DTC P0962 (No.41): Pressure Control Solenoid Control Circuit Low
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 low comparing with TCM command value.
• Pressure control solenoid valve circuit open or shorted to ground.
• Malfunction of pressure control solenoid valve
• 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 30 seconds or more.
5) Stop vehicle and 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 Valve Resistance
1) Turn ignition switch OFF
2) Disconnect valve body harness connector (1) on automatic transmission (2).
3) Check for proper connection to solenoid at “BLU/RED” and “BLU/YEL” circuit.
4) Check resistance of pressure control solenoid.
Resistance of 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?
Go to Step 3.
Replace pressure control solenoid valve or valve body harness.
3
Check Pressure Control Solenoid Valve Circuit for Ground Short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminals “E121-2” and “E121-4” [A] or “E123-8” and “E123-11” [B].
If connection is OK, check continuity between terminal “E121-4” [A] or “E123-8” [B] of disconnected harness side TCM connector and ground.
Is continuity indicated?
“BLU/RED” or “BLU/YEL” circuit shorted to ground.
Go to Step 4.
4
Check Pressure Control Solenoid Valve Circuit for Open
1) Check resistance between terminals “E121-2” and “E121-4” [A] or “E123-8” and “E123-11” [B] of disconnected harness side TCM connector.
Is it infinity?
“BLU/RED” or “BLU/YEL” circuit open.
Intermittent trouble or faulty TCM. Check for intermittent referring to Intermittent and Poor Connection Inspection . If OK, substitute a known-good TCM and recheck
