What Does P2819 Mean?
The transmission control module has detected an electrical fault in the pressure control solenoid H circuit. This is a general electrical code indicating problems with the solenoid, wiring, or control module that prevent proper solenoid operation.
Common Causes
35%
Open or shorted solenoid coil windings
25%
Damaged wiring harness or broken wires in solenoid circuit
20%
Corroded or damaged solenoid connector pins
15%
Transmission control module driver circuit failure
5%
Ground circuit open or high resistance
Diagnostic Steps
1
Step 1: Perform resistance test on solenoid H; compare readings to manufacturer specifications
2
Step 2: Inspect solenoid connector for bent pins, corrosion, oil intrusion, or loose connections
3
Step 3: Test continuity in wiring harness from TCM connector to solenoid connector
4
Step 4: Check ground circuit continuity and resistance to chassis ground
5
Step 5: Perform voltage drop test on power and ground circuits while commanding solenoid with scan tool
Estimated Repair Cost
$200 - $1,600
Parts + labor, varies by vehicle and location
The transmission control module has detected an electrical fault in the pressure control solenoid H circuit. This is a general electrical code indicating problems with the solenoid, wiring, or control module that prevent proper solenoid operation.
The most common cause of P2819 (Pressure Control Solenoid "H" Electrical) is: Open or shorted solenoid coil windings
Typical repair costs for P2819 range from $200 to $1,600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission may not shift properly and could enter fail-safe mode with limited functionality. Avoid aggressive driving and repair promptly to prevent further damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2819 to identify the root cause.
