If Cruise Control Adjusted Maximum Speed (SPN 7495) is supported, then SPN 7495 has priority over SPN 87. Maximum vehicle velocity at which cruise can be set. (SPN 7319) for the final speed used by the cruise control algorithm. For the parameter that includes the adjustment, see Cruise Control Speed If an algorithm that can modify the cruise control set point exists in the system, such as Predictive CruiseĬontrol or Adaptive Cruise Control, then Cruise Control Set Speed (SPN 86) will not include the speedĪdjustment made by that algorithm. See SPN 6809 for an alternate resolution. Value of set (chosen) velocity of velocity control system. Speed of the vehicle as calculated from wheel or tailshaft speed. Gage pressure of air in an engine starting system that utilizes compressed air to provide the force required Recommended that SPN 3609 be used as it has better resolution. Ratio of volume of liquid to total container volume of fluid reservoir in windshield wash system.Īftertreatment 1 Diesel Particulate Filter Intake Pressure (use SPN 3609)Įxhaust pressure as a result of particle accumulation on filter media placed in the exhaust stream. Indicated temperature of road surface over which vehicle is operating. Temperature of lubricant in steering axle. See SPN 6808 for an alternate resolution. Gage pressure of auxiliary water pump driven as a PTO device.
Relative position of the blower bypass valve. Operator’s park brake control, whether a pedal, lever or other control mechanism (see also SPN 619 and Switch signal which indicates when the parking brake is set. Switch signal which indicates the current axle range. Temperature of transmission #2 lubricant. The current position of the shift finger in the rail direction. The current position of the shift finger in the gear direction. The current modulated value for the air supply to the synchronizer brake. The current modulated value for the air supply to the synchronizer clutch. Temperature of liquid found in the intercooler located after the turbocharger.

0% represents no supply and 100% is full supply. The position of the valve used to regulate the supply of a fluid, usually air or fuel/air mixture, to anĮngine. The pneumatic pressure in the main reservoir, sometimes referred to as the wet tank.
NOTE – A value of 0 indicates continuous (real time) pressure readings. The interval at which the system will check the tire pressures (e.g., 5, 10, 15 min.). Level 2 is not used, Fuel Level 1 (SPN 96) represents the total fuel in all fuel storage containers. Ratio of volume of fuel to the total volume of fuel in the second or right-side storage container. The pressure of the air in the tank supplying the automatically shifting transmission. The current position of the splitter cylinder. NOTE-See SPNs 91 and 974 for additional accelerator position parameters. If a low idle validation switch is used in conjunction with accelerator pedal 2 position, use Accelerator SPN 91.In marine applications, this will typically be the operator’s second throttle lever. If an application has only one accelerator control, use The ratio of actual position of the second analog engine speed/torque request input device (such as anįor secondary accelerator control in an application.
In marine applications, this will typically be the operator’s third throttle lever.If a low idle validation switch is used in conjunction with accelerator pedal 3 position, use Accelerator This parameter is intendedįor the third accelerator control in an application. The ratio of actual position of the third analog engine speed/torque request input device (such as anĪccelerator pedal or throttle lever) to the maximum position of the input device. Means the valve is closed and no exhaust gas is flowing into the intake air stream. The position of the exhaust gas recirculation valve expressed as a percentage of full travel. (SPN 21 & SPN 1207 are not to be used – obsolete)Įngine Extended Crankcase Blow-by Pressureĭifferential crankcase blow-by pressure as measured through a tube with a venturi.Įngine Exhaust Gas Recirculation 1 Valve Position Temperature of the engine electronic control unit. See also SPN 109 for alternate range and resolution. Gage pressure of liquid found in engine cooling system. SeeĮngine Coolant Pressure 1 (Extended Range) Engine Fuel Filter Differential Pressure (see also SPN 1382)ĭifferential pressure measured across the fuel filter located between the fuel tank and the supply pump.
