Extended Product Information

FAQs

Is this a universal oxygen sensor?

No, this is a vehicle-specific sensor designed for use in the post-catalytic converter position on compatible Honda models.

Can I use this sensor in the pre-catalytic position?

No, sensors calibrated for post-catalytic monitoring have different response characteristics than those used upstream of the converter.

Does this sensor come with a wiring harness?

Yes, this sensor features a 4-circuit configuration with the required connector for plug-and-play installation.

Do I need to calibrate the sensor after installation?

Most modern vehicle ECUs will automatically detect the new sensor, but it is recommended to clear existing codes and perform a drive cycle.

Why is the sensor heated?

The heater allows the sensor to reach its optimal operating temperature faster, reducing emissions during the initial warm-up period after a cold start.

Troubleshooting

Check Engine Light persists after installation

Clear the fault codes from the vehicle's ECU using an OBD-II scanner, as they do not always reset automatically.

Sensor is stuck in the exhaust pipe

Apply penetrating oil to the threads and allow it to soak for several minutes; use a specialized oxygen sensor wrench for better leverage.

Pros and Cons

Pros

  • Ensures factory-grade precision for engine management
  • Helps improve fuel economy by providing accurate air-fuel ratio data
  • Durable construction designed for high-heat exhaust environments
  • Standardized 4-circuit wiring simplifies installation

Cons

  • Specific to post-catalytic converter placement only
  • Requires precise OEM part number matching to avoid fitment issues
  • Installation requires specialized tools for oxygen sensor removal

Setup, Compatibility & Care

Before installation, use a diagnostic scan tool to confirm that the sensor is indeed the source of the fault. The sensor is designed for specific Honda models; always cross-reference your vehicle's VIN or the old sensor's part number against the references 36532RSJE01, 36532RSJE010M2, 36532RSPE01, or 36532RSPE010M2. To install, ensure the engine is completely cool to prevent burns. Use an oxygen sensor socket to remove the old unit, clean the threads of the exhaust bung, and apply a small amount of anti-seize compound to the new sensor's threads (if not pre-applied). Do not touch the sensing tip with bare hands, as oil and skin debris can damage the ceramic element.
