The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.

The center of a hurricane is characterized by very low what?
The center of a hurricane is characterized by very low air pressure. This low pressure contributes to the strong winds and storm surge associated with hurricanes.
What causes increases in barometric pressures?
Increases in barometric pressure are usually caused by the sinking of air masses or high-pressure systems in the atmosphere. These high-pressure systems bring more air molecules closer to the Earth's surface, resulting in an increase in pressure. Additionally, changes in wind patterns and weather systems can also lead to temporary increases in barometric pressure.
What is the threshold for low barometric pressure?
The threshold for low barometric pressure is typically considered to be below 29.92 inches of mercury (inHg) or 1013.25 millibars (mb).
Are tornadoes formed by low pressure?
Not directly, but the systems that produce tornadoes do have low barometric pressure.
How does humidity impact barometric pressure?
Humidity can impact barometric pressure by affecting the density of the air. When humidity levels are high, the air becomes less dense, causing a decrease in barometric pressure. Conversely, low humidity levels can lead to denser air and an increase in barometric pressure.
Does barometric pressure go up or down in tornadoes?
Barometric pressure typically drops significantly in the vicinity of a tornado due to the strong updrafts and intense low-pressure system associated with the storm.
What does code P0107 mean in a 98 Oldsmobile intrigue?
Trouble code P0107 means: Manifold absolute pressure or barometric pressure circuit low input
How low is low?
In meteorology low is the cold air low pressure system that often brings more bad weather do to the lower barometric pressure.
What is considered low barometric pressure and how does it affect weather patterns?
Low barometric pressure is typically considered to be below 29.92 inches of mercury. Low pressure systems are associated with unsettled weather, such as rain, storms, and strong winds. This is because air rises in low pressure areas, leading to the formation of clouds and precipitation.
What is considered normal barometric pressure and how does it affect weather patterns?
Normal barometric pressure is around 1013.25 millibars. Barometric pressure affects weather patterns by indicating the movement of air masses. High pressure typically brings fair weather, while low pressure can bring stormy conditions. Changes in barometric pressure can also influence wind patterns and precipitation.
Does the barometric pressure seldom change?
Barometric pressure typically changes frequently due to weather patterns, such as high and low-pressure systems moving through an area. These fluctuations can impact the weather conditions experienced in a specific location.
What type of weather does low barometric pressure usually create?
Low barometric pressure typically creates stormy or unsettled weather conditions. This can include cloudy skies, precipitation such as rain or snow, and possibly strong winds.
