Rodeo (2WD) V6-3165cc 3.2L SOHC (6VD1) (1993)
Chart C-3 Canister Purge Valve Check
Circuit Description
Evaporate emission canister purge is controlled by a solenoid that allows manifold and/or ported vacuum to purge the canister when energized. The
Engine Control Module (ECM) supplies a ground to energize the solenoid (purge "ON"). The purge solenoid control by the ECM is turned "ON" or
"OFF" under specific engine conditions. The purge solenoid is turned "ON" when all of the following conditions are met.
^ Data link connector is ungrounded.
^ Engine run time after start more than 20 seconds.
^ Engine coolant temperature above 60'C.
^ Vehicle speed is above 9 miles per hour.
Also, if the diagnostic test terminal is grounded with the engine stopped, the purge solenoid is energized (purge "ON").
Test Description
Numbers below refer to circled number's on the diagnostic chart.
1.
Check to see if the solenoid is opened or closed. The solenoid is normally de-energized in this step, so it should be closed.
2.
Checks to determine if solenoid was open due to electrical CKT problem or defective solenoid.
