DTC detecting condition | Trouble area |
---|---|
Voltage of shift solenoid valve TCM terminal is high although TCM is commanding shift solenoid to turn ON. |
•
Shift solenoid valve circuit open or shorted to power circuit.
• Malfunction of shift solenoid valve • TCM |

Check Shift Solenoid Valve Resistance
1)
Turn ignition switch OFF.
2)
Disconnect valve body harness connector (1) on automatic transmission (4).
3)
Check for proper connection to solenoid at “RED/GRN” (for shift solenoid valve-A (No.1) (2)) or “YEL/GRN” (for shift solenoid valve-B (No.2) (3)) circuit.
Check resistance of solenoid valve.
Resistance of shift solenoid valve
Resistance between shift solenoid valve-A (No.1) terminal and transmission: 11 – 15 Ω at 20 °C (68 °F)
Resistance between shift solenoid valve-B (No.2) terminal and transmission: 11 – 15 Ω at 20 °C (68 °F)
Is check results satisfactory?

Go to step 3.
|
Replace applicable shift solenoid valve or valve body harness.

Check Shift Solenoid Valve Circuit for Ground Short
1)
Disconnect TCM connectors.
2)
Check for proper connection to TCM at terminal “E121-16” [A] or “E123-4” [B] (for shift solenoid valve-A (No.1)) or “E121-15” [A] or “E123-3” [B] (for shift solenoid valve-B (No.2)).
3)
If connection is OK, check continuity between terminal “E121-16” [A] or “E123-4” [B] (for shift solenoid valve-A (No.1)) or “E121-15” [A] or “E123-3” [B] (for shift solenoid valve-B (No.2)) of disconnected harness side TCM connector and ground.
Is continuity indicated?

DTC P0973: “RED/GRN” circuit shorted to ground.
DTC P0976: “YEL/GRN” circuit shorted to ground.
|
Intermittent trouble or faulty TCM. Check for intermittent referring to
Intermittent and Poor Connection Inspection
. If OK, substitute a known-good TCM and recheck.
