Pressure Control Solenoid 'G' Control Circuit Low
The P2826 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the control circuit of the pressure control solenoid 'G'. This solenoid is typically part of the transmission's hydraulic control system, regulating fluid pressure for clutch or band application. A low circuit condition can be caused by a short to ground, open circuit, or faulty solenoid, leading to improper transmission operation.
01. Most Common Causes
- Faulty pressure control solenoid 'G'
- Open or shorted wiring in the solenoid control circuit
- Poor electrical connection at the solenoid or PCM
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission shifting harsh or erratic
- Transmission slipping or stuck in gear
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data.
Step 2: Visually inspect wiring and connectors for damage, corrosion, or loose pins.
Step 3: Test solenoid resistance with a multimeter (compare to specs).
Step 4: Check for power and ground at the solenoid connector with key on.
Step 5: If wiring and solenoid are good, test PCM output or replace PCM.
