Coil Resistance (Ω)
| 18.5 - 22.5 [23°C(73.4°F)]
|
Description and operation
Installed
on the surge tank, the Purge Control Solenoid Valve (PCSV) controls the
passage between the canister and the intake manifold. This solenoid
valve 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.
