Atos oil pressure warning lamp and sensor fault

Could be a few things, but a faulty oil level sensor or a wiring issue are the most common. Have you checked the sensor's connector and wiring for any obvious damage or corrosion? Also, what's the mileage on your Atos?

Thanks! The mileage is currently at 73491 km. I looked at the connector, and it seemed okay, but I'm not really sure what I'm looking for in terms of corrosion. Could it be something else entirely, or am I on the right track?

Given the symptoms and the error code, a defective cable or plug connection to the sensor is highly probable. While it could theoretically be something else, the oil level sensor circuit is the logical first place to investigate. I'd recommend having a workshop take a closer look, just to be safe.

Alright, I appreciate the advice! I took it to a local workshop, and you were spot on. It was a corroded connector to the oil level sensor, just like you suggested. They cleaned it up and replaced a small section of the wiring. The total repair cost was 95€. Thanks again for pointing me in the right direction!
