What does a malfunction indicator light on OBD2 mean?
This light, in the OBD2 standard language, is also called a malfunction indicator light (MIL). When that light is on it means there is a certain sensor in the car that has sent an error message to the powertrain control module (PCM) which it can’t decode.
What are the OBD codes?
The On-Board scanner is a pair of systems with no exceptions. These systems are known to use codes referred to as On-Board diagnostic codes (OBD) which is a combination of Codes to get precise and brief you on the state of the car engine fault status.

How does the PCM work in an OBD 2?
The PCM calculates input signals from the crankshaft position sensor, camshaft position sensor, and throttle position sensor (among others depending upon the vehicle) to configure an ignition spark timing strategy. In a realistic sense, the camshaft position sensor and crankshaft position sensor are vital to operation of the OBD II ignition system.
