307 - Catalytic Converter Fault Error

Hello everyone, good forums. About 1.5 months ago, I bought a 2003 model 307 xt, which was my first car. When I bought it, there was an antipollution fault error in the vehicle, but the master I showed doesn't cause any problem because it is LPG. I ignored this error and bought the vehicle. However, in the last days, while he was in gasoline, he started to stop even before he was switched to LPG. Today, the vehicle dropped from traction while he was traveling at LPG and he gave Catalytic Converter Fault Error. How can I deal with this problem in the cheapest way in Ankara? I am a student, so I do not want to postpone and enlarge the problem further. Thank you in advance for the answers

By the way, about 10 km before Catalytic Converter Fault error, I bought 25 liters of gas from the oil office.

Make a diagnosis first on both gasoline and LPG.

Do you have any guesses? I read something like catalyst can do in the forum and when I bought the car, he said something about the master oxygen values I showed, could it be something like this. He said the antipollution error could be caused by something like the oxygen sensor style.

catalitics in my mind as an error, I took care of the traction problem with the liqui catalytic system cleaner, it is not a hundred percent, but there is a nice difference but the fault code did not go out, you can easily apply it with a flat screwdriver.

where and which brand did you buy?

liqui catalytic stsytem cleaner has video on how to do it on their site

today they connected the vehicle to the computer and gave the errors shown in the picture. The master said, delete the errors and check again after a while, he cleared the error, but after a few km I started to get the errors again and said that the problem was fluctuating when the vehicle was idling, but it might be from the throat butterfly, but it was expensive and suggested to wait for a while, do you have any guesses? Thank you in advance, I wish good forums.

4. we looked at the cylinder, unplug the oxygen sensors and use it like that

So where is this plug exactly and if I run the car and make a certain km will it hurt? I'm sorry I really have no idea thank you very much for all your help

If the problem was not solved, I had the same problem. I have the problem, I don't know if it is just in other vehicles but I saw the same error about 7 8 months ago on the road computer and the vehicle completely dropped from the traction before a slope and then stopped. It then continued to stop approximately 30 to 40 seconds after each run. I hardly parked in front of the house. The person I bought was working in a private peugeot service, I called him, said the catalyst will be clogged or the material will be renewed. Then I called a different master. He said it could be from a crank speed sensor or a gas pump. He also said it might be related to the ignition system. The vehicle, which stopped 10 to 15 times on the road for 1 km at night, worked without any problems in the morning, there was no problem with its traction. I took it to the second master I was looking for, we connected it to the computer, and the ignition error just seemed. He said that the spark plugs have been peeled, we changed them before, if he gives the same error for 2 or 3 days, he said. 3 hours later, the car gave the same warning and stopped. When I called the ignition, he said, "Is there a sound coming from the bottom of the seat at the back?" He tried to hit the tank from the bottom 1 2 times. On the same day we dismantled the gas pump, we installed a new one and I did not experience the same problem for a long time. I went to the same master, it looked from the ignition system. We removed the coil and replaced it with a new one. If the problem continues in the same way, you can try them as a solution. :) uivgen2020-05-29 07:37:45
