CVT CONTROL SYSTEM: Torque Converter Clutch Solenoid Valve

1. The torque converter clutch solenoid valve is included in the control valve assembly.
2. The torque converter clutch solenoid valve controls TCC control valve. For detailed TCC control valve, refer to " «TRANSAXLE: COMPONENT DESCRIPTION»(ref-672632-S40923843752014112400000) ".
3. The torque converter clutch solenoid valve contains a linear solenoid valve [N/L (Normal Low) type]. NOTE: The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is proportional to this pressing force. The N/L (Normal Low) type does not produce hydraulic control when the coil is not energized.

Component Inspection (Torque Converter Clutch Solenoid Valve)

1. CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE Check the resistance between CVT unit connector terminal and ground. CVT unit - Condition Resistance (Approx.) Terminal 12 Ground CVT fluid temperature: 20°C (68°F) 5.60 - 6.60 ohms CVT fluid temperature: 50°C (122°F) 6.76 - 6.87 ohms CVT fluid temperature: 80°C (176°F) 7.47 - 7.59 ohms Is the inspection result normal? YES: INSPECTION END NO: Replace the transaxle assembly due to malfunction in the torque converter clutch solenoid valve. Refer to " «REMOVAL AND INSTALLATION»(ref-672632-S09514186012014112400000) ".
