The engine fault light is on after replacing the exhaust valve of Porsche Cayenne

Sensor problem; the sensors mentioned here include water temperature, crankshaft position, air flow, inlet temperature Degree, oxygen sensors, etc. When these sensors are damaged, have poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the data of the engine, which will cause the engine fault light to turn on.

The fault point is determined, replace the new secondary air pump for test drive, and observe whether the engine light will still light up. If the fault light lights up again, it will report a similar secondary air fault. It is necessary to disassemble the engine, dredge the exhaust gas pipeline, and replace the exhaust gas EGR valve. Several problems were found in this inspection. The water pump leaked antifreeze, and the pump and antifreeze need to be replaced.

The failure of the oxygen sensor will cause the mixed gas to be too thin or too thick, thus turning on the engine fault light. Air flow sensor: How much air enters the engine depends on the air flow sensor to calculate and convert the electrical signal, and then the car computer receives the signal with the optimal air-fuel ratio to determine the amount of fuel.

Porsche Cayenne check engine fault light on

1. Porsche Cayenne engine light on yellow light indicates that the engine has failed. Generally speaking, the indicator light on the combination instrument indicates that there is an abnormality in the component.

2. If the engine fault light is on caused by the sensor, you only need to replace or adjust the corresponding sensor. Oxygen sensor: There is an oxygen sensor before and after the ternary catalyst, which plays different roles.The front oxygen is used to detect the air-fuel ratio of the engine in different working conditions. The car ECU adjusts the fuel injection amount and calculates the ignition time through the signal.

3. Determine the fault point, replace the new secondary air pump for test drive, and observe whether the engine light will still be on. If the fault light lights up again, it will report a similar secondary air fault. It is necessary to disassemble the engine, dredge the exhaust gas pipeline, and replace the exhaust gas EGR valve. Several problems were found in this inspection. The water pump leaked antifreeze, and the pump and antifreeze need to be replaced.

4. The reason why the engine fault light is on. The combustion state is not good. The engine combustion state is the main reason why the engine fault light is on.

Cayenne refueling shakes in 2006, the engine fault light is on

1. Exhaust problem: Exhaust failure will also cause the engine fault light to turn on.The failure of post-oxygen sensors, ternary catalysts, exhaust camshafts and shaft tiles are all causes of exhaust problems, among which ternary catalysts are the most common.

2. Fault phenomenon: If the engine speed is unstable, the power is obviously insufficient, and there is a tempering phenomenon, it can be considered that the engine has a fault of the mixed gas being too thin.

3. The failure of the oxygen sensor will cause the mixed gas to be too thin or too thick, thus turning on the engine fault light. Air flow sensor: How much air enters the engine depends on the air flow sensor to calculate and convert the electrical signal, and then the car computer receives the signal with the optimal air-fuel ratio to determine the amount of fuel.

4. Clean the engine: Once the engine failure light is on, the owner should clean the engine in time. You can go to the repair shop to clean the accumulated carbon with a special cleaning agent.Add higher-label gasoline.

5. If the Porsche Cayenne engine light is yellow, it means that the engine is faulty. Generally speaking, the indicator light on the combination instrument indicates that there is an abnormality in the component.

6. The most common fault of jitter during acceleration is damage to the spark plug. The wear of the spark plug pole gap leads to insufficient ignition of the spark plug. The mixed gas is not fully burned, resulting in the acceleration and jitter. In addition, there are cracks in the ceramic part of the spark plug, causing the spark plug not to ignite, and a cylinder does not work. It will also lead to accelerated shaking.

... The dashboard shows that the start-stop mode is prohibited and the engine fault light keeps on. What's wrong?..

1. Fault phenomenon: If the engine speed is unstable, the power is obviously insufficient, and there is a tempering phenomenon, it can be considered that the engine has a fault that the mixed gas is too thin.

2. Here are some possible reasons and solutions: Ignition system problems: The engine failure light may be due to the failure of the ignition system, such as the failure of the ignition coil, spark plug or ignition line. This may cause the engine to be unable to burn fuel normally, causing jitter and engine fault lights to light up.

3. The specific analysis is as follows; sensor problems; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data. At this time It will cause the engine fault light to light up.

4. The reason why the engine fault light is on is that the plug of the sensor is loose. When the engine fault light is on, we can restart the vehicle or lightly test the joints of each wiring harness to check whether the fault light will turn off. In some cases, the engine fault light is on because the plug of the wiring harness is loose.

5. It may be that the sensor cannot receive the data from the engine due to an abnormality, which will cause the engine fault light to light up. The car owner should pull over in time to check whether there is a problem with the sensor.

6. Maintain the vehicle regularly and maintain good driving habits. If the oxygen sensor fails, the engine fault light will turn on, and the owner needs to repair or replace it. If the water temperature sensor fails, the engine will not be well cooled, which will reduce the service life of the engine. The coolant should be replaced in time.

How to eliminate the Porsche Cayenne engine fault light

Cleaning the engine: Once the engine failure light is on, the owner should clean the engine in time, and you can go to the repair shop to clean the carbon with a special detergent. . Add higher-label gasoline.

Start and turn off the vehicle three times in a row. Turn off the ignition and pull out the negative pole of the engine battery, wait for 30 seconds to connect it, and then try to start. It can be eliminated after using the fault detector to troubleshoot at the 4S store.

Cleaning the engine Once the engine fault light is on, the owner should clean the engine in time. At present, there are two correct cleaning methods: (1), go to the repair shop to clean the accumulated carbon with a special cleaning agent.(2) Clean the entire fuel system by yourself with good fuel additives, including removing carbon in the cylinder.

What is the reason why the Porsche Cayenne engine turns on the yellow light?

The causes of Porsche engine failure light are: oxygen sensor failure, poor engine maintenance, use of inferior oil, poor combustion of mixed gas, unclean air filter, air flow sensor failure, spark plug carbon accumulation, water temperature sensor damage, engine cylinder shortage.

Do you want to ask the reason why the Cayenne engine fault light is on? Sensor: Due to damage or other problems, the sensor failed to obtain the correct data. Oxygen sensor: There is an oxygen sensor in front and behind the ternary catalyst, and they play different roles.

The reasons for the engine failure of the car are: poor combustion condition, the addition of advanced gasoline, the throttle valve is dirty or there is something wrong with itself. Poor combustion condition: Poor combustion condition of the engine is the main reason why the engine fault light is on, which may be caused by carbon accumulation, poor quality of fuel additives and other reasons.
