Infiniti P0136 Error Code: How to Fix It

Q: Can I drive with Infiniti P0136 error code?

You can drive short distances with P0136, but prolonged driving may damage your catalytic converter and reduce fuel economy. The engine may run rich, causing increased emissions and potential long-term engine damage.

Q: How much does it cost to fix P0136 on an Infiniti?

DIY repair costs $50-150 for the oxygen sensor plus tools if needed. Professional repair typically costs $200-400 including parts and labor, depending on sensor accessibility and local labor rates.

Q: What causes P0136 error code in Infiniti vehicles?

Common causes include failed downstream oxygen sensor, damaged wiring or connectors, exhaust leaks near the sensor, or rarely, ECM issues. Age and heat exposure are the primary factors in O2 sensor failure.

Q: How long do Infiniti oxygen sensors last?

Infiniti oxygen sensors typically last 60,000-100,000 miles under normal driving conditions. Severe driving conditions, poor fuel quality, or engine problems can reduce sensor lifespan significantly.

Q: Will P0136 cause my Infiniti to fail emissions testing?

Yes, P0136 will likely cause your vehicle to fail emissions testing because it affects the engine's ability to properly monitor and control exhaust emissions. The error must be resolved before passing inspection.

Abstract

The Infiniti P0136 error code indicates a malfunction in the oxygen sensor circuit for Bank 1, Sensor 2, which is the downstream O2 sensor located after the catalytic converter. This sensor monitors exhaust gases to help your engine management system optimize fuel mixture and emissions control.
