Failing Air Temp Sensor Cripples Chrysler 200 Performance

Had a similar issue with my Chrysler 300 (2014) when the car diagnostics showed an intake air temperature sensor problem. The symptoms matched exactly, rough running engine, significant power loss, and illuminated check engine light. The air temperature sensor had accumulated carbon deposits and was providing incorrect readings to the ECU. This caused the engine to run rich, leading to poor performance. A proper car sensor cleaning and calibration fixed the initial issues, but the sensor ultimately needed replacement as it was damaged beyond repair. This is a known weak point in these Chrysler models. The repair itself is straightforward and not particularly serious, but leaving it unfixed can lead to increased fuel consumption and potential engine damage over time. The air sensor is located in an accessible spot near the intake manifold, making it a relatively quick fix for a qualified mechanic. The diagnostic tool showed the sensor was reading temperatures incorrectly by about 20 degrees, which explained the engine management system confusion. After replacement, the engine performance returned to normal immediately. Worth noting that genuine parts are crucial for this repair, as aftermarket sensors often lead to recurring issues.

Thanks for sharing your experience. I had almost identical symptoms with my Chrysler 200 last winter. The temperature reading was way off, and the mechanic confirmed it was the intake air sensor failing. The engine would shake at idle and felt really sluggish. Curious what the repair ended up costing you? Mine was fixed about 6 months ago and I paid 280€ for parts and labor. Have you noticed any other issues pop up since getting it fixed? My car runs perfect now but I keep a close eye on the temperature readings just in case.

After the IAT sensor replacement on my Chrysler 300, the total came to 155€, which seems better than what you paid. The repair shop diagnosed the faulty intake air temperature sensor quickly and replaced it with an OEM part. Been running smoothly for over a year now with no engine issues or error codes. The diagnostic tool readings show consistent air temperature values now, and the engine response is perfect. No more rough running or power loss like before. Regular maintenance and keeping the intake air system clean helps prevent these problems from recurring. A working car sensor makes a huge difference, the engine computer gets accurate data and can adjust fuel mixture properly. Much cheaper to fix the IAT sensor early than risk engine damage from running with bad readings.

The shop visit turned out well after dealing with my rough-running Chrysler 200. The mechanic spotted the failing IAT sensor right away and confirmed my suspicions about the incorrect temperature readings. Total bill was 280€, probably a bit high, but the OEM part and labor were worth it for peace of mind. Six months later, the engine runs perfectly smooth with proper air temperature readings and no check engine lights. The power is completely back to normal. Regular checks of the intake system show everything working as it should. Much better experience than my previous shop visits. Good to hear others had similar fixes for less money, but at least the problem is solved. No more morning headaches with a shaking engine or struggling to merge onto highways. Will definitely keep monitoring the temperature readings through my scan tool just to catch any future issues early.
