Wheel Speed Sensor 2 Circuit Range/Performance Problem
This code indicates an issue with the performance or range of the second 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 second wheel speed sensor is having problems reading the speed of the wheel accurately, which could be due to wiring issues or a faulty sensor.
What the computer is actually seeing
The ABS module monitors the voltage signal from the wheel speed sensor. It expects a specific voltage range that varies based on speed; if the voltage is too low or too high compared to the baseline reading, it triggers the C0732 code.
What a healthy reading looks like
The wheel speed sensor should send a signal voltage between 0.5V to 4.5V depending on the wheel speed; a steady voltage at rest should be around 0.5V to 1.5V.
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 the wiring and connectors for the second wheel speed sensor for damage and corrosion.
- 2Measure the voltage at the sensor connector: it should be within 0.5V to 4.5V while spinning the wheel. If it’s outside this range, replace the sensor.
- 3Inspect the wheel bearing and hub assembly for any mechanical issues that might affect the sensor reading.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Corrosion in connector terminals
- Issues with wheel bearing assembly
