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-409).
INSPECTION PROCEDURE
Refer to the EVAP System (See page ES-412).
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.
*2: If there is only a small amount of fuel in the fuel tank, stabilizing the EVAP pressure takes longer than usual.
The leak detection pump creates negative pressure through the reference orifice. When the system is normal, the EVAP pressure is in 724 to 752 mmHg* and saturated within a minute.
If not, the ECM interprets this as a malfunction. The ECM will illuminate the MIL and set DTC if this malfunction is detected in consecutive drive cycle.

HINT:
If any work is performed on the brake system or if air in the
brake lines is suspected, bleed the air out of the brake
system.
NOTICE:
Wash the brake fluid off immediately if it adheres to any
painted surfaces.
