Where is the fault manifold pressure sensor of Volkswagen Magotan p0 106?

P0 106: The performance of the circuit range of the absolute pressure and atmospheric pressure of the intake manifold is faulty. Check the power supply voltage. Unplug the wiring harness plug of the intake manifold pressure sensor, and measure the voltage between the power terminal and the ground terminal on the wiring harness plug with a voltmeter, which should be 4.0-6.0V Otherwise, it is necessary to further check whether the circuit between the intake manifold pressure sensor and the computer is conductive. If there is an open circuit, replace or repair its electric control circuit harness. Close to the intake pipe.

Factors affecting intake manifold pressure;

1. Throttle opening: The smaller the throttle opening, the greater the suction effect formed by the piston during intake, and the greater the vacuum suction of the intake manifold, that is, the lower the intake manifold force.

2. Engine speed: The higher the engine speed, the greater the suction force formed by the piston during air intake, and the greater the vacuum suction force of the intake manifold, that is, the lower the intake manifold force.

3. Sealing performance: including the sealing of intake manifold and cylinder. The better the sealing performance, the greater the suction force formed by the piston during intake, and the greater the vacuum suction force of the intake manifold, that is, the lower the intake manifold force.

Precautions for using intake pressure sensor:

1. Protect the transmitter from corrosive or overheated media.

2. Prevent dregs from depositing in the conduit.

3. When measuring the liquid pressure, the pressure tap should be opened at one side of the process pipeline to avoid the accumulation of sediment and slag.

4. When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so as to facilitate the injection of accumulated liquid into the process pipeline.

5, pressure catheter should be installed in the place where the temperature fluctuation is small.

6. When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer tube (coil) to prevent the working temperature of the transmitter from exceeding the limit.

7. When the intake pressure sensor fails, it may lead to abnormal idling of the engine, or backfire or smoke in the intake pipe of the engine. The owner should repair the intake pressure sensor in time to ensure its normal operation.
