0261230099 Automotive parts intake manifold absolute sensor

Product description

The maintenance steps of the absolute pressure sensor in the intake manifold are as follows: 1. The electronically controlled gasoline injection system, which uses the intake branch pressure sensor to indirectly measure the amount of air inhaled by the engine, usually checks the power supply voltage and output voltage of the sensor during maintenance; 2. Check the power supply voltage. Remove the harness plug from the intake pressure sensor, turn on the ignition switch (do not start the engine), and use a voltmeter to measure the voltage between the power terminal and the ground terminal on the harness plug. Replace or repair electronic control wire harness; 3, the output voltage check to eliminate the sensor, intake branch pipe and vacuum hose, so the sensor is directly connected to the atmosphere, and then open the ignition switch (do not start the engine), and the electronic control unit of the voltmeter plug money plate under different vacuum degree of output voltage, voltage value should reduce the increase of vacuum density, its change should meet the regulations, otherwise, replace the sensor. The intake pressure sensor reports a fault and the computer displays a fault code. Specializing in the manufacture of intake manifold absolute pressure sensor, common rail pressure sensor, engineering hydraulic sensor, injection molding machine special pressure transmitter, urea pressure sensor, brake pressure transmitter, etc.
