Pressure Control Solenoid 'E' Electrical Malfunction
The P2725 code indicates an electrical fault in the pressure control solenoid 'E', which is part of the transmission's hydraulic control system. This solenoid regulates fluid pressure to the clutch packs and bands, affecting shift quality and timing. The PCM detects an open or short circuit in the solenoid circuit, often due to wiring issues, connector corrosion, or internal solenoid failure.
01. Most Common Causes
- Faulty pressure control solenoid 'E'
- Open or shorted wiring in solenoid circuit
- Corroded or damaged connector
- Low transmission fluid level or contamination
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
- Transmission stuck in limp mode
03. 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 with a multimeter (specs vary by vehicle).
Step 5: Perform a solenoid actuation test using a scan tool.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a faulty pressure control solenoid can cause transmission damage, erratic shifting, or complete failure. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, including parts and labor. The solenoid itself is $50-$150, but labor can be higher if the transmission pan needs to be dropped.
