The P1138 code is detected when the target opening angle of swirl control valve controlled by Engine Control Module (ECM) and the input signal from swirl control valve position sensor is not in the normal range.
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
