CVT CONTROL SYSTEM: Torque Converter Clutch Solenoid Valve
- The torque converter clutch solenoid valve is installed to control valve.
- The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information about the torque converter clutch control valve, refer to " «TRANSAXLE: COMPONENT DESCRIPTION»(ref-675588-S16789116262014120500000) ".
- The torque converter clutch solenoid valve utilizes 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.
TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR
| Control | Engine output is controlled according to a vehicle speed while reversing the vehicle. |
|---|
| Vehicle behavior in control | Power performance may be lowered while reversing the vehicle. |
| Normal return condition | Torque returns to normal by positioning the selector lever in a range other than "R" position. |

Component Inspection (Torque Converter Clutch Solenoid Valve)
- CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE Check resistance between CVT unit connector terminal and ground. CVT unit - Condition Resistance (Approx.) Terminal 8 Ground CVT fluid temperature: 20°C (68°F) 6.1 ohms CVT fluid temperature: 50°C (122°F) 6.9 ohms CVT fluid temperature: 80°C (176°F) 7.7 ohms Is the inspection result normal? YES: INSPECTION END NO: There is a malfunction of torque converter clutch solenoid valve. Replace transaxle assembly. Refer to " «REMOVAL AND INSTALLATION»(ref-675588-S04049217762014120500000) ".
