You need an OBD scanner to explain what happen with the car when the check light comes on. There are kinds of OBD scanners for use and which kind of OBD tool to buy relies on the model and year of your car it will be used on and the type of diagnostic functions which you needed. OBD scanners can show us why a check engine light comes on.
When the car check engine light comes on, you need an OBD scanner to explain what happen with the car. There are kinds of OBD scanners for use and which kind of OBD tool to buy relies on the model and year of your car it will be used on and the type of diagnostic functions which you needed. OBD scanners can show us why a check engine light comes on.
OBD History
The Unites States Environmental Protection Agency (EPA) required OBD to become standardized in 1996. Cars 1995 and earlier use diagnostic systems unique to their manufacturer. For instance, diagnostic procedures for a 1990 Ford car and a 1990 Chevy Blazer car are not the same. Cars after 1996 use the same process and system of codes.
OBD Scanner
Cars predating 1996 can be placed into self-testing mode. Trouble codes are conveyed by a flashing check engine light. There are scanners available for these cars, but each car needs its own special scanner. The question here is whether or not it is worth buying a scanner at all, because of their limited use and functionality.
OBD2 Scanner
Most OBD2 scanners are not reverse compatible. They cannot read code from cars predating 1996. But they can be widely used on makes and car models after 1996. When comparing scanners, a potential buyer needs to assess how much they will use it. Scanners can be simple code readers, good for only retrieving active codes from the OBD2 system. Much dearer scanners record and display live data from a car's array of sensors.
Multi-Functioning Devices
As technology becomes more advanced and sophisticated, OBD scanners become more complicated. Some OBD 2 scanners can be programmed to interact with other diagnostic systems, like anti-lock braking systems brakes. There are also other devices called micro-tuners. Not only can these read code and monitor sensor data, but they can be used to reprogram your car's power train control module.
Comparison Shopping
Make a list of everything you needed and think about the questions as below: Dose it be needed to monitor sensors in cars? How many cars will it be used on? Does it still have some other functions?

Tips to Check the Engine OBD Code without a Code Reader on a Dodge Stratus
Car manufacturers in USA started to equip their cars with the OBD system in the early 1980s. In 1996, when the system was made mandatory, most manufacturers changed to the second generation system, the OBD 2. Trouble codes stored in the computer of the first generation OBD system may be accessed through different methods, relying on the special make and model.
Instruction of Replacing a Neon MAP Sensor with OBD 2 scanner
Manifold absolute pressure (which short for MAP) sensor of car is located on the front portion of the Neon's air intake manifold and has two small screws securing it into place. MAP sensors are responsible for identifying the air pressure within the manifold and sending a reading to the engine's ECU (engine control unit) referring to the voltage level for the spark in the ignition cylinder.
Instruction Retrieving Car Trouble Codes without OBD tool
Manufactured before 1995 model of car typically come with the OBD 1 trouble-code system; cars made after 1995 generally come with the OBD 2 system. The differences between the two systems are that the older codes system contains only two digits, while the new codes system start with a letter showing what system in the engine is fault, followed by a series of numbers.
