Diagnostic Aids

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

EVAP purge solenoid resistance is 23-32 ohms.

EVAP purge solenoid is Pulse-Width Modulated (PWM). An audible clicking should be heard when the purge solenoid is commanded to 50 percent. The rate at which the solenoid cycles should increase as the commanded state is increased and decreased as the commanded state is decreased. Repeat the commands as necessary.

For intermittent conditions, refer to INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 2.2L & 3.0L VUE article.
