What does a Lambda sensor do?

The Lambda sensor monitors oxygen levels in exhaust gases and sends signals to the engine control unit to optimize fuel injection timing and fuel-air ratio for efficient combustion and lower emissions.

How often should a Lambda sensor be replaced?

Typically every 80,000-100,000 km or when the check engine light indicates an oxygen sensor fault.

Is this a genuine Lambda part?

This is an aftermarket replacement sensor manufactured to OEM specifications and compatible with original Renault sensors.

Which Renault models does this fit?

This ES10992-12B1 sensor is compatible with Renault vehicles equipped with 1.2L gasoline engines, including Clio, Twingo, and Kangoo models.

Will a faulty Lambda sensor affect performance?

Yes. A faulty oxygen sensor can cause poor fuel economy, reduced power, rough idling, and increased emissions.

What is the warranty on this sensor?

Warranty terms vary by seller; typically 12-24 months from purchase on aftermarket sensors.

Is professional installation required?

Installation requires basic mechanical knowledge and tools. The sensor threads into the exhaust manifold; professional installation is recommended if unfamiliar.
