Symptoms of an ageing oxygen sensor
Typical average lifetime of an upstream O2 sensor is 80,000-120,000 Km
This is an average, below symptoms can happen earlier:

Location of the O2 sensor on the Dacia Duster and preparatory works for accessing it
- The upstream lambda sensor on the Dacia (or Renault) Duster, here equipped with the K4M 1.6 16V engine, is located on the exhaust outlet, just after the exhaust manifold.
- Start by removing the air resonator upstream of the air filter (air box).
- Use a ratchet wrench with the lambda sensor-specific socket mounted on it.
- Extend your wrench using a ball joint and then two extensions, as shown in the photo on the right.
Dismounting and refitting the Oxygen sensor on Dacia or Renault Duster
Disconnect the sensor connector and push it out of the metal bracket to which it is attached.
Bend the sensor wire, insert the 22mm slotted socket, and apply sufficient force to unscrew the sensor.
Expect a significant amount of force, given the need to use a ball joint. Without a ball joint, the ratchet handle will touch the brake booster, making it impossible to loosen it.

Make sure you purchased the same probe, as they all screw in the same way. The connectors also differ.
Note how the threads on the new probe are greased (right) to make it easier to screw in.
Use only graphite or copper grease in case the sensor in your possession is not supplied with grease.

Tighten the new oxygen sensor to 5 mKg.
Remember to secure the connector, connect the other end, and refit the air box (resonator).
