Wheel Speed Sensor Circuit - Range/Performance Problem
This code indicates a problem with the wheel speed sensor reading.
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 wheel speed sensor tells the computer how fast each wheel is spinning. If the sensor fails or the signal is messed up, the computer won't get the right speeds and throws this code.
What the computer is actually seeing
The computer expects the wheel speed sensor to output a voltage signal that changes with wheel speed, typically between 0.5V to 3.5V at normal driving speeds. If the signal is too low or too high consistently, it sets the code.
What a healthy reading looks like
Voltage output from the sensor should vary with speed: 0.5V at rest, up to 3.5V at full speed. Resistance of the sensor should be between 1,000 and 1,500 ohms when measured with a multimeter.
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 for any obvious wiring issues or connector damage related to the wheel speed sensor; fix any that are found. Decision: If wiring is okay, proceed to step 2.
- 2Use a multimeter to measure the resistance of the wheel speed sensor; it should be between 1,000 and 1,500 ohms. Decision: If resistance is out of spec, replace the sensor. If okay, proceed to step 3.
- 3Check the voltage output from the sensor while the vehicle is moving; it should vary from 0.5V at rest to 3.5V at high speeds. Decision: If the signal is flat or out of range, replace the sensor. If the signal is good, check further down the circuit.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors to the sensor
- Corrosion in the connection points
- Absence of proper signal ground for the sensor

Frequently asked questions
Is it safe to drive with this code?
It’s moderate severity; you can drive but fix it soon to ensure proper traction control and ABS functions.
Will this code come back after clearing?
If the issue is fixed, it shouldn't return. If it does, there may be an underlying problem.
Why is this code set when the car drives fine?
Sometimes the sensor signal can be erratic, causing the computer to throw this code even if the car seems to drive normally.
