A/T CONTROL SYSTEM: Torque Converter Clutch Solenoid Valve
- The torque converter solenoid valve is installed to control valve.
- The torque converter solenoid valve controls the lock-up control valve. For information about the lock-up control valve, refer to " «A/T CONTROL SYSTEM: COMPONENT DESCRIPTION»(ref-605946-S20131144682014032500000) ".
- The high clutch solenoid valve utilizes a linear solenoid valve [N/H (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 oil pressure when the coil is not energized.
TORQUE-DOWN CONTROL WHEN CONTINUOUS STALL OCCURS IN D POSITION
If the accelerator pedal is continually depressed for a certain length of time when the selector lever is in the "D" position and the vehicle is parked, the engine output is limited for protecting the transaxle.
| Operation detection conditions | The following conditions continue for 20 seconds or more Selector lever is in the "D" position or "R" position and the vehicle is stopped and Engine speed: 2, 300 - 2, 850 RPM |
|---|
| Control when activated | Limits engine output |
| Recovery condition | Selector lever is shifted to a position other than "D" or "R" or The accelerator pedal is released |
| Vehicle behavior | Decreased starting performance Engine speed hunching when the accelerator pedal is depressed |

Component Inspection (Torque Converter Clutch Solenoid Valve)
- CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE Check the resistance between the A/T unit connector terminal and ground. A/T unit connector Ground Condition Resistance Terminal 18 Ground A/T fluid temperature: 20°C (68°F) Approx. 6.1 ohms A/T fluid temperature: 50°C (122°F) Approx. 6.9 ohms A/T fluid temperature: 80°C (176°F) Approx. 7.7 ohms Is the check result normal? YES: INSPECTION END NO: There is a malfunction of the torque converter clutch solenoid valve. Replace the transaxle assembly. Refer to " «REMOVAL AND INSTALLATION»(ref-605946-S11860495092014032500000) ".
