1. Understanding OBD2 Scanners and Torque

1.1. What is an OBD2 Scanner?

An OBD2 (On-Board Diagnostics II) scanner is a device used to access a vehicle’s computer system, allowing users to read diagnostic trouble codes (DTCs), monitor sensor data, and assess overall vehicle performance, according to the Environmental Protection Agency (EPA). These scanners connect to a standardized port found in most vehicles manufactured after 1996, providing valuable insights into the engine and other systems.

1.2. Why is Torque Important for Car Enthusiasts?

Torque, in automotive terms, is the rotational force an engine produces, dictating a vehicle’s ability to accelerate and perform tasks like climbing hills or towing loads. Car enthusiasts value torque because it directly relates to the driving experience, influencing how quickly a car responds to throttle inputs and how well it performs under various conditions.

1.3. How Does an OBD2 Scanner Measure Torque?

OBD2 scanners indirectly measure torque by monitoring related parameters such as engine speed (RPM), manifold absolute pressure (MAP), and throttle position. The scanner transmits this data to a connected device (like a smartphone or tablet) running specialized software, such as the Torque app, which then calculates the estimated torque output using complex algorithms, explains a study from the Society of Automotive Engineers (SAE).
