P2759 - Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)
DESCRIPTION
Refer to P2757 P2757.
MONITOR DESCRIPTION
When an open or short in the linear solenoid valve (SLU) circuit is detected, the ECM interprets this as a fault. The ECM turns on the MIL and stores the DTC.

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
PROCEDURE
1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE 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 (Check for open):
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 connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for open):
Standard Resistance (Check for short):

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ECM Removal
3. INSPECT SHIFT SOLENOID VALVE SLU
(a) Remove 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 operating sounds.
