Technical Description of OBD-II Trouble Code
The Pressure Control Solenoid D is experiencing intermittent issues.
What does that mean?
This is a generic diagnostic trouble code (DTC) for transmission and is commonly found in OBD-II vehicles with automatic transmissions.
This can apply to various vehicle brands such as Toyota, Chevy, Chevrolet, Lexus, Nissan, GMC, Cadillac, Pontiac, Buick, Honda, Acura, Mercedes-Benz, VW, Audi, etc. However, the repair steps may vary depending on the year, make, model, and powertrain configuration.
When the P2717 OBD-II trouble code is detected, it means that the Powertrain Control Module (PCM) has identified a problem with the Transmission Pressure Control Solenoid “D”. Most automatic transmissions have three solenoids: A, B, and C. The trouble codes related to the “D” solenoid are P2713, P2714, P2715, P2716, and P2717. The specific malfunction that triggers the PCM and illuminates the Check Engine Light determines the code set.
The Transmission Pressure Control Solenoids are responsible for regulating the fluid pressure for proper automatic transmission operation. The PCM receives an electronic signal based on the pressure within the solenoids. The transmission’s bands and clutches change gears by having fluid pressure in the correct location at the appropriate time. Based on signals from devices that monitor the vehicle’s speed, the PCM controls the pressure solenoids to direct fluid at the right pressure to hydraulic circuits that change the transmission gear ratio at the correct timing.
The P2717 code is set when the Pressure Control Solenoid “D” operates intermittently.

What are some P2717 troubleshooting steps?
Prior to troubleshooting, it is recommended to research the Technical Service Bulletins (TSB’s) specific to the vehicle’s year, model, and transmission. This can save time by providing guidance in the right direction. It is also advisable to check the vehicle records to determine the last time the filter and fluid were changed, if possible.
Fluid & Wiring Inspections
Begin by checking the fluid level and examining its condition for contamination. Before changing the fluid, verify the last time the filter and fluid were changed by referring to the vehicle records.
Next, conduct a detailed visual inspection of the wiring to identify any obvious defects. Check the connectors and connections for security, corrosion, and damaged pins. This includes all wiring and connectors related to the transmission pressure control solenoids, transmission pump, and PCM. Depending on the configuration, the transmission pump may be electrically or mechanically driven.
Advanced Steps
The advanced steps are highly vehicle-specific and require specialized equipment for accurate execution. These procedures necessitate a digital multimeter and the specific technical references for the vehicle. Obtain the specific troubleshooting guidelines for the vehicle before proceeding with the advanced steps. Voltage and fluid pressure requirements may vary based on the vehicle’s model and transmission design.
Continuity Checks
Unless otherwise specified by the technical data, the normal readings for wiring and connections should be 0 ohms of resistance. Continuity checks should always be performed with the power removed from the circuit to prevent shorting the circuit and causing further damage. Resistance or lack of continuity indicates faulty wiring that is either open or shorted and requires repair or replacement.
