Jeep Compass Hybrid IAT Sensor Failure Fix Guide

Had a similar issue with my 2019 Jeep Cherokee Hybrid last winter. The engine issues started with inconsistent temperature readings and reduced performance, especially during cold starts. The check engine light came on and diagnostics confirmed a faulty intake air temperature sensor. The air sensor replacement was straightforward, but the root cause was more complex. Discovered corrosion had damaged the wiring harness connecting to the temperature sensor, requiring additional repairs. The car sensor issue affected the engine control module readings, causing the system to run a richer fuel mixture than necessary. While the temperature sensor itself is not a major component, its malfunction can seriously impact engine performance and fuel efficiency. The repair involved replacing both the sensor and damaged wiring. After fixing it, the engine performance returned to normal and fuel economy improved significantly. For the Compass Hybrid, this is not a common failure point, but when it happens, best to address it quickly to prevent potential damage to other engine components. The repair took about 3 hours at the shop, including diagnostic time and testing to ensure proper function after installation.

I had the exact problem on my Jeep Compass. The engine issues started showing up together with a weird car sensor reading. The mechanic found that the air temperature sensor was failing, leading to incorrect readings and poor engine performance. The fix worked perfectly and the engine runs great now. No related problems have come up in the 6 months since the repair. Did you end up getting yours fixed? Curious about the repair cost in your case, mine was around 400 Euro including labor. Any other engine issues pop up afterwards?

Good to hear your Compass is running well now. Got my intake air temperature sensor fixed 3 months ago. The repair was successful and cost 155 Euro total, which seems reasonable compared to your repair cost. The engine performance improved immediately after the faulty air sensor was replaced. No additional engine issues since the fix. The temperature readings are now accurate and stable, which has helped maintain consistent engine performance. The mechanic confirmed the air sensor was the root cause of the problems, and replacing it resolved all the symptoms we discussed. The repair has proven to be a lasting solution, with the engine running smoothly and efficiently. Worth noting that regular checks of the air temperature sensor can help catch similar issues early before they affect engine performance more seriously.

Thanks for sharing your experience. After hearing about your sensor repair, I decided to take my Compass to a trusted mechanic last week. The car diagnostics confirmed our suspicion about the IAT sensor issue. The mechanic found that the intake air temperature sensor had completely failed, causing the erratic engine behavior. They also discovered some minor wiring issues that needed attention. Total repair cost came to 320 Euro, which included replacing the temperature sensor, fixing the wiring, and a full diagnostic check. The repair took about 2 hours, and the difference in performance is remarkable. The engine runs smooth now, no more rough idle or performance issues. The check engine light is off, and fuel economy has improved noticeably. It was definitely worth fixing properly rather than trying temporary solutions. Three days of driving since the repair and everything works perfectly. The mechanic suggested regular checks of the air sensor connections to prevent similar issues in the future.
