Ecosport Water Sensor Fault

I had a similar issue with my old Opel Corsa. Check engine light, error codes, and rough running point to a sensor problem. Mine was a corroded connector on the fuel composition sensor. Inspect the wiring and connectors to your water sensor for damage, corrosion, or loose connections. Use contact cleaner on the connector pins. Have you checked the sensor's voltage output with a multimeter?

Thanks for the quick reply! What voltage range should I look for when testing the water sensor with a multimeter? Also, where is the water sensor located?

I can't give you exact voltage numbers for your Ecosport's water sensor, you'll need the repair manual for that. You want a consistent signal within a specified range; erratic jumps or drops indicate a problem. It's usually in the fuel filter housing or along the fuel lines. To be safe, I would bring it to a workshop. They can properly diagnose it and probably fix it in an hour. I spent more time tinkering with my Corsa than it was worth.

Thanks for the guidance! I brought my Ecosport to a workshop for a check. It was a defective cable connection to the water sensor. Repair cost was 95€.
