DTC detecting condition | Trouble area |
---|---|
Voltage of timing solenoid valve TCM terminal is high although TCM is commanding timing solenoid valve to turn OFF. |
•
Timing solenoid valve circuit open or shorted to power circuit.
• Timing solenoid valve malfunction. • TCM |

Check Timing Solenoid Valve Circuit for IG Short
1)
Turn ignition switch ON and measure voltage between terminal “E121-14” [A] or “E123-10” [B] of harness side TCM connector and ground.
Is it 0 – 1 V?
|
Go to Step 3.
|
“WHT/GRN” circuit shorted to power circuit.
|
3 |
Check Timing Solenoid Valve Circuit for Open
1)
Measure resistance between terminal “E121-14” [A] or “E123-10” [B] of disconnected harness side TCM connector and ground.
Is it 11 – 15 V at 20 °C (68 °F)?
|
Intermittent trouble or faulty TCM.
Check for intermittent referring to
Intermittent and Poor Connection Inspection
.
If OK, substitute a known-good TCM and recheck.
|
Go to Step 4.

Check Timing Solenoid Valve Resistance
1)
Turn ignition switch OFF.
2)
Disconnect valve body harness connector on transmission (1).
3)
Check for proper connection to solenoid valve at “WHT/RED” circuit.
|
“WHT/RED” circuit open.
|
Replace timing solenoid valve or lead wire.
