P1165

COMPONENT DESCRIPTION
The swirl control valve control vacuum check switch detects vacuum signal to the swirl control valve and sends "ON" or "OFF" signal to the ECM.
When vacuum is supplied to the valve, the swirl control valve control vacuum check switch sends "OFF" signal to the ECM. The swirl control valve control vacuum check switch is not used to control the engine system, it is used for on board diagnosis.




ECM TERMINALS AND REFERENCE VALUE
Specification data are reference values and are measured between each terminal and (43) (ECCS ground).

DIAGNOSTIC PROCEDURE

COMPONENT INSPECTION
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.

Swirl Control Valve Control Solenoid Valve
Check solenoid valve air passage continuity.




Condition / Air passage continuity between (A) and (B) / Air passage continuity between (A) and (C)
12V current supply between terminals (1) and(2) / Yes / No
No supply / No / Yes

If NG, replace solenoid valve.
