Electrical connection for the pressur control

basically all of the codes refer to the solenoid
check all wiring and connections for corrosion, check the condition of the oil as it may be well overdue for a change
remember that solenoids get the power from the transmission control module(TCM), the Transmission ratio(TR) sensor m) and the VSS ( vehicle speed sensor )
all of these play a part in making the solenoid work at h right time
I would suggest that you spend time discussing the problem and the codes with a professional transmission repair shop just to expand on the manuals limited information

Possible causes
- Clutch Pressure Control Solenoid Valve harness is open or shorted
- Clutch Pressure Control Solenoid Valve circuit poor electrical connection
- Faulty Clutch Pressure Control Solenoid Valve

Has to do with the solenoid or wiring to the solenoid inside the transmission. You should have the problem addressed at a transmission shop.

Possible causes P406 include EGR Valve clogged, dirty or leaky
- EGR valve damaged/defective
- EGR volume control solenoid valve
- EGR temperature sensor and circuit
- EGR volume control solenoid valve harness is open or shorted
- EGR volume control solenoid valve circuit poor electrical connection
Possible causes P0108 - Faulty Manifold Absolute Pressure sensor
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

code p2716 refers to transmission fluid pressure (TFP) solenoid D --electrical=== causes wiring---TFP solenoid
check all connections are clean and tight . replace the solenoid.

1 You have a bad O2 sensor.
2 I think this second one may mean Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid
- Pressure Control Solenoid harness is open or shorted
- Pressure Control Solenoid circuit poor electrical connection

P1782 DODGE - 2/4-OD Pressure Switch Circuithttp://engine-codes.com/p1782_dodge.htmlForum CodePossible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shockP1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.

DTC P2716 - Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

If you need to test this electrical components and wiring. Tell me if you need the TSB about this DTC.

have the code checked especially if the car is out of warranty. If it is still under warranty take the car to the dealership . The Pressure Control Solenoid determines the quality and accuracy of the shift points and if you let it go the transmission will not shift properly after a period of time. The pressure control solenoid is used by the PCM to raise the mainline hydraulic pressure during high throttle - this increases the holding force on the clutches and bands and prevents slipping. The pressure control solenoid is controlled by pulses from the PCM and this in turn operates the boost valve insde the valve body.

The problem could be either in the PCM or it could be an electrical problem with the solenoid. As suggested it should be diagnosed by a transmission tech. They can check if the PCM is good by looking at the pulses with an oscilloscope at the connector and they should also be able to test the continuity of the solenoid. If the solenoid is faulty the valve body will need to be removed and the solenoid replaced.
good luck

There is a technical service bulletin to correct this condition. Replacement of the car's Electronic Control Unit (the computer) will cure this. Take it to a Toyota dealer and have them replace it for free.
