What to check
- Scan for additional diagnostic trouble codes to identify potential underlying system issues.
- Inspect the sensor wiring and connectors for fraying, looseness, or corrosion while turning the wheel to check for wire stress.
- Measure the sensor resistance using a multimeter and compare the values against manufacturer specifications.
- Analyze the sensor signal data with a scan tool while spinning the wheel to detect signal inconsistencies.
- Examine the reluctor wheel or magnetic ring for missing teeth, rust, or debris that could affect signal generation.
- Perform a continuity and short-circuit test on the wiring harness between the sensor and the ABS module.
