DTC P0761: Shift Solenoid "C" Performance (Shift Solenoid Valve S3) [08/2017 - 08/2019]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
5. Read the DTCs using the Techstream.
   RESULT
   
   

   Result	Proceed to
   Only P0761 is output	A
   P0761 and other DTCs are output	B

   HINT: 

   If any other codes besides P0761 are output, perform troubleshooting for those DTCs first.

Result: 

B 

GO TO DTC CHART 

Refer to:DIAGNOSTIC TROUBLE CODE CHART [08/2017 - 08/2019] )

Result: 

A 

See step  2

HINT: 

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

1. Remove the test plug on the transmission case center right side and connect SST.

   • SST: 09993-19015 
     1. 09993-00010
     2. 09993-00040
2. Connect the Techstream to the DLC3.
3. Start the engine and warm it up.
4. Measure the line pressure with SST.
5. Turn the Techstream on.
6. Enter the following menus: Powertrain / Engine and ECT / Active Test.
7. According to the display on the Techstream, perform the Active Test.
8. Measure the line pressure.
   ENGINE AND ECT
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Activate the Solenoid (SLT)*	Operate the shift solenoid SLT and raise line pressure	ON or OFF HINT:  OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands SLT solenoid to turn OFF) ON: No action (normal operation)	[Vehicle Condition] Vehicle stopped Engine idling

   HINT: 

   *: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the Hydraulic Test. Refer to: HYDRAULIC TEST [08/2015 - 08/2019] ) as well. Please note that the pressure values in the Active Test and Hydraulic Test are different.

   OK

   The line pressure changes as specified when performing the Active Test.

Result: 

NG 

REPLACE SHIFT SOLENOID VALVE SLT 

Refer to:PROCEDURE - Step 3 )

Result: 

OK 

See step  3

1. Remove the shift solenoid valve S3.

2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Shift solenoid valve S3 connector terminal - Shift solenoid valve S3 body	20°C (68°F)	11 to 15 Ω

3. Connect the battery positive (+) lead to the terminal of the solenoid valve connector, and the negative (-) lead to the solenoid valve body. Then check that the valve moves and makes an operating noise.

   OK

   Valve moves and makes an operating noise.

Result: 

NG 

REPLACE SHIFT SOLENOID VALVE S3 

Refer to:PROCEDURE - Step 9 )

Result: 

OK 

See step  4

1. Check the transmission valve body assembly.

   OK

   There are no foreign objects on each valve.

Result: 

OK 

REPAIR OR REPLACE AUTOMATIC TRANSMISSION ASSEMBLY

Result: 

NG 

REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSEMBLY
