I have a 03 Buick Century 3.1 trouble code P0502, what does this mean

That is a speed sensor "a" low input code. Sometimes the sensors are external and sometimes they are internal. I don't remember specifically for your vehicle.

I would suggest monitoring the sensor with a higher end scan tool capable of reading transmission data.

I’m happy to assist further over the phone at

P0502 is a Vehicle speed sensor issue:
P0502 Description The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.

- Speedometer may not work properly
- Transmission shifting problem Possible Causes - Vehicle speed sensor harness or connectors is open or shorted
- Vehicle speed sensor
- Combination meter
- Faulty ECM.

The Code you're referring to should be a "P0502." What the Code signifies is: "Vehicle speed sensor circuit, low input."
