• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0750 SHIFT SOLENOID/V A” with CONSULT-III or 4th judgement flicker without
CONSULT-III is detected when TCM detects an improper voltage drop when it tries to operate the solenoid
valve.
Possible CauseINFOID:0000000001703277
• Harness or connector
(The solenoid circuit is open or shorted.)
• Shift solenoid valve A
DTC Confirmation ProcedureINFOID:0000000001703278
