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 PCM.
When vacuum is supplied to the valve, the swirl control valve control vacuum check switch sends "OFF" signal to the PCM. The swirl control valve control vacuum check switch is not used to control the engine system, it is used for on board diagnosis.
CONSULT-II Reference Value in Data Monitor Mode
Specification data are reference values.
ON BOARD DIAGNOSIS LOGIC
Malfunction is detected when the swirl control valve control vacuum check switch remains "OFF" under specified engine conditions.
Possible Cause
- Harness or connectors
(Swirl control valve control vacuum check switch circuit is open.)
- Hoses
(Hoses are clogged or connected incorrectly.)
- Swirl control valve control solenoid valve
- Swirl control valve control vacuum check switch
- Swirl control valve actuator
