In order to change gears, an automatic transmission relies on little electromechanical devices known as pressure control solenoid’s to maintain the hydraulic pressure needed to change gears. If one of them gets stuck in the on position, the ECU will save a P2715 DTC.
How Serious is the Code?
At first, a P2715 diagnostic trouble code may not exhibit any noticeable transmission problems. However, the number of drivability problems can occur including, slipping, delayed shifts, engine stalling and transmission overheating.
Symptoms of a P2715 include:
- Erratic, delayed or harsh shifts
- Transmission slipping
- Engine stalls when braking
- Transmission gets stuck in a gear
- Vehicle won’t move when in gear
- Transmission overheats
- Limp mode
- Not enough transmission fluid
- Dirty transmission fluid / filter
- Damaged wiring/connector
- Malfunctioning pressure control solenoid
- Defective transmission pump
- Blocked pressure passage
- Valve body issue
- TCM or ECU failure
How to Diagnose the Code?
Since a P2715 OBDII diagnostic trouble code refers to the pressure control solenoid, the first thing that should be considered is the level and condition of the transmission fluid. If it looks clean and bright, then the wiring and connectors on the transmission wiring harness should be evaluated for signs of damage or corrosion. If no issues are found, then the pressure control solenoid, valve body, transmission pump should be evaluated.
What Repairs Will Fix P2715?
- Changing the fluid and filter
- Replace faulty pressure control solenoid
- Repair or replace a faulty transmission pump
- Repair or replace defective transmission valve body
- Transmission flush to clean passages
- Cleaning corrosion from connectors
- Repairing or replacing wiring
- Flashing or replacing PCM
