Freestar Oil Pressure Warning Light

Help! My 2004 Ford Freestar with a gasoline engine is throwing me for a loop. The oil pressure warning lamp keeps lighting up, plus there's a warning light on the speedometer and an error stored in the memory. I'm guessing it's the engine oil temperature sensor, but I'm not sure where to start looking.

Summary of the thread

A 2004 Ford Freestar is experiencing an oil pressure warning light issue, with additional warning indicators and an error stored in memory. The initial suspicion is a problem with the engine oil temperature sensor. A suggestion is made to check the sensor's cable and plug connection, as a faulty connection could cause incorrect readings. Ultimately, the issue is resolved by addressing the cable connection to the oil temperature sensor at a workshop.

I had a similar problem with my Freestar. Is the warning light constant, or does it flicker? I would check the sensor's cable and plug connection first. A defective connection there can cause all sorts of weird readings. Is it possible that it is just a faulty sensor?

Thanks! The light is mostly constant, but sometimes flickers a bit. Where exactly is that sensor located? I'm okay with checking the connections, but I don't want to mess with the wrong thing.

On mine, the sensor was a pain to get to, tucked away near the oil filter. Honestly, given the symptoms and the potential location hassle, I'd suggest taking it to a workshop. They can diagnose it properly and replace the sensor if needed. Could save you a lot of time and frustration.

You were right! Took it to the shop, and it was indeed the cable connection to the oil temperature sensor. Cost me 95€ to get it sorted. Thanks for pointing me in the right direction!
