DTC 0807 EVAP Can. Purge Cntrl Valve/Solenoid Valve (Circuit)
SYSTEM DESCRIPTION
This system controls the vacuum signal applied to the EVAP canister purge control valve. When the ECM detects any of the following conditions,
current does not flow through the EVAP canister purge control solenoid valve.
The solenoid valve cuts the vacuum signal so that the EVAP canister purge control valve remains closed.
-
Start switch "ON"
-
Closed throttle position
-
Low or high engine coolant temperature
-
During deceleration
-
Engine stopped
COMPONENT DESCRIPTION
EVAP canister purge control solenoid valve
The EVAP canister purge control solenoid valve responds to signals from the ECM. When the ECM sends an OFF signal, the vacuum signal (from the
intake manifold to the EVAP canister purge control valve) is cut.
When the ECM sends an ON (ground) signal, the vacuum signal passes through the EVAP canister purge control solenoid valve. The signal then reaches
the EVAP canister purge control valve.
