Wheel Speed Sensor Range/Performance Problem

The wheel speed sensor measures how fast each wheel is turning. If it sees values that are too low or inconsistent, it thinks there's an issue with the sensor or the wheels themselves.

The vehicle control module (VCM) receives signals from the wheel speed sensors. If it detects signals that are out of expected range—like very low voltage (below 0.5V) or erratic readings—it triggers the C1160 code.

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.

1. 11. Check wheel speed sensor wiring and connectors for physical damage or corrosion. Repair any issues found. Decision point: If repairs are made, clear the code and test drive. If code returns, proceed to step 2.
2. 22. Measure the voltage coming from the wheel speed sensor at rest. Expected should be around 0.5V to 2.5V. Decision point: If the voltage is out of range, replace the sensor. If it is within range, proceed to step 3.
3. 33. Inspect wheel bearings for excessive wear or play. Lift the vehicle, spin the wheels and listen for noises or roughness. Decision point: If bearings are worn, replace them. If they are good, proceed to step 4.
4. 44. Check if other wheel speed sensors show similar problems. Use a scan tool to view readings from all wheel speed sensors while driving. Decision point: If others are fine, replace the suspect sensor. If multiple sensors fail, check for a common ground issue.

• Faulty wheel speed sensor
• Damaged wiring or connectors
• Poor sensor ground
• Brake system irregularities
• Wheel bearing issues
