What is the reason why the P0322 fault code does not hit the car?

P0328 fault code, which means that the detonation sensor 1 circuit is high (row 1 or single sensor). Generally, when the voltage is higher than the maximum value of the calibration, this fault code will appear. Workaround:

It is possible to check if the knock sensor is loose, if the circuit board is faulty, and if the fuel oil number is correct. And eliminate the fault code after troubleshooting.

The knock sensor is installed in the middle of the engine block, and the four-cylinder engine is installed between the 2nd and 3rd cylinders, or one between the 1 and 2 cylinders, and one between the 3rd and 4th cylinders. It is used to measure the jitter degree of the engine carrying Sakuraga, and it is used to adjust the ignition advance angle when the engine detonation.

If the ignition is too early, the exhaust circulation is poor, and the engine knocking caused by low-grade fuel will cause damage to the engine. When vibration or cylinder knocking occurs, it produces a small voltage peak, the greater the cylinder knocking or vibration. The greater the peak of the knock sensor manufacturer.

A certain high frequency indicates knocking or knocking, and knock sensors are typically designed to measure frequencies in the range of 5 to 15 kHz. When these frequencies are received by the control unit, the computer recorrects the ignition timing to stop the detonation from continuing, and the detonation sensor is usually very durable. So the sensor will only be damaged by its own failure.

When the engine knocks, a pressure wave is generated, the frequency of which is 1-10kHzThe pressure wave is transmitted to the cylinder block to produce vibration acceleration at the metal particles, and the accelerometer knock sensor detects the strength of the detonation pressure by measuring the vibration acceleration on the surface of the cylinder. Premature ignition is a major cause of detonation.

Since the engine is required to be able to produce maximum power, in order not to lose engine power and not to produce detonation, a knock sensor is installed to make the electronic control device automatically adjust the ignition time.

Hello, the P0322 fault code means that there is no signal in the engine speed input circuit of the ignition distributor. Workaround:

Check whether the plug of the crankshaft position sensor is in good contact, and check whether the plug of the computer board is in good contact, check whether the crankshaft position sensor circuit is open and short-circuited, if not, please replace the crankshaft position sensor.

Hello, the P0322 fault code means that there is no signal in the engine speed input circuit of the ignition distributor. Solution: Check whether the plug of the crankshaft position sensor is in good contact, check whether the plug of the computer board is in good contact, check whether the crankshaft position sensor circuit is open and short-circuited, if not, please change the crankshaft position sensor.

Summary. Causes of failure include faulty engine speed sensor, faulty or mismatched sensor wheels, faulty electronic control module (PCM or ECM), etc.

Causes of failure include faulty engine speed sensor, faulty or mismatched sensor wheels, faulty electronic control module (PCM or ECM), etc.

1. Check whether the crankshaft position sensor plug is in good contact, and check whether the plug of the computer board is in good contact, and check whether the crankshaft position sensor circuit is broken and short-circuited. 2. The crankshaft speed sensor of the engine, fault phenomenon: most of the cars cannot start the car early, because the PCM does not receive the engine speed signal, and does not provide fuel injection and high-pressure fire.

Exclusion method: The use of an oscilloscope for waveform detection is the most direct and effective.

P0322 Fault ** Solution:

The P0322 fault code indicates that there is no signal in the engine speed input circuit of the ignition distributor.

There is no signal in the input circuit. Causes of failure include sensor failure, sensor wheel failure or mismatch, electronic control module failure, etc. The sensor is a detection device that can meet the requirements of information transmission, processing, storage, display, recording and control.

Characteristics of sensors: miniaturization, digitalization, intelligence, multi-function, systematization and networking.

A short circuit in the sensor or a loose G28 will cause the engine to fail to start normally, delay the start time or turn off the engine. As long as there is a fault code, it is necessary to find professionals to repair, and professional testing equipment is required to detect fault codes.

After troubleshooting, it is necessary to remove the old relatives in time**. If it is not cleared in time, it will affect the normal driving. When clearing **, it must be carried out in accordance with the method of clearing the fault ** specified in the specified vehicle model.

Do not disassemble the battery cable at will to troubleshoot the fault code. This method is very unreliable, and the fault code will appear again after a long time, and it is very troublesome to repair.
