map sensor testing\nthe map sensor can become faulty.\nyou need a vacuum/pressure clamp to check the map sensor. with this clamp you can vary the pressure in a controlled way across the whole measuring range, while checking the signal voltage with a multimeter. this simulates the operation of the sensor itself.\nthen check the power supply and ground of the sensor. the supply voltage must be 5 volts.\nif the sensor uses a hose, always check this hose for leaks.\n\nbetween which connections do you need to connect the voltmeter if you want to check the supply voltage of the map sensor?\na and c.\nb and c.\na and b.

Answer

Explanation:

Step1: Recall voltage - measurement principle

To measure supply voltage, connect across power and ground.

Step2: Identify power and ground in sensor connections

Typically, one connection is power and another is ground for supply - voltage measurement. Without a diagram showing A, B, C as power or ground, we assume standard practice where power and ground are the two relevant points for supply - voltage check. Usually, we connect the voltmeter between the power - supply connection and the ground connection.

Answer:

There is not enough information in the provided text to determine which of A, B, or C is power and which is ground. So, we cannot answer from the given options.
