Wheel Speed Sensor 2 Circuit Failure
A problem with the wheel speed sensor 2 circuit has been detected.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer isn't getting the right signals from the wheel speed sensor 2, affecting ABS and traction control.
What the computer is actually seeing
The ABS control module expects to see a voltage signal from sensor 2, typically around 0.5V at rest and increases with wheel speed. If it reads below 0.1V for a prolonged period, it flags a problem.
What a healthy reading looks like
Voltage near 0.5V at rest, increasing to around 5V at maximum speed; should fluctuate with wheel movement.
