Bits 368 to 383 of the reply, 16 bits.

Formula: $val$
Range: 0 to 65535 s
Unit: s

Confirmed for 2006 to 2007. In testing for 1999 to 2005, 2008 to 2009.

DTCs

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.

Range: 0 to 29.4
Unit: Number

Calculated engine load `LOAD_PCT`SAE 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.

Pelican can show this parameter as the engine load.

Bits 0 to 7 of the reply, 8 bits.

Formula: $\frac{val \times 100}{255}$
Range: 0 to 100 %
Unit: %

Confirmed for 2006 to 2007.

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.

Engine coolant temperature `ECT`SAE J1979Confirmed

Your engine temperature must operate within a certain temperature range to operate efficiently and safely. If it runs too hot, then your engine could be permanently damaged. If it runs too cold, then your engine will use more fuel than necessary.

Pelican can show this parameter as the engine coolant temperature.
