Pressure Control Solenoid "D" Control Circuit Range/Performance
P2719 indicates the transmission's Pressure Control Solenoid D is not responding correctly to PCM commands or is experiencing an electrical control circuit malfunction. This solenoid regulates transmission fluid pressure and when it fails, the transmission cannot shift properly and may enter limp mode to protect itself.
What You Might Notice
- Check Engine Light activated
- Transmission slips when shifting
- Transmission shifts hard or bangs into gear
- Increased fuel consumption
- Transmission overheating
Most Common Causes
- 1
Faulty Pressure Control Solenoid D
The solenoid itself has failed electrically or mechanically, preventing proper pressure regulation. This is the most common cause of this code.
- 2
Wiring or Connector Issues
Corroded, damaged, or loose wiring to the solenoid control circuit or a faulty solenoid connector can prevent proper electrical signal transmission.
- 3
Low or Dirty Transmission Fluid
Contaminated or insufficient transmission fluid can affect solenoid operation and cause pressure control problems.
- 4
PCM or TCM Malfunction
A faulty transmission control module or engine control module may send incorrect signals to the solenoid or fail to recognize proper solenoid feedback.
How to Diagnose It
- 1
Check Faulty Pressure Control Solenoid D — The solenoid itself has failed electrically or mechanically, preventing proper pressure regulation. This is the most common cause of this code.
- 2
Check Wiring or Connector Issues — Corroded, damaged, or loose wiring to the solenoid control circuit or a faulty solenoid connector can prevent proper electrical signal transmission.
- 3
Check Low or Dirty Transmission Fluid — Contaminated or insufficient transmission fluid can affect solenoid operation and cause pressure control problems.
- 4
Check PCM or TCM Malfunction — A faulty transmission control module or engine control module may send incorrect signals to the solenoid or fail to recognize proper solenoid feedback.
How to Fix It
- 1
Replace Pressure Control Solenoid D
Remove and replace the faulty solenoid with a new OEM or quality aftermarket part. Ensure proper installation and reconnection of all electrical connectors.
- 2
Inspect and Repair Wiring
Check the solenoid control circuit wiring harness for corrosion, damage, or loose connections. Repair or replace damaged wiring and clean corroded connectors.
- 3
Change Transmission Fluid and Filter
Drain old transmission fluid and replace the filter to remove contaminants that may be affecting solenoid performance and pressure control.
- 4
Reprogram or Replace TCM
If wiring and solenoid are good, have the transmission control module reprogrammed or replaced. This should only be done after other causes are ruled out.
