What Does P282A Mean?
The transmission control module has detected that Pressure Control Solenoid K is stuck in the on position. This causes continuous hydraulic pressure application when the solenoid should be off, disrupting normal transmission operation.
Common Causes
40%
Mechanically stuck pressure control solenoid K in energized position
25%
Contaminated solenoid valve preventing return spring operation
20%
Short to power in solenoid K control circuit wiring
10%
Valve body spool valve stuck due to varnish or debris
5%
Failed transmission control module with shorted output
Diagnostic Steps
1
Step 1: Command solenoid K off using scan tool and verify TCM is sending correct signal
2
Step 2: Measure voltage at solenoid K connector with command off; should show 0V
3
Step 3: Disconnect solenoid K and retest to determine if issue is electrical or mechanical
4
Step 4: Check for short to power in wiring harness between TCM and solenoid K
5
Step 5: Remove and bench test solenoid K for mechanical sticking or binding
Estimated Repair Cost
$250 - $1,400
Parts + labor, varies by vehicle and location
The transmission control module has detected that Pressure Control Solenoid K is stuck in the on position. This causes continuous hydraulic pressure application when the solenoid should be off, disrupting normal transmission operation.
The most common cause of P282A (Pressure Control Solenoid "K" Stuck On) is: Mechanically stuck pressure control solenoid K in energized position
Typical repair costs for P282A range from $250 to $1,400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause incorrect gear engagement, harsh shifts, or transmission overheating. Could result in sudden unexpected shifts affecting vehicle control.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P282A to identify the root cause.
