What is the fault of Changan Xingguang car fault code P0300 ? How to fix it

Is it an occasional or multiple cylinders that detect misfires. The solution is to use tech2 for maintenance programming.

Common faults in low-voltage circuits: insufficient battery storage, poor or malfunctioning of the wire, battery tie-up, damage to distributors or Hall sensors, damage to ignition switch or poor wiring, damage to transistor ignition control unit or poor wiring. Most of the diagnostic methods for low-voltage circuit faults use ammeter or voltmeter to check the fault line by line to eliminate the fault point.

P0300 is a fault for engine misfire, and the situation is more complicated. If it only occurs at low speed, there is no problem at high speed, and the fault light does not flash, give priority to checking the oil system, whether the gasoline filter is blocked, whether the nozzle needs to be cleaned, only about 10 kilometers a day, the car can not be completely heated every day, it is easy to cause carbon deposition in the engine valve.

P0300 – Misfire detected by sporadic or multiple cylinders.

The causes of failure include cylinder mechanical failure, ignition system failure, camshaft position sensor failure, oxygen sensor failure, three-way catalytic converter failure, EGR jamming, engine computer failure, poor gasoline quality, etc.

If there is no abnormality in the engine, delete the fault code first.

Hello, the car engine P0300 fault code refers to the engine detection multi-cylinder misfire fault.

The fault system that produces this phenomenon includes the fuel injection system and the ignition system, which are basically faults of the circuit and electronic control, and it is recommended to find professional maintenance personnel for electrical and electronic control for testing and maintenance.

Check the inlet pressure, as well as the inlet flow value. If there is a problem with the timing system, the inlet pressure will change.

What does it mean.

The abnormal voltage of the camshaft position sensor is too low or too high. Uh-huh.

Is it an occasional or multiple cylinders that detect misfires. The solution is to use tech2 for dimensional wide training programming.

Common faults in low-voltage circuits: insufficient battery storage, poor or malfunctioning of the wire, battery tie-up, damage to distributors or Hall sensors, damage to ignition switch or poor wiring, damage to transistor ignition control unit or poor wiring. Most of the diagnostic methods for low-voltage circuit faults use ammeter or voltmeter to check the fault line by line to eliminate the fault point.

P0300 is a fault for engine misfire, and the situation is more complicated. If the collision only occurs at low speed, there is no problem at high speed, and the fault light does not flash, give priority to checking the oil system, whether the gasoline filter is blocked, whether the nozzle needs to be cleaned, only about 10 kilometers a day, the car can not be completely heated every day, it is easy to cause carbon deposition in the engine valve.

The fault code of Chang'an out of the scattered P034300 is caused by the abnormal camshaft signal, when the engine computer detects that the signal of the camshaft is not accurate, or the output signal correspondence with the engine crankshaft sensor corresponds to the deviation, this fault code will appear, you can first check the output signal of the camshaft sensor, the vertical line between the sensor and the computer and the timing of the engine, there is no problem after inspection, considering the fault caused by electromagnetic interference and damage to the engine computer itself, Check whether there is interference with the ignition coil, spark plug and power generator, there is no problem in these places, repair or replace the engine computer, and repair the engine computer separately at 300 yuan If it is not repaired, it will not be charged, and the local master of the car electrical instrument can be repaired.

Changan CS35 engine fault light is on, indicating that the engine has failed. The fault light is just a reminder of the status of the car Li stop information, now the engine computer is more and more sensitive, which is a good thing, timely report to the owner of their own status, convenient for the owner to repair and maintain in time. Changan CS35 engine fault light on what does the engine indicator light use to show the working condition of the vehicle engine, when the key door is opened, when the vehicle self-test, the indicator light is automatically extinguished after lighting, such as always on, it means that the engine of the vehicle has a mechanical failure, needs to be repaired.

There are two kinds of fault codes for engines: one is a temporary fault code, and the other is a permanent fault code; For example, when you go to the fast repair shop to maintain the car, read the code in time and find that there is a fault code, but the fault light is not on, which is a temporary old-fashioned fault code; If the engine computer finds a function abnormal, it cannot be determined whether it is a fault state, so it will generate a temporary fault code first, wait for continued verification, and if the fault state continues to appear, it will light up the fault lamp and become a permanent fault code. If the fault status does not continue, the temporary fault code is automatically cleared.
