Swirl Control Valve Control Vacuum Check Switch




1. Use vacuum pump to apply vacuum to swirl control valve control vacuum check switch as shown in figure.
2. Start engine.
3. Check voltage between terminal 2 and engine ground with CONSULT or tester.

Pressure / Voltage(V)
More than -18.7 kPa (-140 mmHg, -5.51 inHg) / Engine Ground
-18.7 to -22.7 (-140 to -170 mmHg, -5.51 to -6.69 inHg) / Engine ground or Approx. 4.8
Less than -22.7 kPa (-170 mmHg, -6.69 inHg) / Approx. 4.8

4. If NG, replace swirl control valve control vacuum check switch.
