Laymans terms

This code means that the car's computer has detected a problem with the electrical circuit that controls the part of the transmission that selects gears.

Explanation

The P0913 code is triggered when the transmission control module (TCM) detects a high voltage condition in the gate select actuator circuit.

Technical description

The gate select actuator is responsible for selecting the appropriate gear in a vehicle's transmission. The circuit high condition indicates that there is an abnormally high voltage reading in the actuator circuit, which could be due to a short circuit, a faulty actuator, or wiring issues.

Symptoms

• Check Engine Light illuminated

• Transmission may not shift properly

• Vehicle may not go into gear

Common Causes

• Faulty gate select actuator

• Wiring issues such as a short circuit or open circuit

• Faulty transmission control module (TCM)

Glossary

Actuator: A device that moves or controls a mechanism or system.

Diagnosis steps

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

• Inspect the wiring and connectors related to the gate select actuator for damage.

• Test the gate select actuator for proper operation.

Repair procedures

• Repair or replace damaged wiring or connectors.

• Replace the faulty gate select actuator.

• Reprogram or replace the transmission control module if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools
