P2722: Pressure Control Solenoid 'E' Stuck On
The P2722 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the pressure control solenoid 'E' circuit, specifically that the solenoid is stuck in the 'on' position. This solenoid is part of the transmission's hydraulic control system, regulating fluid pressure to the clutches and bands for proper gear engagement. When stuck on, it can cause erratic shifting, harsh engagement, or transmission slippage, potentially leading to internal damage if not addressed.
01. Most Common Causes
- Faulty pressure control solenoid 'E'
- Wiring or connector issues in the solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Erratic or harsh shifting
- Transmission slipping or delayed engagement
- 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 for damage, corrosion, or loose connections.
Step 4: Test solenoid resistance and power/ground circuits with a multimeter.
Step 5: If solenoid is faulty, replace it; if wiring is bad, repair as needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may shift erratically or slip, potentially causing internal damage. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, including parts (solenoid) and labor. If internal transmission damage is found, costs can be higher.
