Technical Description of OBD-II Trouble Code
The Pressure Control Solenoid D is stuck in the “On” position.
What does that mean?
This is a generic diagnostic trouble code (DTC) for transmission issues 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 P2715 OBD-II trouble code is triggered, it means that the Powertrain Control Module (PCM) has detected 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 code determines which code is set and causes the Check Engine Light to illuminate.
The Transmission Pressure Control Solenoids are responsible for regulating the fluid pressure in an automatic transmission to ensure proper operation. The PCM receives electronic signals from these solenoids based on the pressure within them. The transmission’s bands and clutches rely on the right fluid pressure at the right time to change gears. By monitoring the vehicle’s speed, the PCM controls the pressure solenoids to direct fluid at the correct pressure to different hydraulic circuits, allowing the transmission to shift gears at the appropriate time.
The P2715 code indicates that the Pressure Control Solenoid “D” is stuck in the “On” position.

What are some P2715 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. Additionally, checking the vehicle records for the last fluid and filter change is advisable.
Fluid & Wiring Inspections
Start by checking the fluid level and examining its condition for any contamination. Before changing the fluid, verify the last time the filter and fluid were changed using the vehicle records.
Next, perform a detailed visual inspection of the wiring for 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 diagnosis. These procedures involve using a digital multimeter and referencing the specific technical guidelines for the vehicle. Voltage and fluid pressure requirements may vary depending on the vehicle’s model and transmission design.
Continuity Checks
Unless specified otherwise in the technical data, the normal readings for wiring and connections should show 0 ohms of resistance. Continuity checks should always be performed with the power removed from the circuit to avoid shorting the circuit and causing further damage. Resistance or lack of continuity indicates faulty wiring that needs to be repaired or replaced.
