Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.

GENERAL DESCRIPTION
Purge Control Solenoid Valve Function Diagnosis
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.
Normal
•evptez – evptezha ≤ 0.4 kPa (3.0 mmHg, 0.12 inHg)
•evptezini – evptezha ≤ 0.4 kPa (3.0 mmHg, 0.12 inHg)
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.
Time Needed for Diagnosis: 16 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
