Distance traveled since diagnostic trouble codes cleared `CLR_DIST`SAE J1979Confirmed

Distance accumulated since DTCs were cleared (via an external test equipment or possibly, a battery disconnect). This parameter is not associated with any particular DTC. It is simply an indication for inspection/maintenance, of the last time an external test equipment was used to clear DTCs. If greater than 65,535 km have occurred, will remain at 65,535 km and not wrap to zero.

Pelican can show this parameter as the distance since trouble codes were cleared.

Number of OBD warm-up cycles since all DTCs were cleared (via an external test equipment or possibly, a battery disconnect). A warm-up is defined in the OBD regulations to be sufficient vehicle operation such that coolant temperature rises by at least 22°C (40°F) from engine starting and reaches a minimum temperature of 70°C (160°F) (60°C (140°F) for diesels). This PID is not associated with any particular DTC. It is simply an indication for inspection/maintenance, of the last time an external test equipment was used to clear DTCs. If greater than 255 warm-ups have occurred, this parameter will remain at 255 and not wrap to zero.

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.

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.

Commanded equivalence ratio `EQ_RAT`SAE J1979Confirmed

Commanded fuel/air equivalence ratio (lambda): actual A/F ratio over stoichiometric A/F ratio, so above 1 is lean and below 1 is rich. Multiply by the fuel's stoichiometric A/F ratio for the commanded A/F ratio (gasoline: 14.64 x 0.95 = 13.9). Systems with conventional oxygen sensors show the commanded value in open loop and 1.000 in closed loop; systems with wide-range (linear) sensors show it in both. On engines whose banks are controlled independently, this is bank 1.

Pelican can show this parameter as the commanded lambda.
