Pressure Control Solenoid "G"
P2807 indicates the transmission control module detected a malfunction in Pressure Control Solenoid G, which regulates hydraulic pressure for transmission shifting and clutch engagement. This code means the solenoid is not operating within expected parameters, preventing proper transmission function.
What You Might Notice
- Check Engine Light illuminated
- Vehicle enters limp mode or reduced power mode
- Transmission slips or hesitates during gear shifts
- Transmission overheating
- Decreased fuel economy
Most Common Causes
- 1
Defective Pressure Control Solenoid G
The solenoid coil may be burned out, stuck, or electrically open, preventing proper valve actuation and pressure control.
- 2
Dirty or contaminated transmission fluid
Degraded fluid can cause solenoid sticking and prevent proper hydraulic pressure regulation throughout the transmission system.
- 3
Clogged transmission filter or restricted passages
Debris buildup reduces hydraulic flow and pressure, causing the control module to detect solenoid malfunction.
- 4
Corroded connector or faulty wiring
Damaged electrical connections or broken wires prevent proper solenoid control signals from the transmission control module.
How to Diagnose It
- 1
Check Defective Pressure Control Solenoid G — The solenoid coil may be burned out, stuck, or electrically open, preventing proper valve actuation and pressure control.
- 2
Check Dirty or contaminated transmission fluid — Degraded fluid can cause solenoid sticking and prevent proper hydraulic pressure regulation throughout the transmission system.
- 3
Check Clogged transmission filter or restricted passages — Debris buildup reduces hydraulic flow and pressure, causing the control module to detect solenoid malfunction.
- 4
Check Corroded connector or faulty wiring — Damaged electrical connections or broken wires prevent proper solenoid control signals from the transmission control module.
How to Fix It
- 1
Replace Pressure Control Solenoid G
Remove and install a new pressure control solenoid G assembly after confirming it is the faulty component through electrical testing.
- 2
Perform transmission fluid and filter service
Drain contaminated fluid, replace transmission filter, and refill with manufacturer-specified new transmission fluid to restore proper hydraulic function.
- 3
Inspect and repair solenoid connectors and wiring
Check connector pins for corrosion, clean contacts, and repair or replace any damaged wiring harnesses connected to Pressure Control Solenoid G.
- 4
Flush transmission hydraulic system
If restricted passages are suspected, perform a complete transmission fluid flush to clear blockages and restore full hydraulic pressure availability.
