ED (SMALL LEAK)
1. OUTLINE OF DIAGNOSIS
Check if there is a leakage in fuel system or not, and perform the function diagnosis of valve.
In this system diagnosis, check for leakage and valve function is conducted by changing the fuel tank pres-
sure and monitoring the pressure change using the fuel tank pressure sensor.
When in 0.04 inch diagnosis, perform in the order of mode Z → mode A → mode B → mode C and mode D;
When in 0.02 inch diagnosis, perform in the order of mode A → mode B → mode C → mode D and mode E.

GENERAL DESCRIPTION
3. GENERAL DRIVING CYCLE
0.04-inch Diagnosis
Perform the diagnosis only once in 851 seconds or more after starting the engine, at a constant speed of 32
km/h (20 MPH) or more.
Pay attention to the fuel temperature and fuel level.
0.02-inch Diagnosis
Perform the diagnosis after 120 seconds or more after starting the engine, at a constant engine RPM of 30
km/h (19 MPH) or higher, to judge as NG or OK.
If OK/NG judgment is not possible, repeat the diagnosis.
Pay attention to the fuel temperature and fuel level.
4. DIAGNOSTIC METHOD
0.04-inch Diagnosis
Mode Z: (Purge control solenoid valve opening failure diagnosis)
When performing the leakage diagnosis of the EVAP system, the purge control solenoid valve must operate
properly. Therefore, mode Z is used to diagnose a stuck open condition of the purge control solenoid valve
by monitoring the tank pressure.
Note that if a purge control solenoid valve stuck open fault is detected, the EVAP system leakage diagnosis
is cancelled.
