Frequently Asked Questions
Do these sensors plug directly into the factory wiring harness?
Yes. These mount at the factory sensor locations with OEM connectors — no adapters or wiring modifications needed.
Will my check engine light go away once I install these?
If your light was triggered by a faulty rear oxygen sensor, yes. If it's caused by a different fault code, get a diagnostic scan first to confirm the sensor is the issue.
Can I replace just one sensor, or do I need both?
You can replace one, but since they age at similar rates, replacing both at the same time prevents a second sensor failure shortly after. This pair covers both rear positions.
