The car's computer is saying there's a problem with the front right wheel's speed sensor. It's like the sensor is shouting too loudly, and the computer can't understand what's going on.
The wheel speed sensor is sending a voltage signal that is higher than expected, which can be due to various electrical issues.
The C1205 code indicates that the wheel speed sensor for the front right wheel is reporting a voltage level that is too high. This may be due to a short circuit, faulty sensor, or issues with the wiring harness.

Moderate – This issue affects the ABS system, which is important for safe braking.
Driving with a malfunctioning ABS system can increase stopping distances and the risk of skidding.
• Vehicle parked on a level surface

The wheel speed sensor is located near the wheel hub of the front right wheel.
Q: Can I drive with a C1205 code?
A: It's possible to drive, but it's not safe as the ABS system may not function properly.
Q: How can I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
