Possible causes
– Faulty Swirl Control Valve Control Position Sensor
– Swirl Control Valve Control Position Sensor harness is open or shorted
– Swirl Control Valve Control Position Sensor circuit poor electrical connection
– Faulty Swirl Control Valve
– Swirl Control Valve Control Position Sensor harness is open or shorted
– Swirl Control Valve Control Position Sensor circuit poor electrical connection
– Faulty Swirl Control Valve
When is the code detected?
An excessively low or high voltage from the sensor is sent to Engine Control Module (ECM).
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
P1137 INFINITI Description
Swirl control valve position sensor is installed on the intake manifold.
The sensor is connected to the front end of the valve shaft of the swirl control valve.
The sensor responds to the valve shaft movement. This sensor is a kind of potentiometer which transforms the swirl control valve position into output voltage, and emits the voltage signal to the Engine Control Module (ECM).
