Laymans terms

This code means that the computer in your car thinks there's a problem with one of the parts that helps control how smoothly the car changes gears. It's like a switch that isn't working right.

Explanation

The transmission control module (TCM) has detected a high voltage condition in the circuit controlling the pressure control solenoid 'E'.

Technical description

The pressure control solenoid 'E' is responsible for regulating hydraulic pressure in the transmission. A 'circuit high' condition indicates that the voltage in the solenoid's circuit is higher than expected, which can affect transmission performance.

Symptoms

• Harsh or erratic shifting

• Transmission slipping

• Check Engine Light illuminated

Common Causes

• Faulty pressure control solenoid 'E'

• Wiring issues such as shorts or open circuits

• Faulty transmission control module (TCM)

Glossary

Transmission Control Module (TCM): A computer that controls the transmission's operation.

Solenoid: An electromechanical device that controls the flow of fluid in the transmission.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for damage or corrosion.

• Test the pressure control solenoid 'E' for proper operation.

Repair procedures

• Repair or replace damaged wiring or connectors.

• Replace the faulty pressure control solenoid 'E'.

• Replace or reprogram the transmission control module (TCM) if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$150 - $500
