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.

You'll Need Notepad and Pencil for this job
Put your transmission in park (automatic) or neutral (manual).
Launch the engine and then race it up to 2500 rpm. Gradually, bring the engine speed down to idle again.
Power on the air conditioner for about a moment---if your Stratus model is so-equipped---and then turn it off.
Depress the brake pedal if you have an automatic transmission, and move the shift selector through every gear and than back to park.
Power off the engine and grab a small notepad and pencil.
Turn the ignition key to the on position and then to the off position. Repeat this step once more and then turn the ignition key to the on position again and let it stay there. You have now accessed your Stratus's computer trouble code memory.
Wait for the OBD Check Engine light on the dashboard to start flashing.
Count the number of times the Check Engine light flashes before pausing and record the number, which will be a single-digit number.
Count the number of flashes in the second sequence, following the first pause. Place this single-digit number next to the first. For example, if the light flashes four times, pauses, and then flashes three more times, this will be recorded as 43.
Wait for a longer pause after the first two sequences of flashes and record the next two digits in the same manner as in the previous step. Each two-digit number is an error code stored in the computer memory. When the computer reaches the end of the trouble codes stored in memory, it will repeat the same codes so you may check your notes. At the end of the second cycle of sequences, turn the key to the off position.
Consult the error code definitions obtained from the computer memory in the user manual for your specific Stratus model. There are a lot of online stores over the internet; you can find that what you need online.
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.
Instruction of Reading a Car OBD Computer
As we know, all cars sold In USA after 1996 should be OBD 2-compliant. OBD stands for On-Board Diagnostic; these cars all have a data link connector supplying a way to access the on-board diagnostic computer system.
