This summary uses the existing diagnostic information shown in full below.
Your car's computer is having trouble talking to a part that tells it what gear the car is in. It's like when a walkie-talkie has a bad connection.
This code indicates that the transmission range sensor, which helps the car determine the correct gear, is sending a low voltage signal to the car's computer.
The transmission range sensor B circuit is responsible for providing the transmission control module (TCM) with the current gear position. A 'low' signal indicates that the voltage level is below the expected range, which could be due to wiring issues, sensor failure, or connector problems.
• Check Engine Light is on
• Transmission may not shift properly
• Vehicle may not start
• Faulty transmission range sensor
• Wiring issues or poor connections
• Faulty transmission control module (TCM)
Transmission Range Sensor: A sensor that detects the position of the gear selector.
TCM: Transmission Control Module, the computer that manages transmission functions.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for damage or corrosion
• Test the transmission range sensor for proper operation
• Replace the transmission range sensor if faulty
• Repair or replace damaged wiring or connectors
• Replace the TCM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Focus
• Toyota Camry
• Honda Accord
• Regularly inspect and maintain transmission components
• Ensure wiring and connectors are secure and free from corrosion
• Use the correct transmission fluid and change it as recommended
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with your vehicle manufacturer as transmission components may be covered under powertrain warranty.
This code has been associated with transmission issues in vehicles with electronic shift controls.
Moderate – It is advisable to address this issue soon to prevent potential transmission damage.
Ignoring this code can lead to unsafe driving conditions and potential legal issues if the vehicle becomes inoperable.
• Vehicle in park or neutral
• Engine running at idle
The transmission range sensor is typically located on the transmission housing.
Q: Can I drive with a P2802 code?
A: It's not recommended as it can lead to further transmission damage.
Q: How do I reset the P2802 code?
A: After repairs, use an OBD-II scanner to clear the code.
