ENGINE GENERAL INFORMATION AND DIAGNOSIS (G16/J20 ENGINES) 6-31
CANIST PRG DUTY (EVAP CANISTER PURGE FLOW DUTY, %)
This parameter indicates valve ON (valve open) time rate within a certain set cycle of EVAP canister purge valve
which controls the amount of EVAP purge.
FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in the fuel tank.
FUEL PUMP (ON/OFF)
ON is displayed when the ECM (or PCM) activates the fuel pump via the fuel pump relay switch.
FUEL CUT (ON/OFF)
ON : Fuel being cut (output signal to injector is stopped).
OFF : Fuel not being cut.
EGR VALVE (%)
This parameter indicates opening rate of EGR valve which controls the amount of EGR flow.
PSP SWITCH (ON/OFF)
ON : PSP switch detects P/S operation (high PS pressure).
OFF : PSP switch not detects P/S operation.
A/C SWITCH (ON/OFF)
ON : Command for A/C operation being output from A/C amplifier/HVAC control module.
OFF : Command for operation not being output.
PNP SIGNAL (TRANSMISSION RANGE SWITCH, P/N or D range)
Whether the transmission range switch (P/N position switch) at P or N range or at R, D, 2 or L range is displayed.
If at P or N range, “P/N range” is displayed and if at R, D, 2 or L range, “D range” is displayed.
A/C CONDENSER FAN (ON/OFF)
This parameter indicates the state of the A/C Condenser Fan control signal.
ELECTRIC LOAD (ON/OFF)
ON : Headlight, clearance light or rear window defogger ON signal inputted.
OFF : Above electric loads all turned OFF.
BRAKE SW (ON/OFF)
This parameter indicates the state of the brake switch.
BLOWER FAN (ON/OFF)
This parameter indicates the state of the blower fan motor switch.
VSS (4-A/T) (km/h, MPH)
It is computed by using pulse signals from vehicle (output) speed sensor on 4-speed automatic transmission.
