Seat Altea Oil Temperature Warning Light

My 2014 Seat Altea with a gasoline engine is throwing some codes. The oil temperature warning light popped up, and I've got an error stored. The oil pressure warning lamp lights up as well. I'm suspecting the engine sensor, specifically the oil temperature sensor. I'm thinking the likely culprit is a defective cable or plug connection. Anyone else run into this?

Sounds familiar. I had similar symptoms on my old Renault Megane – oil pressure light acting up, plus a warning on the dash. For me, it also turned out to be a faulty sensor. Did you check the resistance of the temp sensor?

I haven't checked the resistance yet, I'll add it to my to do list. Where was the sensor located on your Megane? I'm trying to locate it on my Altea to check the cable and plug connections.

Mine was a pain to get to, near the oil filter housing. Given the symptoms and your suspicion of wiring, it's probably best to get a proper car diagnostics run at a workshop. Could be more than just the sensor, playing it safe is key.

Took the Altea to the shop. Diagnostics confirmed it was the engine oil temperature sensor. They replaced the sensor and fixed the wiring. Cost me 95€. Thanks for the help!
