Pressure Control Solenoid "E" Control Circuit/Open
The transmission control solenoid E circuit is open or has lost electrical continuity, preventing proper pressure control in the automatic transmission. This causes the transmission to enter limp mode and may result in harsh shifting, slipping, or overheating.
What You Might Notice
- Check Engine Light illuminated
- Transmission enters limp mode with limited gear selection
- Hard or harsh gear shifts with banging sensation
- Transmission slipping between gears
- Increased fuel consumption and transmission overheating
Most Common Causes
- 1
Open or broken solenoid wiring
The electrical wire leading to solenoid E is broken, disconnected, or corroded, preventing current flow to the solenoid coil.
- 2
Failed pressure control solenoid E
The solenoid itself has failed internally with a broken coil or shorted windings, breaking the circuit path.
- 3
Corroded or damaged solenoid connector
The connector pins are corroded, bent, or the connector is loose, interrupting electrical contact between the wiring harness and solenoid.
- 4
Transmission control module malfunction
The PCM or transmission control module has a defect that prevents it from properly signaling solenoid E, though this is less common than wiring or solenoid failure.
How to Diagnose It
- 1
Check Open or broken solenoid wiring — The electrical wire leading to solenoid E is broken, disconnected, or corroded, preventing current flow to the solenoid coil.
- 2
Check Failed pressure control solenoid E — The solenoid itself has failed internally with a broken coil or shorted windings, breaking the circuit path.
- 3
Check Corroded or damaged solenoid connector — The connector pins are corroded, bent, or the connector is loose, interrupting electrical contact between the wiring harness and solenoid.
- 4
Check Transmission control module malfunction — The PCM or transmission control module has a defect that prevents it from properly signaling solenoid E, though this is less common than wiring or solenoid failure.
How to Fix It
- 1
Inspect and repair solenoid wiring
Check the wiring harness leading to solenoid E for breaks, cuts, or corrosion. Repair or replace damaged wires and reconnect any loose connectors, testing continuity with a multimeter.
- 2
Clean or replace solenoid connector
Disconnect the solenoid connector and inspect the pins for corrosion or damage. Clean with electrical contact cleaner or replace the connector assembly if damaged.
- 3
Replace pressure control solenoid E
If wiring and connectors are functional, the solenoid coil has likely failed internally. Remove and install a new pressure control solenoid E for the transmission.
- 4
Diagnose transmission control module
If solenoid and wiring are confirmed good, perform advanced diagnostics on the PCM or transmission control module using specialized diagnostic equipment to check circuit output.
