System Monitors OBD II diagnostic systems perform many dedicated emissions systems monitor tests. Some of these monitors run continuously, which means they are always operating whenever the vehicle is running. These continuous monitors include: misfire detection, fuel trim, and comprehensive component monitors.

.

Considering this, what are the conditions for running the DTC?

The engine speed is greater than 500 RPM. The exhaust gas recirculation (EGR) valve is OFF. This DTC runs continuously within the enabling conditions. The ECM detects that the MAF sensor air flow ratio is not within a predetermined range of the calculated MAF air flow ratio for greater than 16 seconds.

Subsequently, question is, what is MIL status off? The Malfunction Indicator Lamp (MIL) or CHECK ENGINE light as it is more commonly called, is essentially an emission warning light. If the light comes on, it means the Onboard Diagnostics II system (OBD II) has detected an emissions-related problem.
