COMPONENT DESCRIPTION |
Pressure Control Solenoid Valve
PCV controls the fuel tank pressure to be equal to the atmospheric air pressure.Normally, the solenoid is set to OFF. And the valve opens and closes mechanically in accordance with the pressure difference between tank and atmospheric air, or tank and canister.
The valve is forcibly opened by setting the solenoid to ON at the time of diagnosis.

DIAGNOSTIC METHOD |
Purge control solenoid valve open malfunction diagnosis
DTCP0457 Evaporative Emission Control System Leak Detected (fuel cap loose/off)
Purpose of Mode Z
When performing the leakage diagnosis of EVAP system, CPC has to operate normally. Therefore, mode Z is used to diagnose the CPC open fixation.
If the CPC open fixation trouble is detected, the EVAP system leakage diagnosis is cancelled.
Diagnostic method
CPC functional diagnosis is performed by monitoring the tank pressure in Mode Z.
Normality Judgment
Judge OK when the following criteria are satisfied in 3 seconds after Mode Z started, and change to Mode A.

Leak Diagnosis
DTCP0442 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 presence
of leakage from the speed at which the tank internal pressure returns
to atmospheric pressure.
|
• |
The diagnosis is divided into the following
five phases.
|
Mode A: (Estimation of evaporation gas yield)
The amount of change of tank pressure (P1) in Mode A is calculated. After calculating P1, change to Mode B.
Mode B: (Seal negative pressure)
Introduce the negative pressure in the intake manifold to the tank.
Approx. 0 → −1.4 kPa (0 → −10.5 mmHg, 0 → −0.41 inHg)
When the pressure above (desired negative pressure) is reached, Mode C is entered.
In this case, if the tank pressure does not become the desired negative pressure, judge that there is a large leakage in the system, finish the Evap. diagnosis when judging large leak (10 or 25 seconds).
Abnormality Judgment
Judge NG (large leak) when the criteria below are completed in the specified time.

|
Mode C: (Check increasing pressure)
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 calculation.)
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.
Tank pressure when P2 calculation started | Time for immediate OK judgment |
−1.3
kPa (−9.75 mmHg, −0.38 inHg)
|
15 seconds
|
Mode D: (Measurement of negative pressure changes)
Monitor the pressure variation in the tank in Mode Z. In this case, the tank pressure increases, that is, the pressure becomes as high as the atmospheric air pressure, because evaporator is generated. However, if any leakage exists, the pressure increases additionally in proportion to this leakage. The pressure variation of this tank is P2.
After calculating P2, perform following small leak diagnosis.
After Mode D
Assigning P1 and P2, which are tank variations measured in Mode A and Mode B, to the formula below, judge the small leakage of the system. If the measured judgment value exceeds the threshold value, it is judged to be malfunction.
Abnormality Judgment
Judge NG when the criteria below are completed. Judge OK when not completed and clear the NG.

Leak diagnosis
DTCP0456 Evaporative Emission Control System Leak Detected (very small leak)
Diagnostic method
• |
The diagnostic method consists of creating
a sealed vacuum in the fuel tank and then determining the presence
of leakage from the speed at which the tank internal pressure returns
to atmospheric pressure.
|
• |
The diagnosis is divided into the following
five phases.
|
Mode A: (0 point correction)
Wait until the tank pressure returns to 0 point (near 0 mmHg) when tank pressure is high. Then change to Mode B. If the tank pressure does not return to 0 point in the specified time, cancel the diagnosis.
Mode B: (Negative pressure introduction)
Introduce the negative pressure in the intake manifold to the tank.
Approx. 0 → −2.0 kPa (0 → −15 mmHg, 0 → −0.59 inHg)
When the pressure above (desired negative pressure) is reached, Mode C is entered.
In this case, if the tank pressure does not become the desired negative pressure, cancel the diagnosis.
Mode C: (Holding negative pressure)
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 calculation.)
Change to Mode D when the tank pressure returns to the start level of P2 calculation, or when spending the specified time.
Mode D: (Calculation of negative pressure variation)
By monitoring the tank pressure at Mode D, calculate the pressure variation (P2) and measure the time (evpdset) it takes the tank pressure to return to the detection completing pressure of P2. Then change to Mode E. When the tank pressure does not return to the detection completing pressure of P2 in the specified time, make advanced OK judgment or cancel the diagnosis according to P2 value.
