P2722: Pressure Control Solenoid 'E' Electrical / Stuck Off
The P2722 code indicates a problem with the pressure control solenoid 'E', which is part of the transmission's hydraulic control system. This solenoid regulates fluid pressure to engage clutches and bands for proper gear shifting. The code sets when the Powertrain Control Module (PCM) detects an electrical malfunction (e.g., open or short circuit) or a mechanical issue (solenoid stuck off) in solenoid 'E'. This can cause harsh or delayed shifts, slipping, or limp mode.
1. Most Common Causes
- Faulty or internally shorted pressure control solenoid 'E'
- Open or shorted wiring in the solenoid circuit
- Corroded, bent, or loose pins/connectors at the transmission harness
- Low transmission fluid level or contaminated/ degraded fluid
- Mechanical blockage or debris in the valve body preventing solenoid movement
- Faulty transmission control module (TCM) or engine control module (ECM)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- Transmission stuck in limp mode (e.g., 2nd gear only)
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually inspect wiring and connectors to solenoid 'E' for damage or corrosion.
Step 4: Test solenoid resistance with a multimeter (specs vary by vehicle; typically 4-6 ohms).
Step 5: Perform a solenoid actuation test using a scan tool to verify operation.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with P2722 can cause further transmission damage due to improper shifting or slipping. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs vary: solenoid replacement typically $200-$500 including parts and labor; if internal damage is found, a rebuild or replacement can cost $1,500-$4,000.
