P2813 - Pressure Control Solenoid Control Circuit Range/Performance
The P2813 code indicates that the Transmission Control Module (TCM) has detected a range or performance issue in the control circuit of the pressure control solenoid. This solenoid regulates hydraulic pressure within the transmission to control shift timing and firmness. A malfunction can cause erratic shifting, slipping, or harsh engagement.
1. Most Common Causes
- Faulty pressure control solenoid
- Wiring or connector issues in the solenoid circuit
- Low transmission fluid level or dirty fluid
- Internal transmission mechanical failure
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifts
- Transmission slipping
- Poor 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.
Step 3: Visually check wiring and connectors for damage or corrosion.
Step 4: Test solenoid resistance and supply voltage with a multimeter.
Step 5: Perform a transmission pressure test to confirm solenoid operation.
4. Frequently Asked Questions
