Shift Solenoid Valve Circuit Check

SHIFT SOLENOID VALVE CIRCUIT CHECK
1. With ignition switch turned OFF, disconnect PCM coupler.





2. Bring ohmmeter probes in touch with coupler terminals from harness side and measure each resistance.
Resistance between C21-6 and C21-1
(Shift solenoid-A, direct clutch) : 8 - 20 ohms
Resistance between C21-5 and C21-1
(Shift solenoid-B, 2nd brake) : 8 - 20 ohms
If resistance is out of specification, check shift solenoid itself for resistance (referring to Step 3 of DTC P0753/P0756 Diag. Flow Table) and wire harness for open or short.
If resistance is within specification, proceed to step 3).





3. Disconnect shift solenoid valve coupler from harness.
4. Apply 12 V to each terminal in solenoid valve coupler and check to be sure that a click sound is heard from each of shift solenoid A and B.
If no click sound is heard, check lead wire and connections in oil pan, and then replace applicable shift solenoid A or B if wire and connections are in good condition.
If click sound is heard from each of shift solenoids A and B. shift solenoid electrical circuits are in good condition. Proceed to "Shift Solenoid Valve Check".
