The P2814 fault code refers to an issue with the Pressure Control Solenoid G in the vehicle's transmission system. This solenoid is responsible for regulating fluid pressure within the transmission. When the control circuit detects a low voltage or resistance, it triggers this fault code, indicating that the solenoid may not be functioning properly. Addressing this issue is essential to ensure smooth shifting and optimal transmission performance.

What are the symptoms of the P2814 code?

Drivers may experience several symptoms when the P2814 error code is present, including:

• Harsh or erratic shifting of the transmission.
• Slipping gears or failure to shift into certain gears.
• Unusual noises coming from the transmission when shifting.
• Transmission overheating due to improper fluid pressure.

What causes the P2814 code?

Several factors can lead to the P2814 code being triggered, including:

• A faulty Pressure Control Solenoid G that is not adequately controlling hydraulic pressure.
• Electrical issues such as damaged wiring, corroded connectors, or bad grounds in the control circuit.
• Low transmission fluid levels or contamination in the fluid that may affect solenoid operation.
• A malfunctioning Transmission Control Module (TCM) that fails to send the correct signals to the solenoid.

How to fix P2814?

To resolve the P2814 fault code, consider the following steps:

• Inspect and repair any damaged wiring or connectors related to the Pressure Control Solenoid G.
• Replace the Pressure Control Solenoid G if it is found to be defective.
• Check and top off transmission fluid levels; ensure the fluid is clean and free from contaminants.
• Update or reprogram the Transmission Control Module if it is identified as the cause of signal issues.
• After repairs are made, clear any stored codes and conduct a road test to verify proper operation.
