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.

COMPONENTS
ON-VEHICLE INSPECTION
1. INSPECT FRONT NO.2 SPEAKER
HINT:
Remove interior parts so that the front No.2 speaker can
be seen.
Check the speaker installation.
OK:
The speaker is securely installed.
If the result is not as specified, reinstall the front
No.2 speak ...
Speed sensor check (when using intelligent tester)
(a) Check the backward signal.
(1) Drive the vehicle in reverse for more than 1
second at 3 km/h (2 mph) or higher.
HINT:
Drive the vehicle in reverse and check the speed
sensor signal. Note that the signal check cannot
be completed if the vehicle speed is 45 km/h (28
mph) or more.
(b) Che ...
Precaution
1. REMOVAL AND INSTALLATION OF THE BATTERY TERMINAL
Before performing electrical work, disconnect the
battery negative (-) terminal in order to prevent a
short in the system.
When disconnecting and reconnecting the battery
cable, turn the ignition switch and lighting swit ...
