This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's computer not being able to tell which direction the gear shifter is moved. It's like when you can't tell if a light switch is on or off.
The P2793 code is triggered when the powertrain control module (PCM) detects an issue with the gear shift direction circuit. This circuit helps the car understand if you want to go forward, backward, or stay in neutral.
The gear shift direction circuit is responsible for sending signals to the PCM about the current gear position. If the circuit is open, shorted, or otherwise malfunctioning, the PCM cannot accurately determine the gear position, leading to the P2793 code.
• Check Engine Light illuminated
• Transmission may not shift properly
• Vehicle may not move in the intended direction
• Faulty gear shift position sensor
• Damaged wiring or connectors in the gear shift circuit
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the gear shift position sensor and its wiring.
• Test the circuit for continuity and shorts.
• Replace the gear shift position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdrivers and wrenches

Moderate
• Toyota Camry
• Ford F-150
• Honda Accord
• Regularly inspect and maintain transmission components.
• Avoid harsh shifting and driving habits.
• Ensure proper electrical connections in the vehicle.
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on transmission components.
The P2793 code has been increasingly reported in vehicles with electronic gear shift systems as they become more common.
Moderate – While the vehicle may still be drivable, improper shifting can lead to unsafe driving conditions.
Driving with a malfunctioning transmission can be dangerous. Always ensure your vehicle is in proper working condition.
• Vehicle should be on a flat surface.
• Ensure the engine is at operating temperature.
The gear shift position sensor is usually located on the transmission or gear shift assembly.
Q: Can I drive with a P2793 code?
A: It's not recommended as it can lead to unsafe driving conditions.
Q: How do I reset the P2793 code?
A: After repairs, use an OBD-II scanner to clear the code.
