INSPECT SHIFT SOLENOID VALVE SLU
DTC P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU) |
DESCRIPTION
The amount of current flow to the solenoid is controlled by the (*) duty ratio of the TCM output signal. The higher the duty ratio becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.(*) Duty RatioThe duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then Duty Ratio = A/(A + B) x 100 (%).DTC No.
| DTC Detection Condition
| Trouble Area
|
P2759
| Open or short is detected in shift solenoid valve SLU circuit for 1 second or more while driving (1-trip detection logic).
| - Open or short in shift solenoid valve SLU circuit
- Shift solenoid valve SLU
- TCM
|
MONITOR DESCRIPTION
When an open or short in a shift solenoid valve (SLU) circuit is detected, the TCM determines there is a malfunction. The TCM will turn on the MIL and store this DTC.

INSPECTION PROCEDURE
1.INSPECT TRANSMISSION WIRE (SLU) |
Remove the TCM from the transaxle.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Specified Condition 20°C (68°F)
|
11 (SLU+) - 5 (SLU-)
| 5.0 to 5.6 Ω
|
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
- Check for short:
Tester Connection
| Specified Condition
|
11 (SLU+) - Body ground
| 10 kΩ or higher
|
5 (SLU-) - Body ground
| 10 kΩ or higher
|
2.INSPECT SHIFT SOLENOID VALVE SLU |
Remove the shift solenoid valve SLU.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Specified Condition 20°C (68°F)
|
1 - 2
| 5.0 to 5.6 Ω
|
Connect a positive (+) lead through a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.
- OK:
- The solenoid makes an operating sound.
