Frequently Asked Questions
- How many miles do O2 sensors last?
- Typically 60,000-100,000 miles. After that, they become sluggish and trigger slow-response codes.
- Should I replace all O2 sensors at once?
- Only replace the one that failed. But if all are original and high-mileage, doing them all saves future hassle.
