Does barometric pressure affect cars?
Will a malfunctioning Barometric Pressure Sensor illuminate the check engine light or affect vehicle operation? Yes, a failing BARO sensor can illuminate the MIL, and may cause drivability problems such as stumbling, stalling and sluggish acceleration.
What should barometric pressure be in a car?
If the location shown in your profile is accurate, ambient pressure should be around 29.7 in Hg, so your neighbor’s car seems to reflect the correct altitude. As @barbecue mentions, Wolfram|Alpha shows that 29.2 in Hg reflects an altitude of 205 m (674 ft) above sea level.
How does a barometric pressure sensor work in a car?
Vehicle engines may also come equipped with a barometric pressure sensor. This sensor detects subtle changes in atmospheric air pressure. It then converts this signal to an electrical signal that is sent to the PCM for interpretation.
What are the signs of a bad barometric sensor?
Common signs include poor engine performance, like sluggish acceleration, lack of power, and misfires, as well as the Check Engine Light turning on. The barometric sensor, also commonly known as the barometric air pressure sensor (BAP), is a type of engine management sensor commonly found on many vehicles.
How to check for a barometric pressure problem?
A mechanic may begin diagnosing this trouble code by first locating the barometric pressure sensor, the mass airflow sensor, and the throttle position sensor. Once the sensors have been located, the mechanic would then check the wiring and connectors for any obvious damage.
What happens to the barometric pressure of the intake manifold?
As your car accelerates under load, the engine vacuum also drops. A drop in engine vacuum means that the absolute pressure in the intake manifold has increased. Vehicle engines may also come equipped with a barometric pressure sensor. This sensor detects subtle changes in atmospheric air pressure.

Where are the Baro and MAP sensors located?
In most cases, the MAP sensor and BARO sensor are contained within the same housing. The MAP sensor is connected to manifold vacuum, while the BARO sensor is vented to the atmosphere. However, there are some vehicles where the MAP sensor and BARO sensor are stand-alone components.
