Exhaust Gas RECIRCULATION Solenoid Valve (Optima & MAGENTIS (CANADIAN) 2.4L)
NOTE:
Only component testing procedure is covered. For Exhaust Gas Recirculation (EGR) solenoid valve system and circuit testing procedure, see appropriate SELF-DIAGNOSTICS article.
NOTE:
For EGR solenoid valve removal and installation, see EXHAUST GAS RECIRCULATION SOLENOID VALVE under EMISSION SYSTEMS & SUB-SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION article.
- Disconnect EGR solenoid valve 2-pin harness connector. Check resistance between EGR solenoid valve terminals. See test procedure No. 1 in Fig 1. Resistance should be 24-28 ohms at 68°F (20°C). If resistance is not as specified, replace EGR solenoid valve. If resistance is as specified, go to next step.
- Using a fused jumper wire, connect battery voltage to terminal No.1, energize EGR solenoid by grounding terminal No. 2. Listen for operational sound (click). Seetest procedure No. 2 in Fig 1. If operational sound is heard, go to next step. If operational sound is not heard, replace EGR solenoid valve.
- Connect vacuum pump to port "A" of EGR solenoid valve. While EGR solenoid valve is operated by battery power, Apply vacuum. See test procedure No. 3 in Fig 1. If vacuum is not held, EGR solenoid valve is operating properly. If vacuum is held, replace EGR solenoid valve.
