What Does P2828 Mean?
The transmission control module has detected a general malfunction with Pressure Control Solenoid K. This is a non-specific code indicating the solenoid is not functioning properly, which affects transmission hydraulic pressure control.
Common Causes
35%
Failed or worn pressure control solenoid K
25%
Dirty or contaminated transmission fluid affecting solenoid operation
20%
Electrical connector corrosion or poor connection at solenoid K
15%
Wiring harness damage between TCM and solenoid K
5%
Faulty transmission control module
Diagnostic Steps
1
Step 1: Verify transmission fluid level and condition; change fluid if contaminated or degraded
2
Step 2: Inspect solenoid K connector for corrosion, damage, or loose terminals
3
Step 3: Measure solenoid K resistance and compare to specifications
4
Step 4: Monitor solenoid K operation using scan tool with live data during test drive
5
Step 5: Perform voltage and ground tests on solenoid K circuit
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The transmission control module has detected a general malfunction with Pressure Control Solenoid K. This is a non-specific code indicating the solenoid is not functioning properly, which affects transmission hydraulic pressure control.
The most common cause of P2828 (Pressure Control Solenoid "K") is: Failed or worn pressure control solenoid K
Typical repair costs for P2828 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in transmission slipping, harsh shifts, or reduced performance. Continued operation could lead to transmission damage and unexpected vehicle behavior.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2828 to identify the root cause.
