Lambda probe for Renault Duster
Content
Not all car owners thoroughly understand the principle of operation of the car, the functionality of individual mechanisms. Such unpopular elements include a lambda probe, or, as it is also called, an oxygen sensor. This device sends information about the ratio of air and gasoline in the combustion chambers to the system. Protection, a monitoring mechanism, and balancing of indicators that are optimal for work are triggered from data. Due to the correct performance of its tasks, the lambda probe prevents destabilization of the Renault Duster engine.
The oxygen sensor requires regular diagnostics of defects in order to prevent them or eliminate them in a timely manner. If these duties are neglected, their failure to comply can lead to the complete failure of the entire vehicle. Therefore, it is necessary to diagnose Renault Duster.
Why do I need a lambda on a Duster
The French auto industry, or rather its products, is liked by buyers. Many note the comfortable control and high-quality operation of the system. But often in a car, the failure of the exhaust system is due to the failure of the oxygen sensor, which is often associated with improper maintenance of the car.
The lambda probe is responsible for controlling the amount of air in the exhaust system. The necessity and importance of harmonizing substances is due to the danger of system failure due to overpressure inside. On Renault Duster models, for example, with an engine capacity of 1,6 and 2,0, there are usually two such devices, located before and after the catalyst. The quantity and position are determined by the need to control pressure before and after fuel injection into the system.

1 - control sensor in the exhaust manifold
Installed on the exhaust manifold. The task is to measure the amount of air in the exhaust gases, and then transfer the information received to the computer. Using the signals received from the device, the engine control unit changes the fuel injection system to stabilize the optimal mixture composition.
If the control sensor malfunctions, increased toxicity of vapors is observed.
2 - diagnostics on the exhaust pipe behind the converter
Sensor No. 2, which controls the air concentration, is installed after the catalytic converter. Its functions are identical to the first device, the second device signals the presence of oxygen in the exhaust gases after the converter. If the system is working, the readings of lambda probes 1 and 2 will differ significantly.
Provided for Renault Duster, including models with an engine capacity of 1,6 and 2,0.
How to change oxygen sensors (lambda)
In case of problems with operation, the only way out is to replace, since the part cannot be repaired. The mechanism is visually a metal screw, its replacement does not require special skills and a lot of time.
Before deactivating the device, electronic scanners alert the driver to the presence of malfunctions. Obvious signs of a malfunction include: extraneous sounds, a decrease in vehicle power, an increase in fuel consumption.
To replace the control oxygen sensor, you will need the following tools:
- keys (10, 12, 14);
- ring key (22);
- end head (13);
- screwdriver.
The replacement procedure includes several stages:
- Disconnecting the negative battery cable.
- Removing the air filter housing.
- Separation of the pad.
- Removing a device.
Installation of a new device is similar, in reverse order.
To replace the diagnostic oxygen sensor, you need a key (22), a winch.
The procedure includes:
- Disconnecting the negative cable.
- Separation of pads, detachment of supports, harness.
- Loosen the clamp and remove the sensor.
Installing a new device is done in the same way, but in reverse order.
How and why to seal the second lambda connector in Renault Duster
There are times when the device works with minor errors. This occurs in situations such as excessive pollution by combustion products. In this case, it is not necessary to replace the part, it is enough to clean and seal the connector of the second lambda.
After disassembling the Renault Duster, the protective cap is removed and treated with a special tool. After the end of the second lambda connector, it is sealed with a special tool. This will provide sufficient insulation against possible oxidation and recontamination. The whole procedure on Renault Duster can be done independently.
What is a snag lambda probe
There is a mechanism that stabilizes the operation of the electronics, correcting the incoming signal - the lack of an oxygen lambda probe. There are two types:
- mechanical type. It is available and involves semi-automatic intake of harmful substances, pressure reduction by oxygen level. The instrument panel shows the normal operation of the catalytic converter while maintaining a slight overpressure, if uncomfortable, it gives a signal that eliminates the problem of the exhaust system.
- Electronic type. This is a multifunctional processor capable of changing the settings of the car's electronic system, pretending that work continues as usual.
The service life depends on the quality of the fuel, the poor performance of which can significantly reduce the life of the devices.
The correct composition of the chemicals will keep the engine running smoothly, maintaining its longevity without loss of potential. Internal cleaning is best done every 40 km.
