When disconnecting the vacuum hose, make an
identification mark on it so that it can be reconnected to its
original position. |
| 1. |
Disconnect the vacuum hose from the solenoid
valve. |
| 2. |
Detach the harness
connector. |
| 3. |
Connect a vacuum pump to the nipple which is
connected to intake manifold. |
| 4. |
Apply vacuum and check when voltage is
applied to the PCSV and when the voltage is
discontinued.

FUNCTION
AND OPERATION PRINCIPLE
Purge Control Solenoid
Valve (PCSV) is installed on the surge tank and controls the passage
between the canister and the intake manifold. It is a solenoid valve and
is open when the ECM grounds the valve control line. When the passage is
open (PCSV ON), fuel vapor stored in the canister is transferred to the
intake manifold.
