Abs Wheel Speed Sensor 2 Circuit Failure
The control module has detected a fault in the circuit for wheel speed sensor 2.
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 car's computer isn't getting the right signals from the second wheel speed sensor, which helps control ABS and traction. This could be due to a damaged wire or a bad sensor.
What the computer is actually seeing
The computer expects consistent voltage readings from the sensor, usually around 0.5 to 4.5 volts, depending on speed. If it sees a fluctuating or missing signal, it triggers the C0114 code.
What a healthy reading looks like
A normal wheel speed sensor should output between 0.5V at a standstill to around 4.5V at speed. The signal should change as the wheel rotates.
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.
- 1Inspect wiring and connectors for damage or corrosion, particularly around wheel speed sensor 2.
- 2Check the resistance of the wheel speed sensor: should be between 1,000 and 5,000 ohms. Replace if out of range.
- 3Test the voltage output from the wheel speed sensor with a multimeter: should fluctuate between 0.5V and 4.5V with wheel rotation. If no output, replace the sensor.
- 4If the sensor and wiring are good, inspect the ABS control module for internal faults or issues.
Common causes
- Damaged wiring or connectors to the sensor
- Faulty wheel speed sensor 2
- Wheel bearing issues affecting the sensor
- Moisture or dirt in the connector
- Faulty ABS control module

Frequently asked questions
Is it safe to drive with this code active?
It's drivable, but you will lose ABS and traction control functions, increasing stopping distances on slippery surfaces.
Will the code come back if I clear it?
Yes, if the underlying issue isn't fixed, the code will most likely return.
Why does this code pair with others like C0110?
These codes often relate to issues with similar components or systems, such as multiple wheel speed sensors or faults in the ABS module.
