• Solutions

The P2718 fault code indicates an issue with the "Pressure Control Solenoid D Control Circuit," which may be internal to the transmission. This code is common in automated transmission systems where solenoids are used to control fluid pressure for various functions, affecting the overall operation of the transmission.

What are the symptoms of the P2718 code?

Symptoms associated with this fault code may include:

• Erratic shifting or harsh transmission behavior
• Slipping of the transmission
• Illuminated check engine light on the dashboard
• Decreased fuel efficiency
• Possible overheating of the transmission.

What causes the P2718 code?

Possible causes of this code could include:

• A faulty pressure control solenoid D
• Open or shorted wiring in the control circuit
• Faulty transmission control module (TCM)
• Low transmission fluid levels or poor fluid condition
• A direct issue within the transmission itself such as a mechanical failure.

How to fix P2718?

To resolve the P2718 code, follow these steps:

1. Inspect the wiring and connectors for any signs of damage, corrosion, or loose connections.
2. Check the transmission fluid levels and condition; replace fluid if necessary.
3. Test the pressure control solenoid D for proper operation and replace if it is faulty.
4. If the solenoid is functioning, consider testing the TCM for faults.
5. Clear the fault code and conduct a test drive to ensure the issue is resolved.
