CC:DTC P0442 EVAPORATIVE EMISSION CONTROL SYSTEM LEAK DETECT-
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
0.04-inch Diagnosis
Mode Mode Description Diagnosis Period
Mode Z
(Purge control solenoid valve open-
ing failure diagnosis)
Diagnosis starts when there is a change in fuel tank pressure
amount. Purge control solenoid valve open trouble diagnosis
begins.
3 — 16 seconds
Mode A
(Estimated evaporation amount)Calculate the tank pressure change amount (P1). 10 seconds
Mode B
(Sealed negative pressure, large
leakage judgment)
Introduce the intake manifold pressure to the fuel tank and reduce
the tank pressure to the desired value. If the tank pressure cannot
be reduced, it is diagnosed as large leak.
5 — 25 seconds
Mode C
(Pressure increase check,
advanced OK judgment)
Wait until the tank pressure retur ns to the targeted pressure (star t
level of P2 calculation). If the tank pressure does not become the
value, make advanced OK judgment.
1 — 15 seconds
Mode D
(Negative pressure variation mea-
surement, evaporation leakage
diagnosis)
Calculate the tank pressure variation (P2) and obtain the diagnos-
tic value using P1 found in Mode A.
