How to repair Buick LaCrosse P0443 fault code

Fault code: P0443.

You can check the throttle opening, see if the gasoline is compliant, and if all of the above is okay, look for the idle sensor.

It is mainly the evaporative discharge system purge control valve circuit, and the causes of failure include: evaporative discharge system purge actuator circuit failure, purge control valve failure, electronic control module (PCM or ECM) failure, etc.

Hello your fault code P0443 means, Evaporative Emission System Purge Control Valve Circuit Evaporative Emission System directs gasoline vapor from the tank into a tank containing activated carbon that can absorb gasoline vapor. The engine then uses fresh air to blow these gasoline vapors into the engine's combustion chamber. This fault code appears if the ECU detects that the evaporative discharge system purge solenoid control circuit voltage is outside the normal calibration range.

The causes of the failure include the failure of the purge actuator circuit of the evaporative emission system, the failure of the purge control valve, and the failure of the electronic control module [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The implication is that the evaporative emission control system purge control valve circuit is faulty. It is recommended to replace the purge solenoid valve or test the wiring harness at both ends.

Hello! It is recommended that you go to the repair shop to clear it with a special computer, and I hope mine will help you [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The P0014 is an exhaust camshaft position actuator. Just swap it out. Just clear a fault code again.。。 Isn't it particularly easy to rush from P to D gear???

The P0014 is an exhaust bai camshaft position actuator. Just change it. Just clear a fault code again.

Actuators: Specialized in process control systems.

The actuator is composed of two parts: an actuator and a regulating mechanism. The regulating mechanism directly changes the parameters of the production process through the actuator, so that the production process meets the predetermined requirements. The actuator takes the control information from the controller and converts it into the output of the drive regulator (e.g., angular or linear output).

It also employs appropriate actuators, but the requirements are different from those of the regulating mechanism. The actuators are installed directly on the production site, sometimes under harsh working conditions. Whether it can maintain normal operation directly affects the safety and reliability of the automatic adjustment system.

New car claims, overinsured replacement camshaft actuators.

1. The sensor itself is damaged;

2. The line connection is unreliable;

3. The plug is soaked in water or other foreign objects;

4. The signal disk of the crankshaft position sensor is abnormally runout;

5. There are iron filings at the end of the sensor test.

The fault code needs to be connected to the 4S store to check the code to know the specific cause of the failure.

Hello, this is recommended to go to the store to check the code.

SAIC-GM Don't answer the P0342 fault code, the occurrence of such a situation indicates that SAIC-GM Buick Kaiyue combustion chamber carbon deposition is caused by excessive carbon deposits, SAIC-GM Buick Kaiyue combustion chamber carbon deposition needs to be cleaned, this problem can be eliminated, cleaning SAIC-GM Buick Kaiyue carbon insulation specific operation steps are as follows:

1. Run the SAIC-GM Buick Kaiyue engine to the normal working water temperature and turn off the engine.

2. Clean up the dust removal shed on the surface of the SAIC-GM Buick Kaiyue engine.

3. Remove the spark plugs of the four cylinders of SAIC-GM Buick Kaiyue.

4. Add cleaning agent to the cleaning machine.

5. Insert the cleaning head into the spark plug.

6. After soaking for 10 minutes, use a negative pressure tube to suck out the foam.

7. Install the four spark plugs of SAIC-GM Buick Kaiyue, and it is completed.
