Estima oil temp warning light

My 2009 Toyota Estima with a gasoline engine is acting up. It has 182512 km. The oil temp warning light is on, and there's an error code. The oil pressure lamp sometimes comes on too! I suspect the oil temp sensor – maybe a bad cable or plug? Has anyone seen this before?

A 2009 Toyota Estima owner experienced issues with the oil temperature warning light and intermittent oil pressure light, suspecting a faulty oil temperature sensor or related wiring. Another Estima owner suggested checking the wiring connections before replacing parts. Upon inspection at a workshop, a corroded plug was identified and cleaned, resolving the issue without needing a new sensor.

Did this summary help you solve your problem?

Sounds familiar. I've got an Estima, and I had similar issues a while back. Was the sensor itself throwing the code, or were just the readings off?

I'm not sure about the exact error code. I only had the generic error readout and didn't check the code. Is there any easy way to find out?

Could be the sensor itself. But, given the intermittent oil pressure light, a bad connection sounds more likely. I'd get it to a workshop to check the wiring before swapping parts. It saved me money last time.

You nailed it. The shop found the plug corroded. They cleaned it up, and it's good as new. It cost 95€, but that's better than a new sensor.
