DTC P0741: Torque Converter Clutch Solenoid Performance (Shift Solenoid Valve SL): Procedure

WARNING: This page is about a different car, the 2013 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.

CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0741)

Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

Read the DTCs using the Techstream.

Result

Display (DTC Output)	Proceed to
Only "P0741" is output	A
"P0741" and other DTCs	B

HINT:

If any other codes besides "P0741" are output, perform the troubleshooting for those DTCs first.

OK: Go to next step
INSPECT TRANSMISSION VALVE BODY ASSEMBLY
1. Check the transmission valve body assembly. Refer to COMPONENTS .
  OK
  
  There are no foreign objects on each valve and they operate smoothly.
NG → See step 12

OK: Go to next step
INSPECT TORQUE CONVERTER ASSEMBLY
1. Check the torque converter assembly. Refer to INSPECTION .
  OK
  
  The torque converter operates normally.
NG → See step 11

OK → See step 7

INSPECT SHIFT SOLENOID VALVE SL (RESISTANCE)

Remove shift solenoid valve SL.
