Which number is the Passat fuel pump relay?
1 Answers
Passat's main fuel pump relay is No. 372. Working principle of fuel pump relay: The fuel pump relay is an automated electrical switch that operates through electromagnetic induction. When the required oil pressure is reached, the pressure relay contacts close, sending this signal as an oil pressure normal signal to CNC or PLC systems as a condition for allowing equipment startup. When the pressure falls below the required level, the pressure relay contacts open, cutting off the control circuit, triggering an alarm, and stopping the machinery to protect personnel and equipment safety. Location of fuel pump relay: The fuel pump relay is located under the car's hood, on the left side of the engine. To locate the fuel pump relay, first open the engine hood.
