Transmission Control Module (TCM): The computer that controls the transmission's operation.

Related Codes

• P2814

• P2816

Official description

Pressure Control Solenoid G Control Circuit High

Laymans terms

Your car has a part that helps control the pressure in the transmission, like a faucet controlling water flow. This code means that the car's computer thinks the faucet is letting too much pressure through.

Explanation

The P2815 code indicates that the transmission control module has detected a high voltage condition in the pressure control solenoid G circuit.

Technical description

The pressure control solenoid G is responsible for regulating hydraulic pressure in the transmission. A high voltage condition in its control circuit suggests an electrical issue, possibly due to a short circuit or a faulty solenoid.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for damage or corrosion.

• Test the pressure control solenoid G for proper operation.

Repair procedures

• Repair or replace damaged wiring or connectors.

• Replace the faulty pressure control solenoid G.

• Reprogram or replace the transmission control module if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$200 - $500

Difficulty level

Moderate

Commonly affected vehicles

• Toyota Camry

• Honda Accord

• Ford Focus

Preventive measures

• Regular transmission fluid changes
