Baleno Engine Rough & Sluggish Due to IAT Sensor

Had exactly these symptoms on my 2016 Suzuki Swift last month. The IAT sensor malfunction caused similar problems, rough cold starts and sluggish acceleration. The air temperature readings were way off, making the engine management system run a rich fuel mixture. The air sensor replacement was straightforward. A competent mechanic can diagnose and fix this in about an hour. The temperature sensor sits right on the intake manifold and is easily accessible. The symptoms match perfectly, when the intake air temperature sensor fails, it typically sends incorrect readings to the ECU, leading to poor performance exactly as described. This is not a major repair and wont cause engine damage if fixed promptly. Key indicators that confirmed the IAT sensor failure: Check engine light, Rough running when cold, Poor acceleration, Erratic temperature reading on diagnostic scan Worth noting that contamination or wiring issues can cause similar symptoms, but given the vehicle age and mileage, a faulty temperature sensor is most likely. Best to have a proper diagnostic scan done to confirm before parts replacement.

Thanks for sharing your experience. My Baleno had similar engine issues last summer. Really reassuring to hear the IAT sensor fix solved it for you. The temperature readings on my diagnostic tool were all over the place too. Did you remember roughly what the total repair cost was? Also curious if youve had any other temperature sensor problems since the replacement?

After replacing the faulty intake air temperature sensor last month, my Swift has been running perfectly. The car diagnostics confirmed it was definitely the IAT sensor causing those erratic temperature readings. Total cost came to 155€ for parts and labor, which seems fair considering how much better the engine runs now. No other air sensor issues since the fix. The engine starts smoothly in all temperatures and the acceleration is back to normal. A proper diagnosis from a skilled mechanic made all the difference, they spotted the failing IAT sensor right away and fixed it within the hour. The investment was worth it to resolve those engine issues. Regular maintenance helps prevent these problems, but sometimes sensors just fail with age and mileage. If your air temperature readings are inconsistent, getting the IAT sensor checked is definitely the right call.

I finally took my Baleno to a trusted mechanic based on your advice. You were spot on, it was indeed the IAT sensor causing all those problems. The diagnostic tool showed the exact same erratic temperature readings you mentioned. Total repair came to 180€ which included a thorough check of the intake system. The mechanic was really transparent, showed me the old air sensor and explained how the faulty temperature readings were affecting engine performance. The car runs like new now. Cold starts are smooth, and that sluggish feeling is completely gone. No check engine light since the fix, and the air temperature readings are stable. Really glad I got it sorted before it led to bigger issues. This experience was way better than my previous repair attempts. Having a clear idea about the IAT sensor symptoms helped me communicate better with the mechanic. Thanks for helping me avoid unnecessary repairs.
