Hello. P0001 is a code for a problem with the fuel volume regulator circuit.

The fuel volume regulator is the component responsible for regulating the amount of fuel that is consumed by the engine. If the regulator has a problem, this can cause the engine to have problems with too little or too much fuel, which may reduce it's power output and performance.

I would recommend having the fuel regulator and wiring checked to make sure that they are in good condition and functioning properly. I would also check the transmission fluid level, just to be sure that it is not low, as that can also produce the symptoms you are experiencing. If you want to have a certified technician inspect your shifting issue, a certified technician from YourMechanic can come to your home or office to conduct diagnostics on your vehicle.
