Wheel Speed Sensor Input Circuit Range/Performance Problem
The wheel speed sensor signal is out of the expected range.
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 uses signals from the wheel speed sensor to monitor how fast each wheel is turning. If one wheel's signal looks odd or unusual compared to the others, it triggers this code.
What the computer is actually seeing
The ECU expects a consistent signal from each wheel speed sensor, typically a square wave that switches between 0 and 5 volts. A range of 1 to 4 volts indicates issues in the signal consistency.
What a healthy reading looks like
Typically sees a frequency of around 1-10 Hz at low speeds, increasing with vehicle speed. Signal voltage should switch between 0-5 volts during operation.
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.
- 11. Check wheel speed sensor connectors for corrosion and secure fit.
- 22. Measure voltage at the wheel speed sensor connector with the ignition ON (should be approximately 5 volts). If not, repair the power circuit. Proceed to step 3 if voltage is good.
- 33. Inspect the wiring harness for any physical damage from the sensor to the ABS module. Look for shorts or opens. Repair as necessary.
- 44. Test the sensor output signal with a multimeter while spinning the wheel. Signal should fluctuate between 0-5 volts. If no change, the sensor is likely faulty. Replace the sensor as needed.
- 55. If the sensor and wiring check out, test the ABS module for fault codes and functionality.
Common causes
- Faulty wheel speed sensor
- Damaged wiring to wheel speed sensor
- Faulty ABS module
