DTC P2757: Torque Converter Clutch Pressure Control Solenoid Performance (Shift Solenoid Valve SLU) [10/2015 - ]: Procedure
- CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2757)
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / ECT / Trouble Codes.
- Read the DTCs using the Techstream.
Result
Display (DTC output) Proceed to Only DTC P2757 is output A DTC P2757 and other DTCs are output B HINT:
If any other codes besides "P2757" are output, perform troubleshooting for those DTCs first.
Result:
B
GO TO DTC CHART
(Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2015 - ] )
Result:
A
See step 2
- INSPECT SHIFT SOLENOID VALVE SLU
- Remove 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 TEXT IN ILLUSTRATION*1 Shift Solenoid Valve SLU - Connect a battery positive (+) lead with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.
OK
Valve moves and makes an operating sound.
