What Does P2826 Mean?
The transmission control module has detected abnormally low voltage in the control circuit for Pressure Control Solenoid J. This electrical fault prevents proper solenoid operation and transmission pressure control.
Common Causes
30%
Short to ground in solenoid J control circuit wiring
25%
Failed pressure control solenoid J with internal short
20%
Corroded or damaged solenoid connector causing low resistance path
15%
Transmission fluid intrusion into solenoid connector
10%
Faulty transmission control module output driver
Diagnostic Steps
1
Step 1: Disconnect solenoid J connector and measure resistance from control wire to ground; should show infinite resistance
2
Step 2: Inspect solenoid connector for fluid contamination, corrosion, or damaged pins
3
Step 3: Measure solenoid J internal resistance and compare to manufacturer specifications
4
Step 4: Check for chafed or pinched wiring between TCM and solenoid J
5
Step 5: Test TCM output voltage at solenoid connector during commanded operation
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The transmission control module has detected abnormally low voltage in the control circuit for Pressure Control Solenoid J. This electrical fault prevents proper solenoid operation and transmission pressure control.
The most common cause of P2826 (Pressure Control Solenoid "J" Control Circuit Low) is: Short to ground in solenoid J control circuit wiring
Typical repair costs for P2826 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Can cause transmission to operate in limp mode, harsh shifts, or loss of certain gears. Vehicle may be unsafe for highway driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2826 to identify the root cause.
