5A-63 Automatic Transmission/Transaxle:

DTC P0963: Pressure Control Solenoid "A" Control Circuit High

Wiring Diagram
Refer to "DTC P0962: Pressure Control Solenoid "A" Control Circuit Low".
DTC Detecting Condition and Trouble Area
DTC Detecting Condition
Pressure control solenoid valve output voltage is too high
comparing with TCM command value.
(1 driving cycle detection logic)
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine.
4) Keep engine running at idle speed for 10 seconds or more.
5) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check pressure control solenoid valve circuit for power
supply short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminal "E92-2"
and "E92-4".
3) If connection is OK, turn ignition switch ON and measure
voltage between terminal "E92-2" of disconnected
harness side TCM connector and ground.
Is it 0 – 2 V?
3 Inspection pressure control solenoid valve
1) Inspection pressure control solenoid valve referring to
"Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B,
TCC Pressure Control Solenoid and Pressure Control
Solenoid Inspection".
Is check results satisfactory?
Action
Trouble Area
• Pressure control solenoid valve circuit shorted
to power circuit.
• Pressure control solenoid valve malfunction.
• TCM
Yes
Go to Step 2.
Go to Step 3.
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to "Intermittent
and Poor Connection
Inspection in Section
00". If OK, substitute a
known-good TCM and
recheck.
