What is the reason for no signal from the Audi boost pressure sensor?

[DiLilliana]

Audi boost pressure sensor no signal solution is as follows: Connect the ammeter in series in the circuit: If there is a problem with the pressure sensor, you can connect the ammeter in series in the 24V power circuit to check whether the current is normal. If it is normal, it means the transmitter is normal, and then you should check whether other instruments in the circuit are normal. Check the meter head: If the pressure sensor has a meter head, you need to check whether the meter head is damaged (you can first short-circuit the two wires of the meter head. If it is normal after short-circuiting, it means the meter head is damaged). If the meter head is damaged, you need to replace it with a new one. Check the power supply: Check whether the power supply of the pressure sensor is reversed and whether the positive and negative poles of the power supply are correctly connected. Measure the power supply of the pressure sensor: Check whether there is 24V DC voltage; ensure that the power supply voltage of the pressure sensor is greater than or equal to 12V (i.e., the input voltage of the transmitter power supply is greater than or equal to 12V). If there is no power supply, check whether the circuit is broken or whether the detection instrument is selected incorrectly (the input impedance should be less than or equal to 250 Pa), etc.
