ELECTRONIC CONTROLLED ENGINE MOUNT

Specification data are reference values and are measured between each terminal and ground.
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.

CONSULT-II and touch “ON/OFF” on the CONSULT-II screen.
3. Check that the motor operating sound is heard from front elec-
tronic controlled engine mount and rear electric controlled
engine mount for about 0.5 seconds according to the switching
condition of “ENGINE MOUNTING”.
OK or NG
OK >>INSPECTION END
NG >> GO TO 4.
3. CHECK OVERALL FUNCTION
Without CONSULT-II
1. Make sure that gear position is P or N.
2. Start engine and let it idle.
3. Change the engine speed from idle to more than 1,000 rpm and then return to idle (with vehicle stopped).
4. Check that the motor operating sound is heard from front electronic controlled engine mount and rear
electronic controlled engine mount for about 0.5 seconds when changing engine speed.
It is better to hear the operating sound around the left side front wheel house.

EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVEPFP:14920
DescriptionBBS0056B
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.
