Examination
Check the resistance between contacts 1-2 of the valve.
- Resistance: Approx. 32 Σ (at 20°C)
Check the continuity between channels A and B using a manual vacuum pump by applying voltage from the battery directly to the valve terminals 1-2.
When applying voltage from the battery directly to pins 1 and 2: there is conductivity.
No voltage applied: no conduction.
Removing
1. Disconnect the electrical connector from the charcoal filter purge valve.
2. Disconnect the vacuum hose.
3. Remove the valve.
