P1137 INFINITI Meaning
The swirl control valve position sensor is installed on the intake manifold.
The sensor is connected to the front end of the swirl control valve shaft.
The sensor responds to the valve shaft movement. This sensor is a type of potentiometer that converts the swirl control valve position into output voltage and sends the voltage signal to the Engine Control Module (ECM).
