Pressure Control Solenoid "D" Electrical
P2716 indicates an electrical fault with the Pressure Control Solenoid D circuit, which regulates transmission fluid pressure for smooth shifting. This code sets when the PCM detects a voltage or resistance issue in the solenoid's electrical circuit, preventing proper transmission pressure control.
What You Might Notice
- Check Engine Light illuminated
- Transmission slips when shifting
- Vehicle enters limp mode
- Transmission overheating
- Decreased fuel economy
Most Common Causes
- 1
Defective Pressure Control Solenoid D
The solenoid itself has failed electrically and cannot respond to PCM commands. This is the most common cause of this code.
- 2
Corroded or damaged connector
The electrical connector to the solenoid is corroded, loose, or damaged, preventing proper signal transmission from the PCM.
- 3
Faulty or damaged wiring
Wiring harness to the solenoid is broken, shorted, or has poor connections that disrupt the electrical circuit.
- 4
Dirty or contaminated transmission fluid
Contaminated fluid can cause solenoid sticking or electrical resistance issues, though this typically causes mechanical symptoms first.
How to Diagnose It
- 1
Check Defective Pressure Control Solenoid D — The solenoid itself has failed electrically and cannot respond to PCM commands. This is the most common cause of this code.
- 2
Check Corroded or damaged connector — The electrical connector to the solenoid is corroded, loose, or damaged, preventing proper signal transmission from the PCM.
- 3
Check Faulty or damaged wiring — Wiring harness to the solenoid is broken, shorted, or has poor connections that disrupt the electrical circuit.
- 4
Check Dirty or contaminated transmission fluid — Contaminated fluid can cause solenoid sticking or electrical resistance issues, though this typically causes mechanical symptoms first.
How to Fix It
- 1
Replace Pressure Control Solenoid D
Remove the transmission pan or access the solenoid based on vehicle design, disconnect the electrical connector, unbolt the solenoid, and install a new OEM or quality aftermarket unit. Refill transmission fluid if pan was removed.
- 2
Inspect and repair electrical connector
Check the solenoid connector for corrosion, bent pins, or loose fit. Clean contacts with electrical contact cleaner, straighten bent pins, or replace the connector assembly if damaged.
- 3
Test and repair wiring harness
Use a multimeter to test continuity and resistance in the wiring to the solenoid. Repair any breaks, shorts, or damaged insulation. Check that wire colors match the electrical schematic for your vehicle.
- 4
Change transmission fluid and filter
If fluid contamination is suspected, perform a complete fluid and filter change. This may resolve the code if debris is causing solenoid malfunction.
