Once the engine oil turns black, becomes thin, or contains sand, it should be stopped immediately. Prolonged failure to change the oil or using deteriorated oil not only fails to lubricate but also damages the engine. Low-viscosity engine oil flows better and can effectively reduce engine wear. Before a cold start, it is essential to preheat the car. The main purpose is to reduce wear and allow the engine to reach normal clearance, maintaining optimal working conditions.

Last time I encountered the Peugeot P1338 trouble code, it was quite a headache. As someone who enjoys DIY car repairs, I first tried to fix it myself. P1338 usually indicates an issue with the camshaft position sensor—it might be aging or loose, causing poor contact and resulting in engine shaking or difficulty starting. My first step was to pop the hood and check if the sensor connection was loose or dusty; sometimes cleaning off the dust does the trick. If that didn’t work, I’d use an OBD scanner to read the specific data and confirm whether the sensor itself was faulty. Replacing the sensor isn’t too hard—I’d look up tutorials online, generally disconnect the negative battery terminal, unscrew the old sensor, and install the new one. But you have to be careful not to mess up the wiring, as incorrect connections might blow a fuse. I’ve also dealt with other sensor issues, like the throttle position sensor P0120, which I handled similarly. After the repair, I’d take the car for a few test drives to see if the check engine light went off. If you lack experience, don’t force it—you might make things worse.

From my experience, the P1338 trouble code indicates an issue with the camshaft position sensor circuit. I would first use a diagnostic tool to read the vehicle's data stream and check if the sensor signal fluctuates. If the signal is unstable, it might be caused by wiring wear or connector corrosion. A simple solution is to disconnect the power supply and clean the sensor connector to prevent rust from affecting current conduction. If the sensor itself is faulty, replace it with a new one—buying OEM parts online is more cost-effective. Throughout the process, don’t overlook other related components, such as the timing chain, which can also trigger P1338 if misaligned. After repairs, perform an ECU reset, clear the trouble code, and take a test drive. Remember, regular maintenance of the sensor can prevent such issues and avoid engine stalling, ensuring safe driving.

I found that the P1338 trouble code often causes Peugeot vehicles to have starting issues or weak acceleration. I would first check the sensor wiring for any damage—removing the protective cover to inspect if the harness is worn out, leading to a short circuit. If that doesn't work, I would measure whether the sensor's resistance value is normal. If I can't handle it myself, I would take it to a professional shop where technicians can quickly diagnose it with specialized equipment. During daily driving, pay attention to the dashboard warning lights.
