The P2819 fault code indicates an issue with the Pressure Control Solenoid H circuit in your vehicle's transmission system. The Pressure Control Solenoid is responsible for regulating hydraulic pressure based on input from the vehicle's computer, thus controlling the shifting of gears. Malfunctions in this system can lead to improper shifting, reduced fuel efficiency, and potentially damage the transmission.

What are the symptoms of the P2819 code?

If your vehicle is experiencing a P2819 code, you may notice:

• Harsh or inconsistent shifting
• Check Engine Light activated
• Slipping or delayed engagement of gears
• Transmission overheating
• Poor acceleration or power delivery

What causes the P2819 code?

Common causes of the P2819 fault code include:

• Faulty Pressure Control Solenoid H
• Open or short circuit in the wiring harness
• Connector issues (corrosion, looseness)
• Transmission fluid issues (contamination, low fluid levels)
• Malfunctioning Transmission Control Module (TCM)
• Electrical short circuits in the circuit leading to the solenoid

How to fix P2819?

To resolve a P2819 fault code, follow these steps:

1. Inspect the wiring and connectors leading to the Pressure Control Solenoid H for any signs of damage or corrosion.
2. Check the transmission fluid level and condition. Replace if necessary.
3. Test the Pressure Control Solenoid H for proper operation and replace if faulty.
4. Examine the TCM for any faults or malfunctions, and perform a reset if needed.
5. Clear the fault code using an OBD-II scanner and test drive the vehicle to ensure the issue is resolved.
