Diagnostic Trouble Code (DTC) Detecting Criteria
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.

DTC
P0457 Evaporative Emission Control System Leak Detected (Fuel Cap Loose/Off)
Purge control solenoid valve functional diagnosis is performed by monitoring the tank pressure in mode Z.
Normality Judgment
Make OK judgment 3 seconds after Mode Z starts, and change to Mode A if OK.

Judge normal when these calculations are completed.
Abnormality Judgment
If OK judgment cannot be made, extend Mode Z 16 seconds more, and Judge as NG when all the criteria be-
low are completed in 16 seconds.

GENERAL DESCRIPTION
Leak Diagnosis
DTC
P0442 Evaporative Emission Control System Leak Detected (Small Leak)
P0457 Evaporative Emission Control System Leak Detected (Fuel Cap Loose/Off)
Diagnostic method
The diagnostic method consists of creating a sealed vacuum in the fuel tank and then determining the pres-
ence of leakage from the speed at which the tank internal pressure returns to atmospheric pressure.
Mode A: (Estimated evaporation gas amount)
Calculate the tank pressure change amount (P1) when using mode A. After calculating P1, switch to mode B.
Mode B: (Negative pressure sealed)
Introduce negative pressure in the intake manifold to the tank.
Approx. 0 → –1.4 (0 → –10.5, 0 → –0.41) kPa (mmHg, inHg)
When the pressure above (desired negative pressure) is reached, enters Mode C.
In this case, if the tank pressure does not become the desired negative pressure, judge that there is a large
leakage (10 seconds or 25 seconds) in the system.
Abnormality Judgment
Judge as NG (large leak) when the criteria below are met.
Mode C: (Check pressure rise)
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 cal-
culation.)
Change to Mode D when the tank pressure returns to the start level of P2 calculation.
Judge immediate OK and change to Mode E when it does not return in spite of spending the specified time.
Mode D: (Measure amount of negative pressure change)
Monitor the tank pressure change amount when using mode D. In this case, the tank pressure increases,
(nears atmospheric pressure) because evaporation occurs. However, if any leakage exists, the pressure in-
creases additionally in proportion to this leakage. The pressure variation of this tank is P2.
After calculating P2, perform a small leak diagnosis according to the items below.
When Mode D is ended
Assign tank variations measured in Mode A and Mode B; P1 and P2, to the formula below, judge small leaks
in the system. If the measured judgment value exceeds the threshold value, it is judged to be a malfunction.
Judge as NG when the criteria below are completed and Judge as OK when not completed.

a vacuum condition increases.)
