International Harvester Throttle Position Sensor: A Comprehensive Guide

What is the International Harvester Throttle Position Sensor?

The International Harvester Throttle Position Sensor (TPS) is a crucial component in diesel engines, particularly those used in heavy-duty trucks and tractors. This sensor is responsible for monitoring the position of the throttle valve, which controls the amount of air entering the engine. By accurately measuring the throttle position, the TPS helps maintain optimal engine performance, fuel efficiency, and emissions control.

Key Components and Specifications

The International Harvester Throttle Position Sensor comes in various models and configurations, including the 2507256C91, 2586248C9, and 133284. These sensors feature different electrical connections, mounting styles, and temperature ranges, making them suitable for a wide range of applications.

Applications and Compatibility

The International Harvester Throttle Position Sensor is compatible with several diesel engines, including the 6.8DT, 14.6DT, and 7.6DT models, produced between 1971 and 1992. It is commonly used in International Harvester trucks and tractors, as well as other heavy-duty vehicles that require precise throttle control.

Importance in Engine Performance

A properly functioning International Harvester Throttle Position Sensor plays a vital role in maintaining optimal engine performance. It ensures accurate fuel delivery, helps prevent engine stalling, and reduces emissions by providing real-time data to the engine control unit (ECU).

Choosing the Right Throttle Position Sensor

When selecting an International Harvester Throttle Position Sensor, consider the specific requirements of your vehicle and engine. It is essential to choose a sensor that is compatible with your vehicle's make, model, and year, as well as its specific engine type.
