P1165 NISSAN Meaning
The swirl control valve control vacuum control switch detects the vacuum signal at the swirl control valve and sends an “ON” or “OFF” signal to the Engine Control Module (ECM).
When vacuum is supplied to the valve, the swirl control valve control vacuum control switch sends an “OFF” signal to the ECM. The swirl control valve control vacuum control switch is not used to control the engine system; it is used for on-board diagnostics.
