P2719: Pressure Control Solenoid 'D' Control Circuit Range/Performance
The P2719 code indicates that the Powertrain Control Module (PCM) has detected a range or performance issue in the control circuit of pressure control solenoid 'D'. This solenoid regulates hydraulic pressure to the transmission clutches and bands for proper shifting. The PCM monitors the solenoid's electrical feedback; if the actual pressure or current deviates from the commanded value, this code sets. Common causes include faulty solenoid, wiring issues, low transmission fluid, or internal transmission problems.
1. Most Common Causes
- Faulty pressure control solenoid 'D'
- Wiring or connector issues in the solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping or stuck in gear
- Reduced fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top up or replace if necessary.
Step 3: Visually check wiring and connectors to the pressure control solenoid for damage or corrosion.
Step 4: Test solenoid resistance and compare to manufacturer specs; replace if out of range.
Step 5: Perform a pressure test or use a scan tool to monitor solenoid command and feedback.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause further transmission damage. Limited driving to a repair shop is acceptable if shifting is still possible.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, including parts and labor. Solenoid replacement is often $150-$300, plus diagnostic fees.
5. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
