Did the sensor have a connector on it or did you have to try and wire the connector into it?

wire

I made sure I wired it right and the conection was right and I double checked it as well
Infiniti Mechanic: Mike V., Infiniti Mechanic replied 1 year ago

Ok

I would say it's highly likely the sensor didn't get wired in right. These are a real pain to wire in and I usually avoid them. If you mix up the heater wire with the actual power wire or ground it can really cause a problem. I usually suggest aftermarket plug and play.

Before I condemn this though, what is the actual code you are getting?

Ok, give me a moment to pull this one up please.

Infiniti Mechanic: Mike V., Infiniti Mechanic replied 1 year ago

Ok, this is really a pretty basic wiring setup however if you have the orange/blue wire crossed with the solid white wire it's sending the wrong signal to the computer.

This is the issue I usually run into with the universal sensors, you can't generally tell what color wire on the actual sensor is for the signal VS the heater signal.

I think you may want to try one with the connector already installed to be honest.
