Vacuum (in-Hg) Range: 0 to 60 in-Hg
The PCM calculated vacuum reading as converted from barometric
pressure and manifold absolute pressure.
Vehicle Speed (MPH)
The PCM reads input from the speed sensor to determine if the vehicle is
changing speed or idling with the throttle closed.
Wastegate Cycle (% on time) Range: 0 to 100%
For turbocharged vehicles the wastegate is used to keep exhaust gases from
affecting the impeller of the turbine and pass out through the exhaust. The
wastegate solenoid will cycle once desired manifold absolute pressure has
been obtained to prevent overboost. This parameter is displayed as a per-
centage that the wastegate is open (on-time).
Water-in-Fuel (Volts) Range: 0 to 5 Volts
This parameter indicates water present in the fuel system. Higher water con-
tent will equate to a higher voltage.
