First of all, hello. My car is a 2008 Peugeot 207, model 1.4 8 v, with approximately 236,000 kilometers on it. While driving, I suddenly received the ENGINE SYSTEM Faulty error and my car stalled on its own. Then, I turned off the ignition and started it again and it ran without any problems. I continued on my way. Later, it did the same thing again, I turned it off and on again. The next day, I got in my car, started it, and as soon as I started it, it started running at 2,000 rpm and the fan turned on. The same error was appearing on the screen again. I removed the terminal and went to the repair shop. Since the car was having a throttle body problem, we replaced the throttle body. We adapted it and the car seemed to be fixed, but it did the same thing again. By the way, when the error is indicated on the screen, the car loses traction and doesn't get gas. It does this in the morning or when I first start it, nothing happens; it warms up and so on. When the car is connected to the engine, it gives the following errors: P0121 - Throttle Position Sensor. Inconsistency between 2 traces - Continuous P1161 - Throttle position - Continuous - Compatibility P1153 - Motorized throttle programming. Lower stoppers failed - Continuous P0135 - Inlet oxygen sensor heater - Continuous - Short to ground / positive or open circuit I know one of the oxygen sensors is faulty. It's been like this since I bought it. We've been messing with the car a lot for a day or two. But the car hasn't improved, sometimes it goes away on its own, sometimes it doesn't. Has anyone experienced this before? How can I fix this problem? It's really annoying, it keeps me from sleeping. It suddenly stops in the middle of the street. It's strange that the car runs at 2,000 rpm when you first start it and then the fan comes on. I think there's probably a problem with either the brain or the wiring.

First of all, hello... First, the engine control unit needs to be tested. The vehicle's engine wiring needs to be checked. Finally, the throttle body connector and wiring should be checked. It's very difficult to pinpoint these types of faults because they don't always work. Your first step should be to test the engine control unit.
