C0046

Right Front Wheel Speed Sensor Circuit Intermittent

Moderate severity

What it means

Intermittent open or short on the right front wheel speed sensor circuit. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.

Is it safe to drive?

Use caution

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
