DTC P0963 (No.42): Pressure Control Solenoid Control Circuit High
Wiring Diagram
1. TCM [A]: Terminal arrangement of TCM connector (M13 engine model with VVT) (viewed from harness side)
2. Pressure control solenoid valve [B]: Terminal arrangement of TCM connector (M13 engine model without VVT) (viewed from harness side)
3. A/T      
DTC Detecting Condition and Trouble Area
DTC detecting condition Trouble area
Pressure control solenoid valve output voltage is too high comparing with TCM command value.
• Pressure control solenoid valve circuit shorted to power circuit.
• Pressure control solenoid valve malfunction
• TCM
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTC in TCM memory.
3) Start engine.
4) Keep engine running at idle speed for 10 seconds or more.
5) Check DTC.
Troubleshooting
Step Action YES NO
1
Was A/T System Check performed?
Go to Step 2.
Go to A/T System Check .
2
Check Pressure Control Solenoid Circuit for IG Short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminal “E121-2” and “E121-4” [A] or “E123-8” and “E123-11” [B].
4) If connection is OK, turn ignition switch ON and measure voltage between terminal “E121-4” [A] or “E123-11” [B] of disconnected harness side TCM connector and ground.
Is it 0 – 2 V?
Go to Step 3.
“BLU/RED” or “BLU/YEL” circuit shorted to power circuit.
3
Check Pressure Control Solenoid Valve Resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) (harness side) on automatic transmission (3).
3) Check for proper connection to solenoid at “BLU/RED” and “BLU/YEL” circuit.
4) Check resistance of pressure control solenoid.
Resistance of check pressure control solenoid valve
Resistance between pressure control solenoid valve terminals of transmission side valve body harness connector: 5.0 – 5.6 Ω (at 20 °C (68 °F))
Resistance between pressure control solenoid valve terminals of transmission side valve body harness connector and transmission body: Infinity
Is check results satisfactory?
Intermittent trouble or faulty TCM. Check for intermittent referring to Intermittent and Poor Connection Inspection . If OK, substitute a known-good TCM and recheck.
Replace pressure control solenoid valve or valve body harness.
