2GR-FE ENGINE CONTROL SYSTEM
– SFI SYSTEM
ES–263

DTC SUMMARY
HINT:
The 0.02 inch orifice is located inside the pump module.
DESCRIPTION
The circuit description can be found in the EVAP (Evaporative Emission) System (See page
ES-400
).
INSPECTION PROCEDURE
Refer to the EVAP System (See page
ES-400
).
MONITOR DESCRIPTION
5 hours
*1
after the ignition switch is turned off, the electric vacuum pump creates negative pressure
(vacuum) in the EVAP (Evaporative Emission) system. The ECM monitors for leaks and actuator
malfunctions based on the EVAP pressure.
HINT:
*1
: If the engine coolant temperature is not below 35
°
C (95
°
F) 5 hours after the ignition switch is turned off,
the monitor check starts 2 hours later. If it is still not below 35
°
C (95
°
F) 7 hours after the ignition switch is
turned off, the monitor check starts 2.5 hours later.
