DTC P2759: Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU): Procedure
WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT TRANSMISSION WIRE (SLU)

- Disconnect the transmission wire connector from the transaxle.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 4 (SLU+) - 9 (SLU-) 20°C (68°F) 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 Condition Specified Condition 4 (SLU+) - Body ground Always 10 kΩ or higher 9 (SLU-) - Body ground Always ↑
NG → See step 3
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)
- Connect the transmission wire connector to the transaxle.
- Disconnect the ECM connectors.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B29-54 (SLU+) - B29-53 (SLU-) 20°C (68°F) 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 Condition Specified Condition B29-54 (SLU+) - Body ground Always 10 kΩ or higher B29-53 (SLU-) - Body ground Always ↑
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 5
- INSPECT SHIFT SOLENOID VALVE SLU
Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
- Remove the shift solenoid valve SLU.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 5.0 to 5.6 Ω - Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.
OK
The solenoid makes an operating sound.
NG → See step 6
OK → See step 4
- REPAIR OR REPLACE TRANSMISSION WIRE. Refer to REMOVAL
- REPLACE ECM (for 2ZR-FE). Refer to REMOVAL
- REPLACE SHIFT SOLENOID VALVE SLU. Refer to DISASSEMBLY
