P2759 - Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

DESCRIPTION

Refer to the system description for DTC P2757 P2757.





MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLU circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and stores the DTC.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

PROCEDURE

1. INSPECT TRANSMISSION WIRE (SLU)





(a) Disconnect the transmission wire connector from the transaxle.

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

Standard resistance:





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

Standard resistance (Check for short):





NG -- INSPECT SHIFT SOLENOID VALVE SLU
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)





(a) Connect the transmission wire connector to the transaxle.

(b) Disconnect the ECM connectors.

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

Standard resistance:





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

Standard resistance (Check for short):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE ECM (for 2ZR-FE) Removal

3. INSPECT SHIFT SOLENOID VALVE SLU





(a) Remove the shift solenoid valve SLU.

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

Standard resistance:





(c) 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 -- REPLACE SHIFT SOLENOID VALVE SLU Disassembly

OK -- REPAIR OR REPLACE TRANSMISSION WIRE Removal
