Mechanics is a rather Cartesian field. However if there is indeed a phenomenon that is sometimes hard to understand, it is an unstable idle or acceleration holes. Whether for a Toyota Prius 2, or any other model of automobile. However, we can help you understand. Indeed, the reason can come from a large number of engine components, or even electronic. To find the origin of the breakdown of your Toyota Prius 2, you must follow a strict procedure. But first, let's see the symptoms of a slowed down idle.
Idling problem on a Toyota Prius 2: the symptoms
Un unstable idle close to stall . This is completely the most common slow motion concern. This feeling that the vehicle will stall while driving at normal speed, or that the Toyota Prius 2 grazes . It may even happen that stalling occurs. It is therefore really dangerous for the driver. If so, don't wait too long to take care of it. We suggest that you do a check via the paragraph below. We can also understand that the Toyota Prius 2 has a concern for acceleration . No link in this case with a concern for idling. Losses of power and acceleration holes may appear for multiple reasons. We must avoid confusing these two different concerns. We suggest you read our posts related to power losses.
Toyota Prius 2: develop a diagnosis to understand the origin of idling
We have to start by performing various extremely simple checks, before going into even more detail.
Idling of the Toyota Prius 2: exhaust fumes.
A black smoke comes out of the exhaust. This often means that the air and fuel mixture is bad. But also that the air filter is cluttered. In both cases, an idle problem may appear on the Toyota Prius 2. A White smoke comes out of the exhaust. This time too it can come from a disturbance. White smoke is often water vapor. It is thus likely that it is a concern of admission or of the head gasket.
Engine components check
As we said, a problem of idling on this Toyota Prius 2 can come from many points. You will therefore need to take the time to inspect the engine carefully. However, it is recommended to be very careful and not to tamper with the components of the engine, as this could amplify the breakdown or divert the nature of the problem. We recommend of course going to a garage for a more detailed check. Here are the elements to check point by point.
- The first thing to do is check all of the hoses . The latter can be perforated or even detached.
- We will also have to examine the sensors and sensors of your engine. It is nevertheless difficult to control their proper functioning. Tutorials are easily found on youtube, and this usually requires electronic devices.
- Perform a control of pressures hydraulic. Again, pressure testing requires suitable equipment.
Idle malfunctions are common but are complex to diagnose. A visual check on the Toyota Prius 2 will allow you to have a clearer vision, but it is wiser not to tackle amateur DIY.
