Product description

Capacitive intake manifold absolute pressure sensors are not yet widely used in automobiles, except in the D-injection engines of a few sedans such as Ford. When the capacitive intake pressure sensor or its connecting circuit fails, it can also detect the connection between the sensor and the power supply voltage, signal voltage and wiring harness. For details about the model, see their standard parameter values. At the same time, you can also use a multimeter to test the frequency of the intake pressure sensor. The test method is: turn on the ignition switch, but do not start the engine, the intake pressure sensor output signal frequency is about 160Hz; Deceleration frequency is about 80Hz; The idle frequency is about 105Hz. If the intake pressure output signal disappears or exceeds the specified standard value (frequency less than 80Hz or greater than 160Hz), the sensor is faulty and needs to be repaired or replaced. Specializing in the manufacture of intake manifold absolute pressure sensor, hydraulic pressure sensor, water pressure sensor, refrigerant pressure transmitter, air conditioning pressure transmitter, etc.
