Wheel Speed Sensor Malfunction
The system detects a problem with a wheel speed sensor.
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 monitors the speed of each wheel. If it detects a fault, like an open circuit or wrong voltage, it sends this signal to the computer.
What the computer is actually seeing
The computer is looking for valid signals from the wheel speed sensors, typically 0-5 volts. If it sees no signal or a signal that does not match expected patterns, it will trigger this code.
What a healthy reading looks like
0-5 volts for normal operation; should fluctuate based on wheel speed.
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 related to the wheel speed sensor for damage or corrosion. Decision: If damaged, repair or replace. If okay, move to step 2.
- 2Measure the voltage at the wheel speed sensor connector with key on (engine off). Expected voltage should be 0-5 volts. Decision: If outside this range, check power and ground supply. If okay, move to step 3.
- 3Check the resistance of the wheel speed sensor. It should be between 1,000 and 2,500 ohms. Decision: If resistance is out of spec, replace the sensor.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Low battery voltage
- ABS module issues
Typical repair cost
