Aslan Manifold Pressure Sensor Issue
Summary of the thread
A 2015 Hyundai Aslan is experiencing intermittent check engine light, reduced engine power, poor response, and increased fuel consumption, suspected to be due to a faulty manifold pressure sensor or a large vacuum leak. A similar issue was resolved by checking for cracks or loose connections around the intake manifold, particularly in vacuum hoses. A thorough inspection by a workshop is recommended to diagnose and repair the problem effectively.

Thanks. I did a visual inspection, but didn't find anything obvious. Where exactly should I be looking for these cracks or loose connections?

When mine went, it was almost impossible to see. It was a tiny split in one of the vacuum hoses near the manifold. Unless you have access to a smoke machine, it's probably best to get it checked by a workshop. Cost me 235€ to fix the sensor and the leakage.

Understood. I appreciate the insight. I'll take it to a trusted workshop for a proper diagnosis and repair, focusing on the manifold pressure sensor and potential vacuum leaks. Thanks again!

I had a similar problem with my Aslan! Same symptoms: check engine light, sluggish acceleration, and the fuel economy tanked. Have you checked for any obvious cracks or loose connections around the intake manifold? That's where I'd start.
