What Does P2807 Mean?
The PCM has detected a general malfunction with pressure control solenoid 'G' in the transmission. This solenoid regulates hydraulic pressure for specific transmission functions and is not operating within expected parameters.
Common Causes
40%
Failed pressure control solenoid G
25%
Wiring harness or connector damage to solenoid G circuit
20%
Low or contaminated transmission fluid affecting solenoid operation
10%
Internal transmission valve body blockage or wear
5%
PCM internal driver circuit failure
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition; service if low, burnt, or contaminated
2
Step 2: Inspect solenoid connector and wiring for damage, corrosion, or oil intrusion
3
Step 3: Measure solenoid resistance and compare to manufacturer specifications
4
Step 4: Perform solenoid activation test using scan tool bidirectional controls and monitor pressure response
5
Step 5: If solenoid tests good externally, remove valve body to inspect solenoid, screens, and internal passages for debris or damage
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The PCM has detected a general malfunction with pressure control solenoid 'G' in the transmission. This solenoid regulates hydraulic pressure for specific transmission functions and is not operating within expected parameters.
The most common cause of P2807 (Pressure Control Solenoid "G") is: Failed pressure control solenoid G
Typical repair costs for P2807 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause harsh shifting, transmission slipping, or failure to engage certain gears. Continued operation may cause internal transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2807 to identify the root cause.
