SYMPTOM:
P0750-L-R SOLENOID CIRCUIT

When Monitored and Set Condition:
P0750-L-R SOLENOID CIRCUIT
When Monitored: Ignition key is turned from off or crank position to run, then every 10 secs. thereafter, or when speed ratio or pressure sw error fault is detected. All 4 solenoids (sol) are tested for continuity during vehicle operation. For sol currently energize,
Set Condition: power is momentarily interrupted, then energized. For sol not currently energized sol is momentarily energized then deenergized. Under both situations, if an inductive spike is not sensed by TCM during the continuity check, it is retested again.
