Wheel Speed Sensor 3 Input Circuit Failure
There's a problem with the input from Wheel Speed Sensor 3.
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 a proper signal from the third wheel speed sensor, which helps control things like ABS and traction control. This can happen if the sensor is damaged or the wiring to it is broken.
What the computer is actually seeing
The control module expects a variable voltage signal from the wheel speed sensor between 0.5V to 5V, reflecting the wheel's rotation speed. If it sees no signal or a constant signal outside this range, it triggers a fault code.
What a healthy reading looks like
Expected voltage from the wheel speed sensor should range from 0.5V at rest to approximately 5V as wheel speed increases.
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 at Wheel Speed Sensor 3 for any visible damage or corrosion. Repair or clean as necessary and retest.
- 2Using a multimeter, measure the voltage at the wheel speed sensor connector while the vehicle is moving. Verify it matches expected values (0.5V to 5V). If not, continue to the next step.
- 3Inspect the ABS control module for fault codes or malfunctions. If it reports issues related to this sensor, further diagnose the module.
- 4If everything checks out, replace Wheel Speed Sensor 3 and check for any other related codes after installation.
Common causes
- Failed wheel speed sensor
- Damaged wiring or connectors
- Corrosion at the connector
- Faulty ABS control module
- Wheel bearing issues affecting sensor position

Frequently asked questions
Is it safe to drive with this code?
It's drivable but be aware that ABS and traction control may not function properly, which can affect safety.
Will this code come back if I clear it?
Yes, if the underlying fault isn't fixed, the code will return.
Why does this code pair with others like C1185?
These codes often indicate issues with different wheel speed sensors or the system's ability to interpret their signals.
