Automatic Transaxle
P0756 Shift Control Solenoid Valve 'B' Performance or Stuck Off (SOL 2 ) - General Information

Component Location





General Description

Shift control solenoid valve is supply oil pressure usually,TCM output "ON" signal to solenoid valve then oil pressure not supplied to Clutch "B". Solenoid 4 (Clutch E & Brake D), Solenoid 5 (Line pressure) are same type solenoid valve.
If electrical power source not supplied to all of solenoid valve, the oil pressure supplied to 3 solenoid valves and shift gear is fixed at 3rd gear as mechanical operation.

DTC Description

TCM set this code If detected short to ground / open for solenoid valve circuit. (MIL ON : 2 driving Cycle)

DTC Detecting Condition





CAUTION :
1. The function with the higher priority will always take precedence. However, a low-priority is not overruled by a higher priority function.
2. Functions from different priority categories can also run in parallel. It is important to note which function will take precedence in this case.
3. In such an event it is possible for a substitute function with low priority not be carried out if a second, higher-priority function is present. This has been taken into account when compiling the priority list and is international.
4. The mechanical emergency run function must always have the highest priority, since from the electrical standpoint it is the only safe condition.
