What Does P2808 Mean?
Pressure control solenoid 'G' is either stuck in the off position or not responding properly to PCM commands. The solenoid is failing to modulate hydraulic pressure as required for proper transmission operation.
Common Causes
45%
Mechanically stuck or failed pressure control solenoid G
25%
Debris or varnish buildup in solenoid valve preventing movement
15%
Open circuit in solenoid wiring or connector
10%
Contaminated transmission fluid causing solenoid sticking
5%
Internal valve body damage or blocked passages
Diagnostic Steps
1
Step 1: Verify transmission fluid level and condition; note any burnt smell or debris
2
Step 2: Test solenoid resistance with multimeter; should be within manufacturer specifications (typically 4-25 ohms)
3
Step 3: Check for voltage supply and ground at solenoid connector with key on
4
Step 4: Command solenoid on/off with scan tool and listen/feel for clicking or use pressure gauge to verify operation
5
Step 5: Remove solenoid from valve body, inspect for physical damage or contamination, and test operation off-vehicle
Estimated Repair Cost
$250 - $1,400
Parts + labor, varies by vehicle and location
Pressure control solenoid 'G' is either stuck in the off position or not responding properly to PCM commands. The solenoid is failing to modulate hydraulic pressure as required for proper transmission operation.
The most common cause of P2808 (Pressure Control Solenoid "G" Performance/Stuck Off) is: Mechanically stuck or failed pressure control solenoid G
Typical repair costs for P2808 range from $250 to $1,400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission may exhibit harsh shifts, delayed engagement, or stay in limp mode. Continued driving may cause additional transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2808 to identify the root cause.
