Citroen Sm loss of power: the most common reasons

Let's see what can be the causes of your problem and how to fix it.

Citroen Sm: a flowmeter problem.

Le lack of power of your Citroen Sm may be due to an air flow meter problem. The purpose of this part of the engine block is to calculate the volume of air inside the engine block, in order to increase the capacities of the engine block. When this probe presents a problem, the injectors will no longer give the right amount of fuel. The consequence: a fall in power.

Air compression malfunction

Whether it concerns a compressor or a turbo compressor, the problem will be relatively identical. the compressor is responsible for propelling the air inside the engine block of your Citroen Sm. If it is damaged, the air level will sometimes drop. Since an engine requires the right mixture of air and fuel to operate, its capacities will therefore be reduced. Dig a little to find out the problem, because replacing it is relatively expensive.

The signal sent to your on-board computer means that it can go into safety mode. This is to avoid engine breakage or excess pollution. To overcome this problem, check the probe connections. This kind of problem is usually accompanied by an indicator light on the dashboard. Otherwise, go to a garage, the diagnosis will be more convenient. Be vigilant and see you soon!
