DTC P0773
A6E577018901225
DTC P0773 Neutral shift solenoid valve circuit malfunction (open/short)
DETECTION
CONDITION
• Open or short in neutral shift solenoid signal system (while TCM monitors solenoid output voltage, the
voltage that differs from the ON/OFF signal output by CPU in TCM is detected).
Diagnostic support note:
• This is continuous monitor (CCM).
• MIL does not illuminate.
• PENDING CODE is not available.
• FREEZE FRAME DATA is not available.
• AT warning light indication.
• DTC is stored in TCM memory.
POSSIBLE
CAUSE
• Open circuit between neutral shift solenoid valve terminal A and TCM terminal 2D
• Short to ground between neutral shift solenoid valve terminal A and TCM terminal 2D
• Short to power between neutral shift solenoid vale terminal A and TCM terminal 2D
• Neutral shift solenoid valve malfunction
• Damaged connector between neutral shift solenoid valve and TCM
• TCM malfunction
