What does Jaguar engine fault light P0420 mean?

Hello, the catalytic converter system performance is below the threshold (row 1. Have a great trip. If I can help you, please set it to, thank you!

The catalytic converter system performance is below the threshold (row 1).

You need to go to the store and use a special computer to read the fault code.

Hello, p0420 Chinese definition: catalytic converter system performance below the threshold (1st row.

Causes of failure include exhaust leakage near the exhaust pipe or exhaust manifold, catalytic tank failure, engine coolant temperature (ECT) sensor failure, engine fire or timing lag, dirty oil, faulty oxygen sensor, fuel system pressure too high, etc.

P0420 means exhaust pipe three-way catalytic converter failure.

There are 3 ways to quickly resolve the P0420 fault.

The first is: replace the original Jaguar three-way catalytic converter, remember not to change the auxiliary factory, the auxiliary factory will not be on for a long time.

The second is to install a part like this part of the TDTAS faulty lamp to repair the data to remove the P0420 faulty lamp.

The third way is: use the car computer to enter the engine ECU background and turn off this P0420 fault (some cars can, some cars can't).

Of course, there are many other ways to solve it, if you want to solve it quickly, I recommend these 3, I hope it can help you.

As follows:

1. Three-way catalytic conversion failure caused by overheating damage caused by lack of fire or over-dilute mixture.

2. Catalytic conversion failure due to excessive oil consumption and poisoning caused by fuel pollution.

Replace Jaguar. The original three-way catalytic converter of the vehicle.

That's it, remember not to change the auxiliary factory, the auxiliary factory will not be long before the lights will be turned on or install the TDTAS fault lamp to solve the dock, that is, the shielded joint, which is used to repair the P0420 fault lamp.

Introduce. Jaguar, a well-known British luxury car brand, was born in 1922 and was founded by Sir William Lyons; It is now part of the Tata Group of India.

Its. Entering China in 2004, Jaguar has three major products in the Chinese market: X series luxury sports sedan, Type series luxury sports car, and PACE series luxury coupe SUV.

In 2004, Jaguar officially entered the Chinese market. In 2015, Jaguar released its first SUV model, the XEL, a luxury sports sedan. In 2018, Jaguar's first luxury electric coupe, the Suvi-Pace, was launched at the Beijing Motor Show.

There are two ways to quickly resolve the P0420 fault.

The first is: replace the original three-way catalytic converter of Jaguar vehicles, remember not to change the auxiliary factory, the auxiliary factory will not take long to turn on the light or install the TDTAS fault lamp solution dock, that is, the shield joint, used to repair the P0420 fault lamp.

Hope it helps.

Summary. Hello, glad to answer for you! Fault Code:

P03433-00 refers to the high level circuit of camshaft position (CMP) sensor A, whether it is a first-row sensor or a single sensor. Camshafts are used to control the opening or closing of valves.

In the variable valve timing system, the electronic camshaft control valve or oil control valve adjusts the angle of the camshaft by changing the oil pressure of the camshaft adjuster according to the instructions of the engine control module, so as to ensure that the valve can be opened or closed in the best possible state. The causes of camshaft position sensor failure include camshaft position sensor line failure, electronic control module failure, etc. In this case, there will be a failure**.

Hello, glad to answer for you! Fault code: P03433-00 refers to:

Refers to the high-level circuit of the camshaft position (CMP) sensor A, whether it is the first row of sensors or the single sensor Yinkai. The camshaft is used to control the opening or closing of the valve. In the variable valve timing system, the electronic camshaft control valve or oil control valve adjusts the angle of the camshaft by changing the oil pressure of the camshaft adjuster according to the instructions of the engine control module, so as to ensure that the valve can be opened or closed in the best possible state.

The causes of camshaft position sensor failure include camshaft position sensor line failure, electronic control module failure, etc. In this case, there will be a malfunction.

Hello, glad to answer for you! In the event of a malfunction**, do not rush to replace the sensor. First of all, it is necessary to determine whether the timing system is installed correctly, observe whether the timing system has a tooth skipping phenomenon, whether the control part of the variable timing system is working normally, and whether the execution mechanism is stuck in the sedan chair.

Whether the timing belt gear is damaged or misaligned with the shaft, if all the above checks are in good condition, you need to consider replacing the sensor, and don't forget to troubleshoot the fault code after the replacement is completed.
