Yes they do.

SUBARU Automatic Transmission Solenoid A Dropping Resistor July 2, 2011. Author: Lewis Werner The SUBARU automatic transmission dropping resistor is connected in parallel with duty solenoid A. Duty solenoid A regulates the Subaru automatic transmission fluid line pressure. Like most of the transmission solenoids, duty solenoid A's duty cycle is varied by the transmission control unit (TCU) to control the line pressure.
The dropping resistor works with duty solenoid A in regulating the automatic transmission fluid line pressure. This resistor keeps a certain amount of current flow through duty solenoid A during the 'OFF' portion of its duty cycle. So in other words, duty solenoid A is never fully 'OFF'.
The dropping resistor is located on the right front shock tower, near the MPI (multi-port injection) fuel system dropping resistor. The photos at the right depict the Subaru automatic transmission dropping resistor.
If this resistor fails open, becomes disconnected, or has its wiring severed, one result might be increased shift shock. The reasoning behind this is that without the resistor in the circuit, the line pressure may be higher, since without the current passing through solenoid A during the 'OFF' portion of its duty cycle, it will tend to close further, and thus not bleed off as much pressure from the automatic transmission fluid pump.
If the resistor fails open or is disconnected, it should cause the ATF temperature lamp to flash 16 times on the next startup, since the TCU would be able to see electrically that the resistor is open.
This resistor was used on the SUBARU 4EAT phase I and 4EAT phase II automatic transmissions. It may also be used on the 5EAT though I have not confirmed it. http://www.scoobyenthusiast.com/subaru-components/subaru-automatic-transmission-solenoid-dropping-resistor

There is a locking solenoid under the plastic shroud around you shifter. When you put on your brake the solenoid is supposed to pull back to release the shifter.
The buzzing you are hearing is that solenoid trying to pull back. Going to have to replace it.

YOU CANT USE A REGULAR FUEL LINE ON POWER STEERING AS A HIGH PRESSURE HOSE.BECAUSE POWER STEERING PRESSURE IS 1000 PSI.YOU HAVE TO BUY THE POWER STEERING HIGH PRESSURE HOSE IT HAS NUMBER OF PLIES MATERIAL WEAVES TO MAKE IT STRONG.IT WAS MADE FOR POWER STEERING HIGH PRESSURE.YOU DONT HAVE A BLOCKAGE .THE HIGH PRESSURE HOSE JUST WORE OUT.REPLACE IT .IT SHOULD FIX THE PROBLEM.

Right on the top of the mass air intake where the air cleaner attaches. It has a small host running toward the front of the engine and two screws to remove it. Try cleaning it before replaceing it.

Cannovices,

Hi,
Fault codes as follows
45 Pressure Sensor Duty Solenoid (Turbo Models)
42 Idle Switch or Circuit

Those are the correct codes for a Subaru.

good luck

Dan

i have the same problem the red check engine light :(
