Integrator.
Boost Duty Cycle (Duty Cycle %) Range: 0 to 100%
This parameter represents the duty cycle of the wastegate towards boost
pressure. A boost duty cycle of 100% means that the wastegate is
completely closed and all exhaust is routed through the turbocharger, at
the same time the wastegate duty cycle should be 0%.
Brake Depressed (Yes / No)
An indication that the brake pedal is pushed in.
Cam Count (Counts) Range: 0 to 255 Counts
This parameter represents a counter triggered by the camshaft sensor
signal.
Cam Pulse (Detected / Not Detected)
Whenever the cam position sensor is sensed by the ECM it will indicate a
value of DETECTED.
Catalytic Temp (°F) Range: 0° to 1832°
The catalytic converter temperature as calculated by the ECM.
CCP Duty Cycle (% of On Time) Range: 0 to 100%
The percentage of time that the vapor absorbing charcoal canister has
received an ON command.
CCP Purge (Yes / No)
An indication of whether the engine's vapor absorbing charcoal canister
has been signaled to purge its contents during normal engine operation.
See CCP Duty Cycle.
Check Engine Light (On / Off)
This reading corresponds to the CHECK ENGINE or SERVICE ENGINE
SOON light on the dashboard.
Clear Flood Mode (Yes / No)
An indication that the accelerator pedal is pressed to the floor with the
engine off to clear a flooded engine during a restart.
Clutch Depressed (Yes / No)
An indication by the ECM of whether the clutch is pushed in or not.
Coolant Temp (°F) Range: -40° to +389°
Coolant temperature. This reading should increase as the engine warms.
Cruise Control (On / Off)
The operating status of the cruise control system is available for engines
