Purpose and function in a diesel engine

The presented item belongs to the Air and fuel intake sensors category and is designed for diesel engines used in Peugeot 208 and 308 models with the 1.6 HDI engine. Integrating the air temperature sensor with the breather valve allows for:

• monitoring of intake air temperature by the engine control unit,
• controlled discharge of vapors from the crankcase system,
• maintenance of stable combustion parameters under various load conditions.

As a result, the intake system operates predictably, and the control unit has access to reliable data, which promotes smooth engine performance and reduces unwanted idle fluctuations.

Benefits of using the air temperature sensor with a breather valve

Using this type of solution in a 1.6 HDI engine provides a number of practical operational benefits. The most important include:

• Better control of the combustion process – accurate air temperature readings enable the control unit to precisely dose fuel.
• Reduction of contaminants in the intake system – the breather valve helps direct vapors in a controlled manner, which promotes the cleanliness of intake ducts.
• More stable engine operation across a wide range of ambient temperatures.
• Cohesive design of a single module instead of several scattered components.

For the user, this means more predictable vehicle behavior, especially in city traffic and during frequent cold starts, which are typical for diesel engines.

Product characteristics and fitment

The offered air temperature sensor with a breather valve is a component dedicated to Peugeot vehicles, which translates into a proper fit for the factory intake system. The product comes from the used parts segment, making it a reasonable compromise between cost and functionality, while maintaining a design consistent with the vehicle manufacturer's requirements.

Due to its use in a Diesel fuel type engine, the component is adapted to the specific operating conditions of diesel units – higher boost pressures, the presence of soot, and variable temperatures within the intake system. This is particularly important during mixed-cycle operation, where the engine often works in various load ranges.

Why choose used electronics and sensors?

In the case of components such as air temperature sensors or breather valves, choosing a verified used part can be a technically sound alternative to new replacements. However, it is crucial to ensure proper fitment based on OEM numbers and verify compatibility with the specific engine control unit version. A detailed discussion on the selection and installation of such components can be found in the guide Used automotive electronics – ECU modules and second-hand sensors, which explains, among other things, the principles of selection by part numbers, hardware and software compatibility issues, and the most frequently asked user questions.
