Pressure Control Solenoid Intermittent
The P2823 code indicates an intermittent fault in the pressure control solenoid circuit, which regulates hydraulic pressure within the automatic transmission. This solenoid is critical for proper shift timing and smooth gear changes. An intermittent signal suggests a loose connection, corroded wiring, or a failing solenoid that works sporadically, leading to unpredictable transmission behavior.
01. Most Common Causes
- Faulty pressure control solenoid
- Damaged wiring or connectors in the solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical issues
02. Symptoms You Will Notice
- Harsh or delayed gear shifts
- Transmission slipping or erratic shifting
- Check Engine Light illuminated
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off 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 power/ground circuits with a multimeter per manufacturer specs.
Step 5: If wiring is good, replace the pressure control solenoid.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as intermittent solenoid failure can cause sudden transmission issues, potentially leading to unsafe driving conditions or further transmission damage.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts (solenoid) and labor. Diagnostic fees may add $50-$100.
