Pressure Control Solenoid 'D' Control Circuit/Open
The P282D code indicates that the Powertrain Control Module (PCM) has detected an open or malfunction in the control circuit of the pressure control solenoid 'D'. This solenoid regulates hydraulic pressure to the transmission clutches and bands for proper shifting. An open circuit means there is a break in the electrical path, preventing the solenoid from operating correctly, which can lead to harsh or erratic shifting, slipping, or transmission damage.
1. Most Common Causes
- Faulty pressure control solenoid 'K' (open coil)
- Damaged, corroded, or disconnected wiring or connectors in the solenoid 'K' circuit
- Internal failure of the valve body
- Faulty transmission control module (TCM) or PCM (open internal driver)
- Low transmission fluid level or severe contamination affecting circuit impedance
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: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test solenoid resistance with a multimeter (compare to specs).
Step 4: Check for power and ground at the solenoid connector with key on.
Step 5: If wiring and solenoid are good, test PCM output or replace PCM.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with an open solenoid circuit can cause erratic shifting, transmission slippage, and potential internal damage. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, depending on whether the solenoid, wiring, or PCM needs replacement. Labor and parts vary by vehicle.
