to optimize fuel delivery, turbocharger operation, combustion efficiency, and emissions performance.
The Mopar 68447684AB IAT sensor plays a critical role in maintaining proper air-to-fuel ratios under varying driving conditions including towing, hauling, performance driving, and cold-weather operation. A faulty or failing intake air temperature sensor can contribute to hard starts, rough idle, reduced fuel economy, poor throttle response, excessive smoke, and diagnostic trouble codes.
Manufactured to strict OEM Mopar standards, this direct-fit replacement sensor provides factory-level accuracy, reliability, and long-term durability in harsh diesel operating environments. Unlike low-quality aftermarket sensors, genuine Mopar components deliver proper calibration and seamless integration with your Ram’s engine management system.
This sensor is commonly referenced as a T-MAP sensor or charge air temperature sensor and is designed for use on select 6.7L Cummins applications spanning multiple Ram HD generations.
FAQ
What does the intake air temperature sensor do?
The IAT sensor monitors the temperature of incoming air entering the engine so the ECM can properly adjust fuel delivery, timing, and turbocharger operation.
What are symptoms of a failing IAT sensor?
Common symptoms include hard starting, rough idle, reduced fuel economy, poor throttle response, increased smoke output, limp mode, and check engine lights.
Is this a genuine Mopar OEM sensor?
Yes. The 68447684AB is a genuine OEM Mopar sensor designed specifically for Ram trucks with the 6.7L Cummins engine.
Is this the same as a MAP or T-MAP sensor?
This sensor is commonly referenced as a charge air pressure and temperature sensor (T-MAP sensor) depending on vehicle configuration.
Does this install directly into the intake system?
Yes. This sensor is designed as a direct OEM replacement using factory mounting and electrical connections.
