Premium Heater‑Equipped O2 Sensor for Nissan Exhaust Control

Keep your engine clean and efficient with this OEM‑grade lambda probe. It streams oxygen data to the ECU so fuel trims stay on target, power feels strong, and emissions remain low. The integrated heater speeds warm‑up, delivering closed‑loop control within seconds—even on cold mornings. Ideal for restoring factory performance and reliability.

Why this part is needed

The ECU requires precise exhaust oxygen feedback to maintain the 14.7:1 air‑fuel ratio. Correct feedback means smooth idle, better mpg, crisp throttle, and a protected catalytic converter.

How it works

A zirconia sensing cell generates a small voltage that swings lean to rich (about 0.1–0.9 V). The built‑in heater keeps the tip hot, so the signal stays stable during idling, short trips, and cold starts. The ECU trims injector pulse width based on this signal for clean combustion.

What happens when it fails ⚠️

• Check Engine light, poor fuel economy, and sluggish response
• Rough idle, hesitation, and weak acceleration
• Strong exhaust smell, dark smoke, and catalyst damage risk
• Emissions test failure; possible heater circuit fault codes

Fitment and install tips

• Verify connector and location (upstream/downstream)
• Keep the sensing tip clean; avoid oil, coolant, and silicone
• Apply anti‑seize to threads, torque to spec, clear codes, road‑test
