B0001 - PCM Discrete Input Speed Signal Error
B0001 is a code that tells you there is something wrong with the speed signal. The speed signal is used by the computer in your car (PCM) to know how fast your car is going and other important things.
The speed signal can come from different places, such as the vehicle speed sensor, wheel speed sensors, and the ABS module. The PCM checks the speed signal and compares it to other sensors to know the speed and other important things.
If the PCM finds a problem with the speed signal, it will set B0001. This code can be because of:
- A bad vehicle speed sensor
- A bad wheel speed sensor
- A bad ABS module
- A problem with the wires or connectors for the vehicle speed sensor, wheel speed sensor, or ABS module
- A problem with the PCM
Some signs that you have B0001 are:
- Your check engine light is on
- Your speedometer does not work
- Your cruise control does not work
- Your transmission shifts badly
- Your engine runs poorly
To fix B0001, you need to do these steps:
- Check the vehicle speed sensor and wheel speed sensors for any damage or wear. If they are bad, replace them.
- Check the voltage in the speed signal circuit. If the voltage is too low, there may be a broken wire or connector in the wires.
- Check the PCM for any damage or corrosion. If it is bad, replace it.
The cost to fix B0001 depends on what is causing it. If the vehicle speed sensor or wheel speed sensor is bad, it may cost around $100-$200 to replace it. If the ABS module is bad, it may cost around $300-$500 to replace it. If there is a problem with the wires or connectors, it may cost around $50-$100 to fix it. If the PCM is bad, it may cost around $500-$1000 to replace it.
Unfortunately you cannot prevent B0001, but you can help your vehicle speed sensor, wheel speed sensors, and ABS module last longer by keeping your engine oil clean and at the right level.
B0001 is a code that means there is a problem with the speed signal. This can cause your car to run badly and use more gas. If you have this code, you should have your car checked by a mechanic.
