Frequently Asked Questions
Will these clear my check engine light?
If your codes point to rear O2 sensor circuit failure, these will resolve it once installed and the system relearns. Bring a code reader to confirm the fault is actually rear sensor-related before ordering.
Do I need special tools to remove the old sensors?
An oxygen sensor socket (typically 22mm) makes removal easier, but a standard wrench works if you have clearance. The rear sensors are tight — expect some heat-soak. Let the exhaust cool before touching them.
What happens if I only replace one sensor?
The DME expects matching inputs from both rear sensors. Replacing only one will keep you in limp mode or trigger new codes. Both sensors in this pair are matched — install them together.
