P2714: Pressure Control Solenoid 'D' Performance/Stuck Off
The P2714 code indicates that the transmission control module (TCM) has detected a malfunction in the pressure control solenoid 'D', which is responsible for regulating hydraulic pressure within the transmission. The solenoid is commanded to a specific duty cycle, but the TCM does not see the expected pressure response, suggesting the solenoid is stuck in the off position. This can lead to harsh shifting, slipping, or loss of gear engagement.
1. Most Common Causes
- Low or contaminated transmission fluid (burnt or dirty)
- Faulty or mechanically stuck pressure control solenoid 'D'
- Electrical issues in the solenoid harness (short circuit, open circuit)
- Corroded, bent, or poorly connected transmission electrical connector
- Blocked or restricted hydraulic passages in the transmission valve body
- Internal transmission failure (burnt clutches or damaged oil pump)
- Faulty PCM (rare but possible)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifts
- Transmission slipping or overheating
- Reduced fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Inspect wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test solenoid resistance and operation using a multimeter or scan tool.
Step 5: If solenoid is faulty, replace it; if wiring is bad, repair or replace harness.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may slip or fail, causing unsafe driving conditions and potential damage.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, depending on whether the solenoid alone needs replacement or if additional transmission work is required.
