1 Sensor Throttle position sensor Description SYSTEM DESCRIPTION Throttle position Input Signal to ECM ECM function Description Actuator NIEC1534 NIEC1534S01 GI MA Ignition switch Crankshaft position sensor (POS) Camshaft position sensor (PHASE) Mass air flow sensor Start signal Engine speed Engine speed and cylinder position Amount of intake air Swirl control valve control Swirl control valve EM LC Engine coolant temperature sensor Engine coolant temperature Swirl control valve position sensor Swirl control valve position Swirl control valve has a valve portion in the intake passage of each cylinder. While idling and during low engine coolant temperature, the swirl control valve closes. Thus the velocity of the air in the intake passage increases, promoting the vaporization of the fuel and producing a swirl in the combustion chamber. Because of this operation, this system tends to increase the burning speed of the gas mixture, improve fuel consumption, and increase the stability in running conditions. Also, except when idling and during low engine coolant temperature, this system opens the swirl control valve. In this condition, this system tends to increase power by improving intake efficiency via reduction of intake flow resistance, intake flow. The swirl control valve is operated by the ECM. Throttle position sensor (Idle position) Engine coolant temperature Swirl control valve OFF Open ON Above 45 C (113 F) Below 44 C (111 F) Open Close FE CL MT AT AX SU BR ST RS BT HA COMPONENT DESCRIPTION NIEC1534S02 Swirl Control Valve NIEC1534S0201 Swirl control valve consists of actuator and valve. The valve is installed in the intake manifold, and the actuator is connected to the rear end of the valve shaft. The swirl control valve uses a step motor which has four winding phases. It operates according to the output pulse signal of the ECM. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes. When no SC EL IDX SEF407Z EC-1159
2 Description (Cont d) change in the control position is needed, the ECM does not issue the pulse signal. A certain voltage signal is issued so that the valve remains at that particular opening. Swirl Control Valve Position Sensor NIEC1534S0202 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. SEF408Z Specification data are reference values. CONSULT-II Reference Value in Data Monitor Mode NIEC1535 MONITOR ITEM CONDITION SPECIFICATION SWL C/V (B1) Engine speed: Idle Engine coolant temperature is below 44 C (111 F). Engine coolant temperature is above 45 C (113 F). 0-5 step step On Board Diagnosis Logic NIEC1536 Malfunction is detected when the target opening angle of swirl control valve controlled by ECM and the input signal from swirl control valve position sensor is not in the normal range. Possible Cause NIEC1537 Harness or connectors (The swirl control valve circuit is open or shorted.) Swirl control valve Harness or connectors (The swirl control valve position sensor circuit is open or shorted.) Swirl control valve position sensor EC-1160
3 DTC Confirmation Procedure DTC Confirmation Procedure NIEC1538 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. GI MA EM SEF174Y With CONSULT-II 1) Turn ignition switch ON and wait at least 2 seconds. 2) Select DATA MONITOR mode with CONSULT-II. 3) Start engine and let it idle for at least 10 seconds. 4) Turn ignition switch OFF and wait at least 10 seconds. 5) Turn ignition switch ON and wait at least 2 seconds. 6) Start engine and let it idle for at least 10 seconds. 7) Maintain engine speed at about 2,000 rpm for at least 10 seconds. 8) Turn ignition switch OFF, wait at least 10 seconds and then turn ON. If 1st trip DTC is detected, go to Diagnostic Procedure, EC If 1st trip DTC is not detected, go to next step. 9) Perform step 5 through 8 three times. With GST Follow the procedure With CONSULT-II above. LC FE CL MT AT AX SU BR ST RS BT HA SC EL IDX EC-1161
