What does an ionization gauge pressure sensor measure?

An ionization gauge pressure sensor measures the pressure of a gas by determining the number of gas ions present in a vacuum chamber. As gas pressure increases, more gas ions are formed through ionization, which the sensor can detect and convert into a pressure reading.


What is the function of a vacuum gauge?

A vacuum gauge is used to measure the pressure in a vacuum. Application for car is at the MAP sensors. Most fuel injected cars uses MAP sensors to provide instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a mass airflow sensor (MAF sensor) to detect the intake airflow.


What are examples of a vacuum?

Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.


What is the maximum vacuum pressure that can be achieved in this vacuum chamber?

The maximum vacuum pressure that can be achieved in this vacuum chamber is 10-6 torr.


What would cause a engine to stumble during acceleration?

An engine may stumble during acceleration due to issues such as a clogged fuel filter, dirty fuel injectors, a vacuum leak, or a malfunctioning sensor (e.g., MAF sensor). These problems can disrupt the proper air-fuel ratio needed for smooth acceleration and performance.

What is the sensor in the gooseneck on 1986 Monte Carlo with a 305?

If it has vacuum lines attached to it, it is probably a thermoswitch that controls the vacuum to the egr valve. If it has an electrical connection it is probably a engine coolant temp sensor.

Remove the vacuum hose from the sensor. Remove the sensor retaining screws. The sensor will come off. Reverse the process to install the new sensor.


How do you fix a P0107 code on a 1998 Jeep Wrangler 4.0?

That is a MAP sensor code, check to see if the sensor is returning at least .5 volts, if not check for 5 volt reference voltage on the connector. If you have voltage going in, and none or less coming back out replace the sensor, if no reference voltage check the connectors, wiggle them and monitor the voltage. If the wiggle test checks out, draw a vacuum on the MAP sensor vacuum port. As you add vacuum the voltage should decrease. With no vacuum, the MAP sensor should read around 4.5 volts. If there is no change in MAP sensor reading on the scan tool, replace MAP sensor.
