Wheel Speed Sensor Signal Intermittent
The wheel speed sensor signal is inconsistent.
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 expects a steady signal from the wheel speed sensor while driving, but it keeps getting interrupted, making it hard to track wheel speed accurately.
What the computer is actually seeing
The vehicle's control module expects a voltage signal from the wheel speed sensor between 0.5V (at rest) and 12V (moving), but sees fluctuations or losses in that signal.
What a healthy reading looks like
Signal from wheel speed sensor should be between 0.5V and 12V; must maintain a consistent reading under various speeds.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the wiring and connector for any visible damage or corrosion. Repair as necessary. Decision: Is the wiring okay? Yes: Go to step 2. No: Repair wiring.
Common causes
- Dirty or damaged wheel speed sensor
- Faulty sensor connector
- Broken or frayed wiring harness
- Wheel bearing issues affecting sensor location
- Faulty vehicle control module (rare)
Typical repair cost

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but you'll likely lose traction control and anti-lock braking functionality.
Will this code come back after I clear it?
If the underlying issue is not fixed, yes, it will likely return.
Why does this code sometimes pair with C1160?
C1160 indicates a general wheel speed sensor malfunction, while C1161 indicates intermittent signal issues.
