Vehicle brakes lock up and can’t accelerate. I’m not sure exactly what part I need nor what needs to be fixed. The code says primary pressure sensor, would that be the part I need to fix vehicle.

the braking issue may be a separate issue, when the brake are locked up can you raise the front and then the rear of the car to see if the wheel spin? This guide can help

If any wheels are locked up please start a new thread. Can you double check the code number, there is no fuel pump module on this car.
