Xterra Overheating Speed Sensor

I'm having a weird issue with my 2005 Nissan Xterra, gasoline engine. The engine's been overheating lately, and the check engine light popped on. I've noticed the radiator fan isn't kicking on like it should. I checked the fan blade and it spins freely, so I'm suspecting maybe the fan motor or a sensor somewhere. Has anyone else run into this?

A 2005 Nissan Xterra was experiencing engine overheating and a check engine light, with the radiator fan not activating as expected. Initial suspicion was on the fan motor or a sensor issue. A suggestion was made to consider a defective speed sensor as a potential cause. After taking the vehicle to a shop, it was confirmed that the speed sensor was indeed defective, and the issue was resolved.

Whoa, overheating is never good! I had something similar happen with my Xterra. Is it possible that the speed sensor is defective? What mileage do you have?

Interesting, I hadn't considered the speed sensor. I'm sitting at around 197353 km. Was your Xterra showing the same symptoms – overheating and the check engine light?

Yep, exactly the same! The engine was getting way too hot, and that darn light was on. Honestly, I'd get it checked at a workshop to be sure. I would not recommend driving for too long like this.

Thanks a lot for the advice! Took it to the shop, and it turns out you were right – defective speed sensor! Cost me about 250€ to get it sorted. Really appreciate the help!
