Gate Select Position Circuit A Range/Performance
This code means that the car's computer is having trouble figuring out what gear the car is in. It's like if your TV remote couldn't tell which channel you're trying to watch.
The P0905 code indicates a problem with the circuit that helps the car's computer know which gear is selected. This could be due to a range or performance issue within the circuit.
The P0905 code is triggered when the powertrain control module (PCM) detects a malfunction in the gate select position circuit 'A'. This circuit is responsible for communicating the current gear position to the vehicle's computer system. A range/performance issue suggests that the signal from this circuit is outside the expected range or is not performing as expected.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the gate select position sensor for proper operation.
• Replace the gate select position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect and maintain transmission components.
• Ensure wiring and connectors are free from corrosion.
• Keep software up to date with manufacturer updates.
Sensor Issue
• Avoid driving the vehicle if gear shifting becomes difficult.
• Consult a professional mechanic for accurate diagnostics.
Check with your vehicle manufacturer for warranty coverage on transmission components.
The P0905 code has been reported in vehicles with electronic transmission controls, particularly in models with high mileage.
Moderate – Should be addressed to prevent further transmission issues.
Driving with transmission issues can be unsafe and may lead to further mechanical damage.
• Vehicle should be at operating temperature.
• Test should be conducted while shifting through all gears.
The gate select position sensor is typically located on the transmission housing.
Q: Can I drive with a P0905 code?
A: It's not recommended to drive for long periods with this code, as it may lead to further transmission issues.
Q: How can I clear the P0905 code?
A: The code can be cleared with an OBD-II scanner, but the underlying issue should be fixed to prevent it from returning.
