What Does P2811 Mean?
The TCM has detected an intermittent fault in pressure control solenoid 'G'. This indicates the solenoid or its circuit is experiencing sporadic failures that come and go, making diagnosis more challenging.
Common Causes
40%
Intermittent wiring connection or corroded connector pins causing sporadic contact
30%
Solenoid 'G' beginning to fail with intermittent internal shorts or opens
15%
Low or contaminated transmission fluid causing intermittent solenoid sticking
10%
Loose or damaged ground connection in transmission circuit
5%
Intermittent TCM internal fault
Diagnostic Steps
1
Step 1: Perform wiggle test on all transmission harness connectors while monitoring live data for fault occurrence
2
Step 2: Inspect connector pins for corrosion, bent pins, or backed-out terminals; clean and repair as needed
3
Step 3: Check all transmission ground connections for tightness and corrosion
4
Step 4: Monitor solenoid resistance and voltage during driving conditions when fault typically occurs
5
Step 5: Use thermal imaging or heat gun to test for temperature-related intermittent failures in solenoid or wiring
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
The TCM has detected an intermittent fault in pressure control solenoid 'G'. This indicates the solenoid or its circuit is experiencing sporadic failures that come and go, making diagnosis more challenging.
The most common cause of P2811 (Pressure Control Solenoid "G" Intermittent) is: Intermittent wiring connection or corroded connector pins causing sporadic contact
Typical repair costs for P2811 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience unpredictable shifting behavior or sudden loss of certain gears. Intermittent nature makes failure unpredictable during operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2811 to identify the root cause.
