Where does the barometric pressure sensor go in a Mercedes?
The barometric pressure sensor is linked towards the air flow/position potentiometer. And I know that one pin of the sensor goes to the connector 11 of the ECU harness. While the other 2 goes to the air position potentiometer.
What does a barometric sensor do in a car?
It is responsible for measuring the atmospheric pressure of the environment that the vehicle is driving in. Different environments will have different atmospheric pressures, which will have an affect on how the vehicle runs.
What are the symptoms of a bad barometric pressure sensor?
Poor engine performance, sluggish acceleration, and lack of power. A symptom commonly associated with a problematic barometric pressure sensor is a poorly performing engine. If the BAP sensor malfunctions, it can send an incorrect signal to the computer which may have a negative effect on engine performance.
How does the absolute pressure sensor work on a 1997 Nissan Maxima?
The absolute pressure sensor detects ambient barometric pressure and intake manifold pressure and modifies the voltage signal received from the ECM. As the pressure increases, the voltage rises. This was performed on a 1997 Nissan Maxima. Please check with your vehicle’s repair manual for testing parameters.

How to diagnose a boost pressure sensor problem?
When the ECM is operating in this mode, a loss of power will be present, as if the turbocharger was not operating. The best method for diagnosing faults with the boost pressure sensor is with the DRB III scan tool. Refer to the Diesel Powertrain Diagnostic Manual for more information.
How is the pressure sensor on a diesel engine tested?
Explains how to test the diesel injection fuel pressure sensor. This is 3 wire sensor, with reference, signal and ground. Common rail Diesel fuel injection is now the state of the art in engine injection. The Bosch Piezoelectric (crystal) injector operates using a crystal stack, usually Quartz, that changes size when energized.
