CheckEngineLightOn
Malfunction indicator lamp MILSAE J1979Confirmed
The MIL status is OFF during key-on, engine-off bulb check unless MIL has also been commanded ON for a detected malfunction. The status reflects whether there are confirmed DTC(s) stored that are illuminating the MIL. It should not reflect the status of the MIL, which could be on for a function check, flashing I/M readiness or flashing for misfire.

Engine load
Calculated engine load LOAD_PCTSAE J1979Confirmed
Represents the amount of work the engine is doing. Expected to reach 100% at wide open throttle/wide open pedal at any altitude, temperature or rpm for both naturally aspirated and boosted engines. If engine load is limited for powertrain protection e.g. engine/turbocharger protection, this value may not reach 100%. For hybrid vehicles, indicates the torque produced only by the internal combustion engine, not the torque being delivered by the entire powertrain. For electric vehicles, the meaning of this parameter is undefined.
