P0913
UniversalGate Select Actuator Circuit High
Medium SeverityThe Gate Select Actuator circuit is reporting an abnormally high voltage to the vehicle's computer. This usually indicates an electrical problem within the circuit controlling the gear selector mechanism, which can prevent proper gear selection.
⚠️ Before You Begin (Safety First)
Always disconnect the battery before performing any electrical work. Be cautious when working around moving parts or hot engine components. Ensure the vehicle is securely supported if raised.
Common Symptoms
- Check Engine Light (MIL) illuminated
- Difficulty shifting gears
- Transmission stuck in a single gear
- Inability to select gears (e.g., cannot shift out of Park or into Drive)
- Erratic gear selection or unexpected shifts
- Transmission warning light illuminated
Common Causes
- Faulty Gate Select Actuator
- Short to voltage in the Gate Select Actuator circuit
- Corroded or loose electrical connectors for the actuator
- Damaged or frayed wiring in the actuator circuit
- Faulty Transmission Control Module (TCM) or Powertrain Control Module (PCM) (less common)

Diagnostic Steps
- Visually inspect the wiring harness and connectors leading to the Gate Select Actuator for any signs of damage, corrosion, or looseness.
- Check for any obvious shorts to voltage on the circuit using a multimeter.
- If accessible, test the resistance and voltage at the actuator connector according to the vehicle's service manual specifications.
- If the actuator is externally accessible, check its operation, if possible, or test its internal resistance.
- Clear the code and retest the vehicle to see if the code returns.
👨🔧 When to Call a Professional
If you have checked basic wiring and connectors and the issue persists, or if you suspect internal transmission issues, it's best to consult a professional for advanced diagnostics.
Commonly Asked Questions
What is a Gate Select Actuator?
It's a component that mechanically moves the shift lever or internal transmission components to select different gear gates (like Park, Reverse, Neutral, Drive) in vehicles with electronic shifting or automated manual transmissions.
Can I drive with a P0913 code?
Driving with a P0913 code is not recommended, as it can lead to unpredictable gear shifts or an inability to select gears, which can be dangerous.
Is this a difficult repair for a DIYer?
It can range from medium to advanced. Basic electrical checks are doable, but diagnosing an intermittent short or replacing the actuator itself might require specific tools or knowledge.
Could a low battery cause this code?
While a severely low battery can cause various electrical gremlins, it's less likely to directly cause a 'circuit high' error in a specific actuator circuit unless it impacts the control module's ability to regulate voltage correctly.
What's the difference between this and a transmission internal fault?
This code specifically points to an electrical issue with the mechanism that selects the gear gate, not necessarily a mechanical problem with the gears themselves within the transmission.
