Prius oil temperature sensor fault

Hey, I had something similar happen on my Prius (don't remember the year exactly). Was the error intermittent, or constant? Check the sensor connector itself for corrosion or loose pins. That's often the culprit.

Thanks for the tip! The error seems constant. Where exactly is the oil temperature sensor located? Any advice on how to properly inspect the connector?

Okay, constant error definitely points more towards the sensor or wiring. As for location, it's usually near the oil filter or the oil pump. Visual inspection is key – look for any green gunk or broken wires. Honestly, if you're not super comfortable with electrical stuff, might be worth getting a workshop to take a look.

Appreciate the help. Took it to the workshop – you were right, turned out to be a corroded connection. 95€ later, all sorted! Thanks again!
