91h20-06180 Oxygen Sensor — Cat

This is an oxygen sensor designed to measure the amount of oxygen in the exhaust gases, providing crucial data to the engine control unit (ECU) for optimizing fuel combustion. It is manufactured to precise specifications, ensuring accurate readings and reliable performance unlike a contaminated or degraded sensor. Operators may notice decreased fuel efficiency, rough idling, or increased exhaust emissions when this sensor is not functioning correctly.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing oxygen sensor is often a decrease in fuel economy or the illumination of the check engine light. If left unaddressed, the engine may run poorly, leading to rough idling and increased pollution. Continued operation with a faulty sensor can lead to catalytic converter damage due to improper fuel mixture.

Installation Tip

Always allow the exhaust system to cool completely before attempting to remove the old sensor. Use a dedicated oxygen sensor socket for removal and installation to avoid damaging the wiring.

Service Note

Inspect the exhaust system for leaks and check the catalytic converter for signs of damage or clogging.
