Pressure Control Solenoid "E" Performance/Stuck Off
The transmission control module has detected a performance problem or stuck condition with Solenoid E, which is a pressure control solenoid that regulates transmission fluid pressure. This solenoid failure prevents proper hydraulic pressure management, causing shifting issues and potential transmission damage if not addressed.
What You Might Notice
- Check Engine Light illuminated
- Transmission enters limp mode (reduced power/fixed gear)
- Transmission slips during gear changes
- Transmission overheating
- Decreased fuel economy
- Hard or delayed shifting engagement
Most Common Causes
- 1
Defective Pressure Control Solenoid E
The solenoid coil has failed electrically or the valve is mechanically stuck. This prevents proper modulation of transmission fluid pressure needed for smooth shifts.
- 2
Dirty or Contaminated Transmission Fluid
Degraded fluid or debris buildup clogs the solenoid passages or prevents the valve from moving freely, causing performance degradation.
- 3
Faulty Solenoid Wiring or Connector
Corroded, damaged, or loose electrical connections prevent proper signal delivery to the solenoid, causing it to malfunction or not respond.
- 4
Clogged Transmission Filter or Restricted Passages
A dirty filter or restricted hydraulic passages reduce fluid flow to the solenoid and throughout the transmission system, affecting pressure regulation.
How to Diagnose It
- 1
Check Defective Pressure Control Solenoid E — The solenoid coil has failed electrically or the valve is mechanically stuck. This prevents proper modulation of transmission fluid pressure needed for smooth shifts.
- 2
Check Dirty or Contaminated Transmission Fluid — Degraded fluid or debris buildup clogs the solenoid passages or prevents the valve from moving freely, causing performance degradation.
- 3
Check Faulty Solenoid Wiring or Connector — Corroded, damaged, or loose electrical connections prevent proper signal delivery to the solenoid, causing it to malfunction or not respond.
- 4
Check Clogged Transmission Filter or Restricted Passages — A dirty filter or restricted hydraulic passages reduce fluid flow to the solenoid and throughout the transmission system, affecting pressure regulation.
How to Fix It
- 1
Replace Pressure Control Solenoid E
Remove the old solenoid from the transmission valve body or housing and install a new or remanufactured unit. Torque to manufacturer specifications and ensure proper seating.
- 2
Perform Transmission Fluid and Filter Service
Drain old fluid, replace the transmission filter, and refill with clean fluid of the correct type and capacity. This removes contamination that may have damaged the solenoid.
- 3
Inspect and Repair Solenoid Wiring and Connector
Check the solenoid connector and wiring harness for corrosion, damage, or loose connections. Clean corrosion, repair damaged wires, or replace the connector as needed.

Have Transmission Scanned and Relearn Performed
After repairs, use a transmission-capable diagnostic scanner to clear the code and perform any required system resets or adaptive relearns to ensure proper solenoid operation.
