P1137
COMPONENT 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 ECM.
CONSULT-II Reference Value In Data Monitor Mode:
ON BOARD DIAGNOSIS LOGIC
Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM.
Possible Cause
- Harness or connectors
(Swirl control valve position sensor circuit is open or shorted.)
- Swirl control valve position sensor
- Harness or connectors
(Swirl control valve circuit is open or shorted.)
- Swirl control valve
DTC Confirmation Procedure
NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.
With CONSULT-II
1. Turn ignition switch "OFF" and wait at least 10 seconds.
2. Turn ignition switch "ON".
3. Select "DATA MONITOR" mode with CONSULT-II and wait at least 5 seconds.
If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
With GST
Follow the procedure "WITH CONSULT-II" above.

ECM TERMINALS AND REFERENCE VALUE MEASURED BETWEEN EACH TERMINAL AND GROUND.
CAUTION: DO NOT USE ECM GROUND TERMINALS WHEN MEASURING INPUT/OUTPUT VOLTAGE. DOING SO MAY RESULT IN DAMAGE TO THE ECM'S TRANSISTOR. USE A GROUND OTHER THAN ECM TERMINALS, SUCH AS THE GROUND.
