Chrysler 200 Charge Sensor Issues Causing Power Loss

Having some experience with these issues, I faced a similar problem with my 2013 Chrysler 300 last summer. The automotive sensor symptoms were nearly identical, engine light, reduced power, and that characteristic whistling noise. The charge sensor system was indeed the culprit, but the root cause turned out to be simpler than expected. After inspection, the mechanic found a loose connection where the air temperature sensor cable met the plug. The wire harness had worked itself loose over time, causing erratic temperature gauge readings and triggering the check engine light. The total repair cost was 95€, which covered diagnosis and fixing the cable connection. The actual repair took about an hour. The temperature fluctuation issues disappeared immediately after the repair. To help diagnose your specific case more accurately, could you share: Have you noticed any specific patterns when the symptoms occur? (cold starts, highway driving, etc.), Are there any other warning lights besides the check engine light? Has the car experienced any recent repairs or maintenance? Does the whistling sound change with engine speed? These details would help determine if your issue matches what I experienced or might point to something different.

Last service was completed at 31523 KM and the engine sensor issue started shortly after. The whistling noise is most noticeable during highway speeds and the check engine light remains constant. The temperature gauge shows normal readings during idle but fluctuates when accelerating. No other warning lights are present and no recent repairs besides routine maintenance were done. Would a full sensor replacement be necessary or could cleaning and checking connections resolve the issue?

Based on those symptoms and when they started appearing after your service, this really sounds similar to what I experienced with my Chrysler 300. The airflow sensor behavior matches exactly, especially the temperature fluctuations during acceleration while staying normal at idle. In my case, a full air temperature sensor replacement wasnt necessary. The service technician first checked and cleaned all connections around the air intake system. They found that during the routine maintenance, the air sensor wiring had been disturbed, causing intermittent connection issues. The cleaning and reconnection fixed the problem completely, no more whistling noise, normal engine power restored, and the check engine light turned off. The temperature gauge readings stabilized as well. Since your symptoms started after service, I would recommend: 1. Having the air sensor connections inspected and cleaned first 2. Getting the wiring harness checked for proper seating 3. Testing the airflow sensor functionality after cleaning This approach could save you money compared to immediately replacing the entire sensor unit. My repair was 95€ for diagnosis and fixing the connections. A complete sensor replacement would have cost around 350€. If cleaning and checking connections doesnt resolve it, then considering a sensor replacement would be the next logical step.

I appreciate all this detailed feedback. The connection issue definitely sounds like it could be the culprit in my case too, especially since the symptoms started right after the routine service. Going to have my mechanic check the air intake connections and wiring harness first before considering a full charge sensor replacement. Makes sense to start with the simpler fix that worked in your case. The matching temperature fluctuation patterns during acceleration and the timing after maintenance really point to a similar issue. Would much rather pay 95€ for cleaning and reconnection than 350€ for a new sensor if not needed. Will schedule the inspection this week and update once I know more. Thanks for helping narrow down the likely cause and saving me from jumping straight to replacing parts unnecessarily.
