• Solutions

The P2717 fault code indicates an issue with the Pressure Control Solenoid D in the transmission system. This solenoid plays a crucial role in regulating hydraulic pressure within the transmission, which affects shift timing and overall vehicle performance. When the solenoid is intermittent, it can lead to unpredictable shifting and reduced drivability in your vehicle.

What are the symptoms of the P2717 code?

Drivers may experience a variety of symptoms when the P2717 code is triggered, such as:

• Slipping or delayed shifting when changing gears
• Harsh or erratic shifting behavior
• Warning lights on the dashboard, particularly the Check Engine Light
• Decreased fuel efficiency due to unregulated power delivery
• Possible overheating of the transmission due to improper fluid pressure

What causes the P2717 code?

Several factors can lead to the P2717 code, including:

• A faulty Pressure Control Solenoid D, which may be failing to operate consistently
• Wiring issues, such as frayed or shorted wires that affect the solenoid's operation
• Poor electrical connections or corroded terminals that lead to intermittent signals
• A malfunctioning transmission control module (TCM) that misinterprets input signals
• Contaminated transmission fluid, which can inhibit solenoid performance

How to fix P2717?

To resolve the P2717 fault code, you may take the following steps:

• Begin by inspecting the wiring and connectors for the Pressure Control Solenoid D, ensuring there are no visible damages. Repair or replace any faulty wiring.
• Check the solenoid itself for proper operation; replacing it may be necessary if it’s found to be faulty.
• Ensure the transmission fluid is clean and at the correct level; replace it if contaminated.
• Update the transmission control module software if applicable, and in some cases, replacing the TCM may resolve the issue.
• Utilize professional diagnostic tools to clear the code and monitor for any reoccurrence after repairs.
