EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVEPFP:14920
DescriptionBBS005IA
SYSTEM DESCRIPTION
*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass pas-
sage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canis-
ter. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic ProcedureBBS005ID
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canister.
3. Turn ignition switch ON, and select “PURG VOL CONT/V” in
“ACTIVE TEST” mode with CONSULT-II.
4. Start engine and let it idle.
5. Change the valve opening percentage with touching “Qu” or
“Qd” on CONSULT-II screen, and check for vacuum existence at
the EVAP purge hose under the following conditions.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canis-
ter.
3. Start engine and let it idle for at least 80 seconds.
4. Check for vacuum existence at the EVAP purge hose under the
following conditions.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK EVAP CANISTER
