General Information

Automatic Transaxle
P0717 Input/Turbine Speed Sensor 'A' Circuit No Signal - General Information

Component Location





General Description

The input (turbine) speed sensor outputs pulse-signals according to the revolutions of the input shaft of the transmission. The TCM determines the input shaft speed by counting the frequency of the pulses. This value is mainly used to control the optimum fluid pressure during shifting.

DTC Description

TCM set this code If detected short to battery, open, short to ground in this 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.
