The vehicle onboard computer is an electronic system that displays both instantaneous parameters (current time, vehicle speed, engine speed, engine temperature, interior and exterior temperatures, remaining fuel in the tank, onboard voltage, etc.) and diagnoses malfunctions of vehicle systems.
An onboard computer, also known as an OBD or on-board diagnostic computer, is a small computer that is built into modern cars. Its purpose is to monitor the performance of the engine and other systems, and to provide diagnostic information if something goes wrong.
The onboard computer keeps track of various things such as engine temperature, oil pressure, speed, and throttle position. It also stores codes that can be read by a mechanic to diagnose problems. Some onboard computers also have the ability to display information on a dashboard screen.
The onboard computer is an important part of a car’s overall health monitoring system. By keeping track of how the car is performing, it can help prevent small problems from becoming big ones. It can also save you time and money by diagnosing problems quickly and keeping track of things like engine temperature and oil pressure, it can help you avoid costly repairs.
While the onboard computer is a very useful tool, it is important to remember that it is not a substitute for regular maintenance. Be sure to have your car checked by a qualified mechanic on a regular basis to ensure that everything is in good working order.

Frequently Asked Questions (FAQ)
When did cars start having onboard computers?
The first automotive onboard computer was the 1980 Pontiac Turbo, which had an electronic computer module controlling engine functions. This model is widely recognized as being the first to introduce many of the features that are now commonplace in modern cars, such as fuel injection and electronic monitoring of engine performance. Since then, cars have seen a rapid evolution in terms of technological advancements, with computers becoming increasingly advanced and connected. Nowadays, most vehicles come equipped with on-board computers that are capable of performing complex tasks such as navigation assistance and diagnostics. These systems help drivers stay safe on the road and maximize their vehicle’s performance by optimizing fuel efficiency and handling capabilities.
Is there a computer in every car?
No, not every car is equipped with a computer. Some cars are built with a computerized system that can be used for entertainment and navigation systems, but not all cars come with this feature. Most cars still only have analog components such as an internal combustion engine and manual transmission. However, modern vehicles are increasingly relying on computers to provide many of the features we expect in today’s automobiles including adaptive cruise control, lane assist, and other driver assistance systems.
Where are computers located in cars?
Modern cars now come with a range of sophisticated computer systems that can be found in many locations. These computers are typically located in the engine, transmission, infotainment system, and other mechanical components of the vehicle. The engine contains several sensors and computer chips to control the fuel injection system and ignition timing, as well as the air-fuel mixture. The transmission also has multiple electronic controls for engaging gears and managing torque output.
